Based on some feed-back from ApacheCon I just created a new job on Jenkins which will do a simple compilation (i.e. 'mvn compile') for pull requests sent to the ActiveMQ project (i.e. https://github.com/apache/activemq). Ideally the job would run a small subset of tests to provide high-level assurance that the PR won't break anything significant, but at this point I don't know what those tests would be so this is a simple first step. If anyone would like to contribute something (e.g. a Maven profile) that Jenkins could invoke to perform this general testing for PRs feel free. I can change the job to execute any Maven target.
The job is at https://builds.apache.org/job/ActiveMQ-PR-Build/. Justin
