Branching and merging with git in PMD

Sunday, March 13, 2016 • PMD git

This post is about, how your git history might look like, if you consequently fix bugs on branches and merge this bugfix-branches into the release branches. In this case, I used the method described earlier in “Roadmap and source code branches” in New PMD Release 5.4.0: Always create a new branch, that can be merged in the release branches, determined by git merge-base. Then, after the bugfix, merge this branch into the release branches, avoiding a fast-forward merge by using git merge --no-ff.

This post is about how to fix a bug in PMD - the project mess detector. PMD is a source code analyzer tool for Java and many other languages. It checks your source for common programming mistakes so you don’t repeat them. However, as with all software, it is not perfect. PMD itself has bugs which lead to either false positives, e.g. when PMD reports a mistake which is not really a problem. Or to false negatives, which means, that PMD doesn’t detect the potential bug.
