Tibor Digana commented on SUREFIRE-1837:
----------------------------------------
[~Enigo]
The problematic artifact {{apiguardian-api-1.0.0}} is part of JUnit5, right?
If two or more modules are running in parallel, it would be fine to list all of
them which prooves the hypothesis that they attempt to download the artifact
concurrently, lock it which probably cause the issue that the artifact could
not be properly resolved, or the collections are not threadsafe (JMM concept
JSR-133) and the artifact is not visible in the plugin's Thread.
