Re: [m2e-users] eclipse hanging after installing m2e

[Igor Fedorenko <igor@xxxxxxxxxxxxxx>]

m2e needs to run a very short-lived external process process to query
operating system environment and for some reason that fails. This is
exactly the same code used by Maven, so this is rather puzzling.

Can you confirm that you can successfully use maven 3.0.2 on command line?

What operating system are you running?

Can you think of any particulars of your environment that would prevent
m2e to execute an external process?
