Running ProGuard on OS X: Where is Apple's equivalent to the rt.jar?

I'm running ProGuard to shrink my jar file. One of the parameters it needs is the system's runtime jar. This is at $JAVA_HOME/lib/rt.jar on Sun distributions, but not on Apple's Mac OS X (v10.6 (Snow Leopard) in my case).

Is there an rt.jar for OS X?

Solution

  • It is called classes.jar and it is under /System/Library/Frameworks/JavaVM.framework/Classes
