Hi gals and guys!

I’m using a Leap Motion for a project and have two libraries using the same “LeapJava.jar” file, so whenever I try to run the sketch it throws: “Duplicate libraries found for com.leapmotion.leap”

Is there a way I can circumvent this issue, or perhaps join two libraries in one? Or will I just have to sacrifice one library for the other?

Thanks in advance!

I think you should be able to rename one of the libraries, remember to use the naming rules and to use the new name in your sketch.

Thanks, Paul. Will check out the naming rules and such.  
Have a nice Sunday!

Its quite simple, just no spaces allowed and I think no “-”
