After compiling with "ant" I get the following NullPointerException (on the splash screen it says "Loading module simulatorProvider")

Please look at the README.MD and follow the installation instructions. Let me know if that worked.

commented

following the instructions does NOT fix the issue...

commented

Please update, build again and let me know, what the thrown RuntimeException message is.

Hi,

the installation comands in the readme are wrong:

instead of
cp -R models/ ~/.BlackBoard
cp -R symbols/ ~/.BlackBoard
cp -R parts/ ~/.BlackBoard
cp -R datasheets/ ~/.BlackBoard
cp -R simulators/ ~/.BlackBoard

it should be:

cp -R models ~/.BlackBoard
cp -R symbols ~/.BlackBoard
cp -R parts ~/.BlackBoard
cp -R datasheets ~/.BlackBoard
cp -R simulators ~/.BlackBoard

commented

I just cloned the repo again and used above commands - works! :)
