nickwallen opened a new pull request #1522: METRON-2271 Reorganize Travis Builds URL: https://github.com/apache/metron/pull/1522 We are increasingly hitting the 50 minute time limit on our integration test job in Travis. This causes the entire Travis build to fail. My goal here is to make minor modifications to avoid these failures until we can come back for a more comprehensive review of our integration tests to address the issue of total run time. ### Background The way in which we organize the Travis build currently causes each job to build *all* of Metron, *every* time. Although we attempt to cache the local Maven repository to avoid repetitively building Metron, in practice all of the jobs in a build start roughly in parallel and so this cache is never used. The result is that every job builds all of Metron. As evidence review how long it takes for the license verification job to complete. While this should take a few seconds/minutes, this always takes 15+ minutes because the job does a full build of Metron. It is never able to re-use what was built and cached by any other job. ### Solution By reorganizing the build, so that each job only builds the modules that it needs (and avoid a one-size-fits-all "install" step) we save enough time to avoid breaching the 50 minute time limit on any individual job. In addition, I added names to each job to improve clarity in the Travis UI and split out the the UI tests so that the Alerts and Management tests run separately. These are the advantages that I see with this change. 1. This will prevent us from unnecessarily breaching the 50 minute time limit for the integration test job with minimal effort or risk as compared to re-architecting the integration tests. 1. We get more immediate feedback. If you messed up the licenses, you're going to know in a minute, rather than after 20 minutes. 1. We have a much more accurate picture of how long each step is taking. Previously the site-book appeared to take 16-18 minutes, but it is now very clear that it takes 1-2 minutes. 1. The total aggregate run time was previously 2.25-2.5 hours, but is now about 1.5 hours. This is less load on Travis and we like Travis, so let's help him out. See https://travis-ci.org/nickwallen/metron/builds/592235729 to see how this looks in Travis. ## Pull Request Checklist Thank you for submitting a contribution to Apache Metron.
