How to debug stuck maven dependency download in Bitbucket Pipelines

Question

In a Bitbucket Pipeline build, I have a maven step which downloads a dependency from an SSH Maven respository operated by me.

The dependency is downloaded via scp.

When Maven tries to download it (via wagon ssh), it remains stuck.

I have added a test script as a step which just download via scp the pom.xml in order to check for autenthication problems and alike, but it is working fine (it connects, and download the pom.xml w/o errors).

Any hint about debugging it?

By using:

- export MAVEN_OPTS="$MAVEN_OPTS -Djavax.net.debug=ssl"

I spotted an exception in some TLS code which suggested me that it had to be a wagon version issue.

And indeed upgrading the wagon extension to 3.3.4 solved the problem.
