Somehow pulled in an incompatible version of `guava`. Jenkins bundles 11.x, and without a lot of advanced acrobatics¹ you cannot override this. If your plugin bundles some third-party libraries, they may be depending on a newer version of Guava and Maven picks that version for tests, breaking everything. Check mvn dependency:tree and use an `<exclusion>` as necessary. Unless the third-party library actually _requires_ newer Guava features, in which case you have problems. Also, did your tests stop working with no code changes? If `master` was blue/green until now, check whether your `Jenkinsfile` is using, say, buildPlugin(configurations: recommendedConfigurations()) which is nondeterministic. If tests broke inside a PR (I would recommend a PR for all nontrivial changes, even if you are a sole maintainer, just for trackability and CI), link to that from any post to the mailing list. ¹Read: https://www.jenkins.io/doc/developer/plugin-development/dependencies-and-class-loading/#pluginfirstclassloader-and-its-discontents -- You received this message because you are subscribed to the Google Groups "Jenkins Developers" group.
