Kalle Niemitalo added a comment - 2021-10-08 18:03 Sometimes, such conflicts are solved by implementing an API plugin and making both plugins depend on that. However, I wonder if would instead be possible to keep the classes used by the Jira and GitLab plugins separate from each other. Can you post the stack trace of the exception?

Kalle Niemitalo added a comment - 2021-10-11 09:41 - edited I presume RuntimeDelegate in jsr311-api-1.1.1.jar was compiled from https://github.com/javaee/jsr311/blob/jsr311-api-1.1.1/src/javax/ws/rs/ext/RuntimeDelegate.java , which deliberately throws LinkageError. RuntimeDelegate in jboss-jaxrs-api_2.0_spec-1.0.0.Final.jar may have been compiled from https://github.com/jboss/jboss-jaxrs-api_spec/blob/jboss-jaxrs-api_2.0_spec-1.0.0.Final/src/main/java/javax/ws/rs/ext/RuntimeDelegate.java . Both of these call FactoryFinder.find(JAXRS_RUNTIME_DELEGATE_PROPERTY, JAXRS_DEFAULT_RUNTIME_DELEGATE) to locate a RuntimeDelegate implementation by name. It might be possible to isolate these by making gitlab-api-plugin and jira-plugin temporary set a context class loader on the thread, but a new API plugin seems a more maintainable solution.

Kalle Niemitalo added a comment - 2021-10-11 09:49 - edited JENKINS-52171 seems to be the same problem with older plugin versions. JENKINS-60402 is also very similar but it applies to artifactory-plugin rather than jira-plugin.
