JENKINS-55146, one of the issues there is caused by https://issues.apache.org/jira/browse/MJAR-241 . As recommended by Tibor Digana, we should update our plugins. The massive update of plugins was done by Baptiste Mathus recently (e.g. https://github.com/jenkinsci/plugin-compat-tester/pull/97/commits/1299954b4f83f72409d5ad1a4db6efd01c2fbbef ), and Maven JAR Plugin was bumped to 3.1.0. Bumping to 3.1.0 sounds reasonable
Caused by: java.util.zip.ZipException: zip END header not found
The Surefire is not packaging classes in JAR file. It is the responsibility of maven-jar-plugin.
Please see the release 3.1.1 of JAR Plugin we did yesterday, I guess.
After seen deeper, the path is pointing to JDK, this means the file /pct/jdk11-libs/javax.activation.jar and I would say that Oracle or OpenJDK has to be asked.
