Description

One one of my larger integration projects that involves A LOT of version ranges across a broad range of dependencies I'm seeing that Maven locks up resolving dependencies.

I've recently seen this in 3.1.1 but it's happening more and more often under 3.2.1.

It appears that Eclipse Aether is falling into a circular loop somewhere and locking up.

Running with -X -U I can see that Maven/Aether seems to be looking up A LOT of external repositories:
