Hi,

I was using Maven 2.2.1 - successfully downloaded repository on my systems when I had Java 1.6. BUT when I moved to Java 1.7 , I am not able to download it again.

NOW I have rollback to java 1.6 but still I am not able to download maven.

[NOTE : I HAVE ALSO TRIED IT WITH MAVEN 3.0.3 AND FACING SAME ISSUE]

I am getting following Build Error

  • Unable to load the mojo
  • java.lang.NoClassDefFound


System has set JAVA_HOME of Java Home directory
