"Move Rapidminer project from one eclipse installation to another"
after not working on the project for a long time, I am finally in the process of finishing my Rapidminer extension to implement a method from computational physics. Now, in order to test it thoroughly, I would like to copy my whole Eclipse project to another machine, ideally on another platform (I did the development on Linux and would like to test everything on Mac OS and / or Windows as well).
So, in Eclipse, I did a File -> Export -> Archive File on the source machine, and then the same with "Import" on the target machine. However, there RM simply fails to run with the error "Could not find or load main class com.rapidminer.gui.RapidMinerGUI". The problem persists whether the target machine runs Linux or Mac OS, as a matter of fact, the Linux target is actually just the same Eclipse version on another user account of my source machine. It seems to me that some configuration is left from the original project that prevents the new project from properly executing RM, but I have so far not found out what exactly is the problem.
Thanks a lot for your help in advance!
