Monkey Zone cannot launch

Troubleshooting SDK
1

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.(Sys.java:118)
at com.jme3.system.lwjgl.LwjglAbstractDisplay.run(LwjglAbstractDisplay.java:206)
at java.lang.Thread.run(Thread.java:680)

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/jmonkeyplatform.app/Content/Resources/jmonkeyplatform/jmonkeyplatform/libs/jME3-core.jar, etc.

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

What else should I remove?

Thanks,

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.
