Monkey Zone cannot launch

Hi JMonkeyEngine,

Thanks for the amazing work on the engine. I plan to make something fun after reading through the docs. Though my first attempt is a little frustrated. I downloaded fresh SDK, and SVN checkout the monkey zone trunk. When running the clientMain class, I got this error:
Exception in thread “LWJGL Renderer Thread” java.lang.LinkageError: Version mismatch: jar version is ‘23’, native library version is ‘21’
at org.lwjgl.Sys.(

Can you help to solve this?

Somehow theres an old binary somewhere… Try deleting all dlls from the project folder so it re-extracts.

Thanks Normen for the prompt reply.

I’m using mac, so I think those jars need to be deleted? In the project folder ./lib there’s only one cai-nmgen-0.1.2.jar, and the library panel says jME3-* jars are global libraries from /Applications/, etc.

I also tried to delete /User/xxx/Application Support/jmonkeyengine and no luck.

What else should I remove?


More info: mac mountain lion, SKD version is 3.0 RC2

:? No need to delete random files, just the DLL files in the project folder as I said, thats .jnilib on mac.
