OK, I tried something new. *Goal*: all the plugins in one Git repo (less CI jobs to set up - just one recursive multi-module maven build). *Constraint*: Plugins must be independently releasable.
*Test:* Take two modules from the Svn repo and check them in to master (the rest were deleted - test needs two and a parent pom in master). *Repository*: https://github.com/paul-hammant/ph_testplugins Of the two modules checked in, maven-changes-plugin is the one I attempted to release to my com/paulhammant/ group on 'Central. The workflow for the release of that single module is here https://github.com/paul-hammant/ph_testplugins/blob/master/CHANGES_PLUGIN_RELEASE_WORKFLOW.md *Result of Test:* failed, but in a surprising way and at a very late stage During the release:perform stage the maven tried to push to https://oss.sonatype.org/content/repositories/snapshots /com/paulhammant/testplugins-ph-chgs-pi/3.0.0-SNAPSHOT/testplugins-ph-chgs-pi-3.0.0-20170627.234743-1.jar which is nuts because I'm not trying to push to a SNAPSHOT, I'm trying to do a proper release of 3.0.0 (of my renamed to an obscure name plugin). The documentation for the <scm> part of the pom says that it honors the name of the local branch for the sequence of commits that the release plugin does. Which is exactly what you'd want. I've already tested it a dozen times and it does the right thing by way of tags too. It's only that SNAPSHOT weirdness during the upload that ends the experiment, and that's a fairly late stage piece. My plan was to go onto oss.sonatype.org and delete it from staging so it would ultimately go nowhere. Barring that bug, this would work for all of the Maven plugins in a single repo, meaning a lot less permutations for CI, albeit with a longer build per commit. I don't think that last is a big issue for this proposed repository. Any of you could clone the repo I have made, and do the same steps as CHANGES_PLUGIN_RELEASE_WORKFLOW.md document to get to the same place I got to (a 401 error from Sonatype's DAV infra). And one of you could tell me what I did wrong with the setup to encounter that snapshot issue :) - Paul
