[osmosis-dev] Error: Could not find or load main class

[Philipp Hukal]

Hi Evgeniy,

Thanks for your advice!

I was, however, only semi-successful. Several re-installation and version changing attempts on Win8 were fruitless and now I', running Osmosis on Mac without problems... Took me literally 30 seconds to set up.

I would be interested if others have solved it on Windows or know about a solution on the way?

All the best,
Philipp

Sorry, one correction: in bin/ directory I opened osmosis.bat file for edit and changed "plexus-classworlds-2.4.jar" to "plexus-classworlds-2.5.2.jar" in that file.
