The Bazel team is happy to announce a new version of Bazel, Bazel 0.19.

This document lists the major changes since Bazel 0.18.

General changes

• The --incompatible_expand_directories flag automatically expands directories in command lines. See the design document.

• The --loading_phase_threads flag now defaults to auto instead of 200, which at the moment corresponds to the number of CPUs. This is appropriate for most users. However, if your sources reside on a network file system, increasing this value may yield better analysis-time performance when disk caches are cold.

Android

• Fixed missing debug symbols when building native code with --compilation_mode=dbg that target Android ARM architectures by adding the -g flag.

C++

• Added --incompatible_disable_legacy_flags_cc_toolchain_api to deprecate legacy cc_toolchain Starlark API for legacy CROSSTOOL fields. Tracking issue is #6434. See the instructions for migration.

• Runfiles in cc_test: the C++ runfiles library (@bazel_tools//tools/cpp/runfiles) can now create Runfiles objects for tests. See //tools/cpp/runfiles/runfiles_src.h in the Bazel source tree for documentation.

• :cc_binary link action no longer hardcodes -static-libgcc for toolchains that support embedded runtimes (guarded by --experimental_dont_emit_static_libgcc temporarily).

• The flag --experimental_enable_cc_configuration_make_variables is removed, use --incompatible_disable_cc_configuration_make_variables instead.

Java

• Bazel now requires a JDK to be installed as it no longer falls back to the internal JDK if the --javabase flag is not set. Instead, Bazel now searches for a JDK within the JAVA_HOME and PATH environment variables. If Bazel cannot find a JDK, it will not be able to run Java builds.

Code Coverage

• LcovMerger was renamed to CoverageOutputGenerator. Please use

--coverage_report_generator=@bazel_tools//tools/test/CoverageOutputGenerator/java/com/google/devtools/coverageoutputgenerator:Main

instead of the previous

--coverage_report_generator=@bazel_tools//tools/test/LcovMerger/java/com/google/devtools/lcovmerger:Main

• You can now enable a new coverage method for C++ rules that use gcc with the --experimental_cc_coverage flag. The flag will use gcov instead of lcov to collect coverage information. This new implementation fixes
  some of the C++ coverage correctness issues ( respecting --instrumentation_filter and --instrument_test_targets flags ).
  There have been observed faster clean and incremental times when invoking bazel coverage ( small overhead compared to test runtimes instead of 2x test runtime ), but more measurements need to be done.

Other Changes

• Add --apple_compiler and --apple_grte_top options. These provide the equivalent of --compiler / --grte_top for the toolchain configured in --apple_crosstool_top.

• There is now a same_pkg_direct_rdeps query function. See the query documentation for more details.

• Propagating remote errors to the user even if --verbose_failures=false is set.

• Add number of configured targets to analysis phase status output.

• Bazel will now check stderr instead of stdout to decide if it is outputting to a terminal. --isatty is deprecated, use --is_stderr_atty instead.

Future Changes

We will do incompatible changes in Bazel 0.20. We encourage you to migrate in advance (or report any migration difficulty) with the following flags:

• --incompatible_disable_late_bound_option_defaults
• --incompatible_disable_depset_in_cc_user_flags
• --incompatible_disable_cc_toolchain_label_from_crosstool_proto
• --incompatible_disable_cc_configuration_make_variables
• --incompatible_disable_legacy_cpp_toolchain_skylark_api
• incompatible_disable_legacy_flags_cc_toolchain_api
• --incompatible_remove_native_git_repository
• --incompatible_remove_native_http_archive
• --incompatible_disallow_conflicting_providers
• --incompatible_range_type

Cherry picks:

• 2834613:
  Include also ext jars in the bootclasspath jar.
• 2579b79:
  Fix toolchain_java9 on --host_javabase= after
  7eb9ea1

General changes

• New bazelrc file list.
  If you need to keep both the old and new lists of .rc files active
  concurrently to support multiple versions of Bazel, you can import the old
  file location into the new list using try-import. This imports a file if it
  exists and silently exits if it does not. You can use this method to account
  for a user file that may or may not exist

• .bazelignore
  is now fully functional.

• The startup flag --host_javabase has been renamed to
  --server_javabase to avoid confusion with the build flag
  --host_javabase.

Android

• The Android resource processing pipeline now supports persistence
  via worker processes. Enable it with
  --persistent_android_resource_processor. We have observed a 50% increase
  in build speed for clean local builds and up to 150% increase in build
  speed for incremental local builds.

C++

• In-memory package //tools/defaults has been removed (controlled by
  --incompatible_disable_tools_defaults_package flag). Please see
  migration instructions
  and migrate soon, the flag will be flipped in Bazel 0.19, and the legacy
  behavior will be removed in Bazel 0.20.

• Late bound option defaults (typical example was the --compiler flag, when
  it was not specified, it’s value was computed using the CROSSTOOL) are removed
  (controlled by --incompatible_disable_late_bound_option_defaults flag).
  Please see migration instructions
  and migrate soon, the flag will be flipped in Bazel 0.19, and the legacy
  behavior will be removed in Bazel 0.20.

• Depsets are no longer accepted in user_compile_flags and user_link_flags
  in the C++ toolchain API (controlled by
  --incompatible_disable_depset_in_cc_user_flags flag) affects C++ users.
  Please see migration instructions
  and migrate soon, the flag will be flipped in Bazel 0.19, and the legacy
  behavior will be removed in Bazel 0.20.

• CROSSTOOL is no longer consulted when selecting C++ toolchain (controlled by
  --incompatible_disable_cc_toolchain_label_from_crosstool_proto flag).
  Please see migration instructions
  and migrate soon, the flag will be flipped in Bazel 0.19, and the legacy behavior will be removed in Bazel 0.20.

• You can now use toolchain_identifier attribute
  on cc_toolchain to pair it with CROSSTOOL toolchain.

• C++ specific Make variables
  are no longer passed from the CppConfiguration, but from the C++ toolchain
  (controlled by --incompatible_disable_cc_configuration_make_variables flag).
  Please see migration instructions
  and migrate soon, the flag will be flipped
  in Bazel 0.19, and the legacy behavior will be removed in Bazel 0.20.

• Skylark api accessing C++
  toolchain in ctx.fragments.cpp is removed (controlled by
  --incompatible_disable_legacy_cpp_toolchain_skylark_api flag).
  Please migrate soon, the flag will be flipped
  in Bazel 0.19, and the legacy behavior will be removed in Bazel 0.20.

• cc_binary link action no longer hardcodes
  -static-libgcc for toolchains that support embedded runtimes
  (guarded by --experimental_dont_emit_static_libgcc
  temporarily). Proper deprecation using --incompatible flags will follow.

Java

• Future versions of Bazel will require a locally installed JDK
  for Java development. Previously Bazel would fall back to using
  the embedded --server_javabase if no JDK as available. Pass
  --incompatible_never_use_embedded_jdk_for_javabase to disable the
  legacy behaviour.

• --javacopt= no longer affects compilations of tools that are
  executed during the build; use --host_javacopt= to change javac
  flags in the host configuration.

Objective C

• objc_library now supports the module_name attribute.

Skylark

• Adds --incompatible_expand_directories to automatically expand
  directories in skylark command lines. Design doc:
  https://docs.google.com/document/d/11agWFiOUiz2htBLj6swPTob5z78TrCxm8DQE4uJLOwM

• Support fileset expansion in ctx.actions.args(). Controlled by
  --incompatible_expand_directories.

Windows

• --windows_exe_launcher is deprecated, this flag will be removed
  soon. Please make sure you are not using it.

• Bazel now supports the symlink runfiles tree on Windows with
  --experimental_enable_runfiles flag. For more details, see
  this doc.

Other Changes

• A new experimental option --experimental_ui_deduplicate has been added. It
  causes the UI to attempt to deduplicate messages from actions to keep the
  console output cleaner.

• Add --modify_execution_info, a flag to customize action execution
  info.

• Add ExecutionInfo to aquery output for ExecutionInfoSpecifier
  actions.

• When computing --instrumentation_filter, end filter patterns with
  "[/:]" to match non-top-level packages exactly and treat
  top-level targets consistently.

• Added the bazel info server_log command, which obtains the main Bazel
  server log file path. This can help debug Bazel issues.

• aapt shrink resources now properly respect filter configurations.

Important changes:

• In the future, Bazel will expand tree artifacts in runfiles, too,
  which causes the sandbox to link each file individually into the
  sandbox directory, instead of symlinking the entire directory. In
  this release, the behavior is not enabled by default yet. Please
  try it out via
  --incompatible_symlinked_sandbox_expands_tree_artifacts_in_runfile
  s_tree and let us know if it causes issues. If everything looks
  good, this behavior will become the default in a following
  release.

Notice: Bazel installers contain binaries licensed under the GPLv2 with
Classpath exception. Those installers should always be redistributed along with

Incompatible changes:

• Loading @bazel_tools//tools/build_defs/repo:git_repositories.bzl
  no longer works. Load @bazel_tools//tools/build_defs/repo:git.bzl
  instead.
• If the same artifact is generated by two distinct but identical
  actions, and a downstream action has both those actions' outputs
  in its inputs, the artifact will now appear twice in the
  downstream action's inputs. If this causes problems in Skylark
  actions, you can use the uniquify=True argument in Args.add_args.
• If the same artifact is generated by two distinct but identical
  actions, and a downstream action has both those actions' outputs
  in its inputs, the artifact will now appear twice in the
  downstream action's inputs. If this causes problems in Skylark
  actions, you can use the uniquify=True argument in Args.add_args.
• Labels in C++ rules' linkopts attribute are not expanded anymore
  unless they are wrapped, e.g: $(location //foo:bar)
• If the same artifact is generated by two distinct but identical
  actions, and a downstream action has both those actions' outputs
  in its inputs, the artifact will now appear twice in the
  downstream action's inputs. If this causes problems in Skylark
  actions, you can use the uniquify=True argument in Args.add_args.
• New bazelrc file list.
• Windows: when BAZEL_SH envvar is not defined and Bazel searches
  for a suitable bash.exe, Bazel will no longer look for Git Bash
  and no longer recommend installing it as a Bash implementation.
  See issue #5751.
• New bazelrc file list.

New features:

• The aquery command now supports --output=text.
• Java, runfiles: the Java runfiles library is now in
  @bazel_tools//tools/java/runfiles. The old target
  (@bazel_tools//tools/runfiles:java-runfiles) is deprecated and
  will be removed in Bazel 0.18.0.
• Java, runfiles: the Java runfiles library is now in
  @bazel_tools//tools/java/runfiles. The old target
  (@bazel_tools//tools/runfiles:java-runfiles) is deprecated and
  will be removed in Bazel 0.19.0 (not 0.18.0, as stated earlier).

Important changes:

• Allow @ in package names.
• Remove support for java_runtime_suite; use alias() together with
  select() instead.
• Python wrapper scripts for MSVC are removed.
• [JavaInfo] Outputs are merged in java_common.merge().
• Faster analysis by improved parallelization.
• --experimental_shortened_obj_file_path is removed.
• Introduce the --remote_cache_proxy flag,
  which allows for remote http caching to connect
  via a unix domain socket.
• No longer define G3_VERSION_INFO for c++ linkstamp compiles, as
  it was a duplicate of G3_TARGET_NAME.
• Added support for Android NDK r17. The default STL is now
  libc++, and support for targeting mips, mips64 and ARMv5
  (armeabi) has been removed.
• Add aquery command to get analysis time information about the
  action graph.
• Fixed compatibility with aar_import when using aapt2. AAPT2 is
  now supported for Android app builds without resource shrinking.
  To use it, pass the --android_aapt=aapt2 flag or define
  android_binary.aapt_version=aapt2.
• Code coverage is collected for Java binaries invoked from sh_test.
• java_common.compile creates the native headers jar accesible via
  JavaInfo.outputs.native_headers.
• Deleting deprecated no-op flag --show_package_location
• The JDK shipped with Bazel was updated to JDK10.
• Rename the startup flag --host_javabase to --server_javabase to
  avoid confusion with the build flag --host_javabase
• newly added options --experimental_repository_hash_file and
  --experimental_verify_repository_rules allow to verify for
  repositories
  the directory generated against pre-recorded hashes. See
  documentation
  for those options.
• Removed the gen_jars output group
• --subcommands can now take a "pretty_print" value
  ("--subcommands=pretty_print") to print the
  arguments of subcommands as a list for easier reading.
• follow-up to
  1ac359743176e659e9c7472
  645e3142f3c44b9e8
• A rule error is now thrown if a Skylark rule implementation
  function returns multiple providers of the same type.
• When using Bazel's remote execution feature and Bazel has to
  fallback to local execution for an action, Bazel used
  non-sandboxed
  local execution until now. From this release on, you can use the
  new
  flag --remote_local_fallback_strategy= to tell Bazel
  which
  strategy to use in that case.
• Execution Log Parser can now, when printing it out, filter the
  log by runner type
• A rule error is now thrown if a Skylark rule implementation
  function returns multiple providers of the same type.
• Removed the gen_jars output group
• Removed the gen_jars output group
• Set --defer_param_files to default to true.
• Sort attribute lists in proto-form query output to fix
  non-deterministic genquery output.
• Replace 0/1 with False/True for testonly attribute
• bazel now supports a .bazelignore file specifying
  directories to be ignored; however, these directories still
  have to be well founded and, in particular, may not contain
  symlink cycles.
• Add more detailed reporting of the differences between startup
  options.
• update data binding to 3.2.0
• For Android incremental dexing actions, Bazel now persists its
  DexBuilder process across individual actions. From our
  benchmarks, this results in a 1.2x speedup for clean local builds.
• The standard xcode_VERSION feature now always uses exactly two
  components in the version, even if you specify --xcode_version
  with
  more or fewer than two.
• A rule error will be thrown if a Skylark rule implementation
  function returns multiple providers of the same type. Try the
  --incompatible_disallow_conflicting_providers flag to ensure
  your code is forward-compatible.
• Removed notion of FULLY_STATIC linking mode from C++ rules.
• In documentation, we've renamed Skylark into Starlark.
• Execution Log Parser can now, when printing it out, reorder the
  actions for easier text diffs
• Linkstamps are no longer recompiled after server restart.
• Use VanillaJavaBuilder and disable header compilation in
  toolchain_hostjdk8. The default toolchain will soon drop
  compatibility with JDK 8. Using a JDK 8 host_javabase
  will only be supported when using 'VanillaJavaBuilder' (which
  does not support Error Prone,
  Strict Java Deps, or reduced classpaths) and with header
  compilation disabled.
• In the future, Bazel will expand tree artifacts in runfiles, too,
  which causes the sandbox to link each file individually into the
  sandbox directory, instead of symlinking the entire directory. In
  this release, the behavior is not enabled by default yet. Please
  try it out via
  --incompatible_symlinked_sandbox_expands_tree_artifacts_in_runfile
  s_tree and let us know if it causes issues. If everything looks
  good, this behavior will become the default in a following
  release.

• Bazel crashes with a StackOverflowError on Windows (See #5730)
• Bazel requires a locally installed JDK and does not fall back
  to the embedded JDK (See #5744)
• Bazel fails to build for Homebrew on macOS El Capitan (See #5777)
• A regression in apple_static_library (See #5683)

  openjdk: update macOS openjdk image. Fixes #5532
• f45c224:
  Set the start time of binary and JSON profiles to zero correctly.
• bca1912:
  remote: fix race on download error. Fixes #5047
• 3842bd3:
  jdk: use parallel old gc and disable compact strings

Incompatible changes:

• The $(ANDROID_CPU) Make variable is not available anymore. Use
  $(TARGET_CPU) after an Android configuration transition instead.
• The $(JAVA_TRANSLATIONS) Make variable is not supported anymore.
• Skylark structs (using struct()) may no longer have to_json and
  to_proto overridden.
• The mobile-install --skylark_incremental_res flag is no longer
  available, use the --skylark flag instead.

New features:

• android_local_test now takes advantage of Robolectric's binary
  resource processing which allows for faster tests.
• Allow @ in package names.

Important changes:

• Option --glibc is removed, toolchain selection relies solely on
  --cpu and --compiler options.
• Build support for enabling cross binary FDO optimization.
• The --distdir option is no longer experimental. This
  option allows to specify additional directories to look for
  files before trying to fetch them from the network. Files from
  any of the distdirs are only used if a checksum for the file
  is specified and both, the filename and the checksum, match.
• Java coverage works now with multiple jobs.
• Flip default value of --experimental_shortened_obj_file_path to
  true, Bazel now generates short object file path by default.
• New rules for importing Android dependencies:
  aar_import_external and aar_maven_import_external.
  aar_import_external enables specifying external AAR
  dependencies using a list of HTTP URLs for the artifact.
  aar_maven_import_external enables specifying external AAR
  dependencies using the artifact coordinate and a list of server
  URLs.
• The BAZEL_JAVAC_OPTS environment variable allows arguments, e.g.,
  "-J-Xmx2g", may be passed to the javac compiler during bootstrap
  build. This is helpful if your system chooses too small of a max
  heap size for the Java compiler during the bootstrap build.
• --noexpand_configs_in_place is deprecated.
• A tool to parse the Bazel execution log.
• Support for LIPO has been fully removed.
• Remove support for --discard_actions_after_execution.
• Add --materialize_param_files flag to write parameter files even
  when actions are executed remotely.
• Windows default system bazelrc is read from the user's
  ProgramData if present.
• --[no]allow_undefined_configs no longer exists, passing undefined
  configs is an error.
• In remote caching we limit the number of open
  TCP connections to 100 by default. The number can be adjusted
  by specifying the --remote_max_connections flag.

0.15.0

Release 0.15.0 (2018-06-26)

Baseline: b93ae42

Cherry picks:

• 4b80f24:
  Add option to enable Docker sandboxing.
• 6b16352:
  Allow disabling the simple blob caches via CLI flag overrides.
• 4ec0a75:
  Use BUILD.bazel instead of BUILD for external projects

Incompatible changes:

• Bazel now always runs binaries in with "bazel run" in
  interactive mode. The "--nodirect_run" command line option is now
  a no-op.
• "bazel run --noas_test" is not supported anymore.
• Indentation on the first line of a file was previously ignored.
  This is now fixed.

New features:

• C++,runfiles: to access data-dependencies (runfiles) in C++
  programs, use the runfiles library built into Bazel. For usage
  info, see
  https://github.com/bazelbuild/bazel/blob/master/tools/cpp/runfiles
  /runfiles.h

Important changes:

• Bazel now allows almost all 7-bit ASCII characters in labels.
• Remove vestigial java_plugin.data attribute
• Bazel supports including select Java 8 APIs into Android apps
  targeting pre-Nougat Android devices with
  --experimental_desugar_java8_libs
• Flag --incompatible_disable_glob_tracking is removed.
• SkyQuery's rbuildfiles now returns targets corresponding to
  broken packages.
• Introduce build support for providing cache prefetch hints.
• Update the skylark DefaultInfo documentation to spell out
  runfiles, data_runfiles and default_runfiles
• An internal action for symlinking runfiles will use Command
  instead of a Spawns. This should have no functional chages; the
  only user visible consequence should be that the internal action
  is no longer be included in statistics when calculating processes
  count.
• --batch is deprecated
• execution strategies line no longer handles differently the case
  where all processes have the same strategy.
• The --experimental_remote_spawn_cache flag is now enabled by
  default, and remote caching no longer needs --*_strategy=remote
  flags (it will fail if they are specified).
• android_binary.aapt_version='aapt2' now supports en_XA and ar_XB
• Added --apple_enable_auto_dsym_dbg flag.
• non_propagated_deps has been removed from objc_library and
  apple_binary.
• For Android projects, Bazel now supports building fonts as
  resources. See
  https://developer.android.com/guide/topics/ui/look-and-feel/fonts-in-xml
  for more information on the feature.
• With --incompatible_no_support_tools_in_action_inputs enabled, Skylark
  action inputs are no longer scanned for tools. Move any such
  inputs to the newly introduced 'tools' attribute.
