Hi everyone

Sorry if this isnt the correct forum to post this question.
I'm new in the JDE, i have been able to build some projects but not this time, i have been looking on the internet but i havent found anything, this is the error code:

java.lang.NoSuchMethodError
at net.rim.a.a.b.do(Unknown Source)

I/O Error: java.lang.NoSuchMethodError
Error while building project

it seems to me that there is a lost library or something but i have no idea. Any help?
