Eclipse Hang

[shinokamparos]

Hi,

I have a problem with eclipse hanging. Eclipse says it it is invoking
'Maven Project Builder' on tocollege.net in the Progress tab and
building workspace hangs at 25%. I treid switching workspaces and
using the -clean command on startup but to no avail

[Conrad Akier]

I've seen this happen on Windows machines running Eclipse where an
outdated Java JDK was installed or the project needed to be cleaned
via Eclipse's Project >> Clean menu option (I'm not sure if the -clean
command switch you mentioned does the same thing). I would try both of
those first and then an 'mvn clean'.

Although it's an ugly option, ending the java.exe process (via Task
Manager) responsible for building the Eclipse workspace will let the
build proceed.

Sorry I don't have a definitive answer for you, as I do my development
work on a Mac and I haven't seen this issue happen to me there for
awhile. Please report on whether that worked for you or not.

Regards,
-Conrad

Thanks Conrad.

I just got another complaint about this, it would be interesting to
know the relevant Eclipse version etc.

One thought is that if this is the first compile and Eclipse is trying
to do lots n' lots of Maven downloads in the background, it might look
like a freeze.

I'd make sure you can compile from the command line: mvn compile,
since that way it will be easier to see what's happening wrt maven
dependencies.

Hi lads,
Thanks for the help, but I still have this problem. I am running
Eclipse Ganymede. I tried the Project >> Clean menu option, I updated
my jdk to 1.6.0_14. Still no joy.

I complied from the command line with mvn complie and this is the
result:

>mvn compile

Any help would be greatly appreciated.

Brian,
Thanks for trying the mvn compile. Unfortunately it worked! I was
hoping for an error of some kind.

I think the next thing to do is probably to take a look at the eclipse
error logs. I can't remember precisely how to find them. My guess is
that there's a badly behaving plugin somewhere.
