Tibor Digana commented on SUREFIRE-1837:
----------------------------------------
[~Enigo]
A perfect motivation is in
https://github.com/mvndaemon/mvnd/issues/103#issuecomment-714448066
There are two exceptions.
As I have understood the comment, both exceptions are about the same problem.
Look, we as Surefire plugin do no cause this problem for sure, otherwise your
project would not download anything at all.
So my recommendation is to go to the Maven mailinglist for developers open a
discussion and put there exactly these two stacktraces.
I have been impressed by the existence of this:
apiguardian-api-1.0.0.pom.lastUpdated (Zugriff verweigert)
LastUpdate?
This means that the artifact is locked and it would expire after some time and
you have to run {{mvn -U ..}}? Or it means that you share one local repository
in your Jenkinsfile for all concurrent builds are two Maven builds attempt to
download and override the artifact?
These are the question to the Maven team and you.
And yes there is one more. If you see these lines, it means that Surefire only
calls the library {{maven-compact:3.0}} and Takari impl consequently. Is it
buggy, or is the above problem?

I don't know. But I know that Surefire calls some external components, that's
all I can say to this issue right now.
