Unable to clone into TaxonomyTree to build

[najouamghazli]

Hello,

I am trying to install RDPTools for like one week now, and I have a problem when clonning into TaxonomyTree.

After running

git submodule update

I get

...
Cloning into 'SequenceMatch'...
remote: Enumerating objects: 133, done.
remote: Total 133 (delta 0), reused 0 (delta 0), pack-reused 133
Receiving objects: 100% (133/133), 108.01 KiB | 0 bytes/s, done.

Submodule path 'SequenceMatch': checked out 'd9e902f7a38b2889d9c295b1c6d32af890b0f6e6'
Cloning into 'TaxonomyTree'...
fatal: unable to connect to github.com:
github.com[0: 140.82.118.3]: errno=Connection timed out
fatal: clone of 'git://github.com/rdpstaff/TaxonomyTree' into submodule path 'TaxonomyTree' failed

I am using ant 1.9.6 and java 8 jdk, I can't install java 7 jdk because I'am using Ubuntu 18.04 and java 7 is no longer available for Ubuntu 16.04 and higher.

Any ideas on how to solve this problem are much appreciated.

Thank you
