Allocating available random Ports in a Maven Build

Wed, 07 May 2014 00:00:00 +0200

Recently in a project I encountered the following problem: The development team used Git with a branch-per-feature-like workflow and the integration server, Bamboo in this case, was configured not only to run the integration-tests for the master-branch but also for every change in a feature branch.

As the team developed a Java EE web application ports like 8080 occasionally were already bound and builds failed.

I knew a plug-in for Jenkins CI I to search for available ports and assign them to a build variable but I wanted to control such information directly within the Maven build life-cycle so I searched and finally found Sonatype’s Port Allocator Plug-in for Maven.
