Build exception: Internal error: (java.io.EOFException) null

Hi guys,

I just mavenized a Flex project, I can build and run the application using maven commands.

The project is well imported into IntelliJ, no errors.

When I rebuild / make / compile thru IJ, I have this [1], any idea why and how I can get ride of this ?

Thanks,

-Fred
