[Hawkular-dev] Maven, Continuous and Reproducible

Hi *, I think I found a way how to make our process more continuous, while staying with stock Maven and Components in separate git repositories. The core of the idea is that we actually do not need to release the components because they are not our deliverables (yes, except for Metrics). If we were able to declare the dependencies using git revisions and build them on the fly, we could get rid of both SNAPSHOTS and releases. I have written srcdeps-maven-plugin [1] today that does exactly that: * It collects dependencies with versions matching {whatever}-SRC-{git-commit-hash} * It checks out {git-commit-hash} of their sources to ~/.m2/dependency-sources * It changes the version in the sources to {whatever}-SRC-{git-commit-hash} * Builds the artifacts and installs them to the local repository * All the above happens before the dependency resolution starts so it is fully transparent for the rest of Maven. * The -SRC- dependencies are build only if they are not found in local repository - so they prolong the build only when upgrading. How to try it out: #Make sure that you have maven 3.2.5 or newer: mvn -version # build the plugin cd ~/git git checkout https://github.com/ppalaga/srcdeps-maven-plugin.git cd srcdeps-maven-plugin mvn clean install # build hawkular with the plugin cd ../hawkular git remote add ppalaga https://github.com/ppalaga/hawkular.git git fetch ppalaga git checkout -b 150819-srcdeps mvn clean install ...
