Maarten and I took a look at the failing projects today and have restored
the matrix of JDKs and Maven versions in the Jenkins pipelines. Windows
hosts apparently do not have JDK 16 installed. I've added a comment in
"maven-wagon" was failing because of recent changes to the Jenkins pipeline
and after fixing that they are green again .
"maven-common-artifact-filters" started working again after a re-run . I
hope it's not flaky, but rather hope that the recent Jenkinsfile changes
have fixed the issue.
"maven-source-plugin" is indeed waiting on a new release of plexus-archiver.
