ProvisionException when downloading Groovy plugin for Eclipse

Question

This is not really a coding question however I need some help to get it running :-)

Using Eclipse 4.2 (Juno) I have added http://dist.springsource.org/release/GRECLIPSE/e4.2/ to the list of available software to download the latest Groovy plugin.

However I get the following error message after some time:

eclipse.buildId=M20130204-1200
java.version=1.7.0_21
java.vendor=Oracle Corporation
BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=de_DE
Command-line arguments:  -os win32 -ws win32 -arch x86

Do you experience the same?

Looks like a proxy/firewall issue. Make sure to go to Preferences -> General -> Network Settings and specify your proper settings there.
