I have a Grails 2.5.6 project that runs tests on Travis CI, and a couple of days ago I started to get errors related to unresolved dependencies.
On my side the app didn't changed any dependencies, it seems something wrong is on the maven repo.
This is the log I'm getting:

| Run 'grails dependency-report' for further information.
I don't have any clues on what is going on or how to fix it. Any pointers are welcome.
This seems to be a recurring issue with Travis accessing Maven Central. See https://github.com/travis-ci/travis-ci/issues/6593 and https://github.com/travis-ci/travis-ci/issues/10055
The suggested workaround is to use sudo: true in your .travis.yml.
