Hi,

Please follow the IntelliJ IDEA guide at: http://docs.robovm.com/getting-started/intellij.html

You need to run IDEA with Java 7.

Hth,
Mario

[Christopher Graham]

OK, problem solved. An IntelliJ upgrade trashed the required info.plist JVM version I'd specified previously.

[Alden Torres]

Is there a particular reason for this? Working with IDEA+JRE1.7+ is a problem if you care about the IDE font rendering. Is it anything we can do to get this plugin working with IDEA+JRE1.6? or just wait until JDK 1.9?

Thanks

[Mario Zechner]

The problem is that RoboVM is written using Java 7. Back-porting to Java 6 is a problem at this point due to the large amount of Java 7 in the code base. The IntelliJ RoboVM plugin is very young and we weren't aware of the Java 7 issues in IDEA when the compiler was written.

 JetBrains themselves have now stopped supporting Java 6 with IntelliJ IDEA 15 EAP, bundling a new custom JDK 8 (the previous bundled JDK still had issues).

I'm afraid we'll have to wait this one out until IDEA 15 is released.

[Alden Torres]

Thanks for your comments. Now I understand, it's no only about the plugin, is that the plugin use (and I suppose load) code for the RoboVM compiler and all is written in Java 7. I will take a look at IDEA 15 EAP.

Regards
