java.lang.NoClassDefFoundError on Grails Run-App

I get the following error when I execute run-app from within STS 2.3. The "Envinronment" tab has the GRAILS_HOME correctly defined. By the error message it seems like the path is getting mangled somehow.

The really strange thing is that this used to work for me in STS 2.3 and then suddenly one day it stopped. Not sure what happened. Any clues?

wenner,

did you update your STS to any nightly build recently? What is the installation directory of STS and Grails? Where is your workspace?

Once if have those details, I can try to re-create.

Hey,

It looks like my error has mysteriously gone away. For reference, answers below.

Did you update your STS to any nightly build recently? No
What is the installation directory of STS and Grails? C:\Program Files\Springsource
Where is your workspace? C:\Users\<self>\workspace

Thanks!

wenner,

glad this is solved but it sounds strange that it fixed itself. Please keep me updated if this comes up again.
