Anything else?

Bisecting identifies jenkinsci/jenkins#6432 as the culprit → https://github.com/jenkinsci/pom/releases/tag/jenkins-1.73 → #322 / #327

I recently asked the security team to fix a regression that was introduced in the same time period (approximately a year ago), and I received a response that the security team does not and has never committed to fixing regressions regardless of when the issue is raised, and when I asked about the relevance of when the issue was raised I received no response.

🤷‍♂️

Interestingly, the issue is no longer reproducible as described since jenkinsci/jenkins#8204. Looking at the diff, this would indicate #506 no longer finds the directory.

Confirmed by adding debug output, which results in the following paths for the file TestRuntimeMojo#getManifestEntry operates on:

• Old: $HOME/…/war/target/classes
• New: $HOME/.m2/repository/org/jenkins-ci/main/jenkins-war/2.413-SNAPSHOT/jenkins-war-2.413-SNAPSHOT.war
