If your tests are passing locally, and you've not made any configuration
changes to robolectric, then it will probably be ok. We typically run the
tests locally before merging a request.
I assume you're referring to a failed Travis build that is was kicked off
as part of submitting your pull request. Travis is mainly used as a canary,
and for feedback to developers submitting pull requests. Unfortunately, the
Travis build system does not get the attention it deserves. The jenkins
build system running on http://ci.robolectric.org is the real 'ci of
record'. It has credentials and configurations that push passing snapshot
builds to maven central. The ability to push snapshots from Travis was not
possible (the last time I investigated), because of the need for private
keys and credentials.
