While using the Nexus Platform plugin for Jenkins using Java 11 there’s an error configuring a Nexus Repository Manager 3.x Server. Upon clicking “Test connection” there’s an error requiring JAXB-API. Reverting the Jenkins instance back to Java 8 using the same configuration works properly.
Jenkins 2.235.5 - Java openjdk version “11.0.9”
Nexus Platform Plugin 3.9.20201109-154552.99ba8b9
Nexus OSS 3.28.1-01
While investigation this error I came across this PR on github adding Java 11 support by adding the missing JAXB dependencies, but it was closed and never merged.
