15 days ago, Travis improved their cache system.
See here : travis-ci/travis-ci#4393
Official doc: https://docs.travis-ci.com/user/caching/
It fits perfectly what we need here, because every build is too different. And these new caches will be available to all PR.
What have been done here:
We won't see any improvment until this PR is merged, and after the merge, the 1st full build will cache everything, so benefits will be seen for the next builds.
@jdubois :
At the moment, let keep the 2 repo jhipster-travis-build or jhipster-travis-cache
I will tell you when you can delete them, maybe in 3 weeks~ to be sure this system works
@jhipster/developers :
You can manage cache here https://travis-ci.org/jhipster/generator-jhipster/caches
So when needed, we can delete them to let Travis rebuild correctly the cache
