I gues the main reason of problem with 'Duplicate java classes' is problem with Maven. I don't understand why Intellij Idea doesn't see Maven 2.2.1.
from pom.xml: <prerequisites> <maven>2.2.1</maven> </prerequisites> I got message: ERROR] BUILD FAILED [ERROR] Unable to build project 'D:\development\Source\cartapestry01\pom.xml; it requires Maven version 2.2.1 To view full stack traces, please go to the Settings->Maven and check the 'Print Exception Stack Traces' box. But i have correct version of Maven and correct settings in Idea. i try to change it to <prerequisites> <maven>2.0.8</maven> </prerequisites> or remove - nothing result. Sorry, my english isn't good )) -- View this message in context: http://n4.nabble.com/Duplicate-class-found-after-compile-2-1-0-M1-tp788187p932026.html Sent from the AppFuse - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@appfuse.dev.java.net For additional commands, e-mail: users-h...@appfuse.dev.java.net
