Is there a way to workaround the issue locally?
Yes. Replace the Jenkins Maven job that is currently being used with a Jenkins Pipeline or a Jenkins Freestyle project that performs the same operations.
Seems like nobody feels responsible.
Tobias as stated by Marc Rohlfs in an earlier comment, this plugin is up for adoption. When a plugin is up for adoption, that means the current maintainer is not maintaining it and others have not yet started maintaining it. I think that makes your observation correct that nobody feels responsible for this plugin at this time.
As an open source project, Jenkins relies on the work of volunteers who are intentionally allowed to choose how much or how little they contribute. The current maintainer, Marc Rohlfs, is not able to commit time to maintain the plugin and has noted that the plugin is up for adoption. If others who need this plugin are willing to spend some of their time to maintain it, they can refer to the "Contributing to Open Source" document and the tutorial videos for suggestions to prepare to adopt the plugin. Fixing this issue would be a good contribution for a new maintainer. They would benefit from the fix and others would also benefit.
Would you like to adopt the plugin?
