To whom it may concern: I've down loaded the maven source from https://svn.apache.org/repos/asf/maven/trunks. M2_HOME=E:\JUtils\maven-2.0.1-SNAPSHOT and E:\JUtils\maven-2.0.1-SNAPSHOT\bin is part of my path. I needed the Maven plug-in development using Ant functionality. Over the weekend I compiled from source with no problem on a different machine. I was able to build Ant plug-ins. Any help would be appreciated. wford I'm getting this error when I run bootstrap.bat.
