Going from IntelliJ IDEA UI 9.0.4 to UI 10.0.2 we have encountered a problem: in our Maven (2.0.9) based project with many Grails (1.1.1) plugins the inter-plugin dependencies are lost.
Applying inter-plugin (module in IntelliJ speech) dependencies via Project Settings-Module Selection-Dependencies-Add Module-Dependency-Ok fails. After revisiting the dialog the previously selected dependencies are gone.
IDE settings have not been imported from old IDE verstion to new. The project has been simply opened. Saving the project in a directory based format did not help to solve the problem.
This is a blocker for us, the code is full with "Cannot resolve symbol" errors.
I'd be thankful for any hint regarding if this is a know issue and how to fix.
