The .github repo proposed in post 2 now exists: GitHub - xwiki/.github: GitHub configuration shared by the XWiki repositories: default community health files, reusable workflows and the Renovate preset · GitHub
I’ve written up what’s in it and what changes for everyone in a separate thread, to keep this one about the checks themselves: New .github repo in the XWiki GH organization for shared GitHub configuration
Short version: quality-pr.yml and backport.yml are now single reusable workflows called by a small stub in each repo, the PR template / SECURITY.md / FUNDING.yml are served org-wide, and there’s a shared Renovate preset. Two things to be aware of here: the PR check is now named Quality / Analyze instead of Analyze, and the workflow is edited in xwiki/.github from now on, not in the three repos.
@tmortagne, you were right about java-version — there’s no such input, it’s read from the pom as you expected.
