Failed to build using gradle 7.0

[michaelhkay]

Attempting to build this with gradle 7.0 on Mac (I'm a gradle novice, so I seem to be in the target population for this sample...) I got the failure:

>XX javaparser-gradle-sample % gradle --warning-mode all shadowJar

> Configure project :
The testCompile configuration has been deprecated for dependency declaration. This will fail with an error in Gradle 7.0. Please use the testImplementation configuration instead.

> Task :compileJava FAILED

FAILURE: Build failed with an exception.

I got rid of the first error by changing testCompile to testImplementation, but I didn't understand the second error.

I got rid of the second error by change the line (near the end of build.gradle)

'Implementation-Version': version,

to

'Implementation-Version': archiveVersion,

I'm now getting another error

* What went wrong:
Execution failed for task ':compileJava'.
> Could not find tools.jar. Please check that /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home contains a valid JDK installation.

(It doesn't. That's not where Java gets installed these days...)
