Hello Papapara
What you can do to track down your problem:
As you already did, looking at the current stacks dumps of eclipse is a good
thing.
The one stack that we see in your e-mail, tells me, that in thread "Worker-0"
there is an open tcp-connection to the "other side" and that it tries to read
data. Maven/Wagon downloads artifacts.
One important note on that:
If you only look at such one Thread Dump, you can NOT automatally conclude that
the artifact download does not work. It could be, that the system has to
download, say, 100 artifacts, and each download takes 1 second (internet
delays).
So, it's good also to watch progress (like: turning on debug logging of
m2eclipse in its preferences page.) and generating Thread Dumps more than once,
and comparing those dumps: do you see different stacks etc.
As mentioned in my previous posting shortly, I used "netstat -a" or "netstat
-ao" (on windows) to understand whicht TCP connections are currently open. So
you can see who "the other side" is. So you can track down the one, that is
perhaps not sending the expected data.
One more thing to try, is: Do the same thing NOT in (m2)-eclipse, but on the
command line, and see if it works there.
Hope it helps.

Betreff: Re: AW: [m2eclipse-user] Maven classpath container refresh job hanging
Thanks, Eugene and Gerhard,
this error occurs also when I connect to the remote repository directly from
my machine so the internal repository configuration is not an issue in this
case.
Here is my thread dump - maybe this will give you more clues:
