We stumbled on the same error after upgrading plugins on Jenkins last week. Search in your Jenkins plugin directory for the jar file starting with the name: guice. The results should only list one version of the guice jar.
In our case it turned out that the Jacoco plugin came with a newer version of guice than the other plugins did, That caused this problem. We downgraded the Jacoco plugin and it worked again (from jacoco 3.2.0 back to 3.1.1 ) Op zondag 23 mei 2021 om 19:55:03 UTC+2 schreef sverr...@gmail.com: > I have upgraded all the plugins, then
