Triggering builds of dependent projects in Travis CI

Question

We have our single page javascript app in one repository and our backend server in another. Is there any way for a passing build on the backend server to trigger a build of the single page app?

We don't want to combine them into a single repository, but we do want to make sure that changes to one don't break the other.

Answer 1

Yes, it is possible to trigger another Travis job after a first one succeeds. You can use the trigger-travis.sh script.

The script's documentation tells how to use it -- set an environment variable and add a few lines to your .travis.yml file.
