Grails Module Classpath in run-app?

Please go to Run Configurations dialog, add a Grails application run
configuration there and specify your Grails module in it. Then hit run.
The classpath should be formed correctly.

'Run Grails Target' in 8.1.3 runs Grails as if it was invoked from
command line. It's an open question, if this is correct. Probably this
will be changed in IDEA 9.

Nope, I tried both 8.1.3 and 9 EAP 10558, with a very simple project: one Grails Module with one Java Module.
In Run Configurations, I selected the Grails Module, but the run-app target still runs with out the Java Module's jar in classpath.I have the screenshot from 9 EAP attached here.

Thank you. The next Maia EAP should contain the fix.

Thanks a lot. Though is it possible to get a fix for IDEA 8.1.x version? We have purchased many IDEA 8 licenses in our company and we have a Grails project just waiting for this bug fix. :-(

Attached is a Groovy plugin version compatible with 8.1.3 which should fix this problem. Please check if it works.

Thank you so much, Peter. It worked well lin 8.1.3.
