IntelliJ maven run fails if launched from menu

[mipastgt]

I created a sample Gluon-SingleViewProject with the IntelliJ IDE plugin. When I tried to run this via double-click on Gluon-SingleViewProject->Plugins->gluonfx->gluonfx:run this fails with an error:

This is because the picked maven command is not an executable file. If I manually change the permission to 744 it all works but it is probably not a good idea to fiddle with the permissions of files inside the IntelliJ.app.

I know I can also change this in the Maven settings of IntelliJ but why do I have to do that? Shouldn't the default just work? After all I am not sure whether this is a Gluon or IntelliJ error.
