  • Don't install Maven 2 anymore http://maven.apache.org/maven-2.x-eol.html Download maven from http://maven.apache.org/download.html – khmarbaise May 29 '15 at 07:34

Instead of doing that you can copy maven source and point M2_HOME to that location.

I came across similar problem and after adding below environment variables it worked for me

export M2_HOME=<your apache-maven installation path up to bin>
export JAVA_HOME=<your Java installation path up to bin>

Also modify your PATH variable

  • M2_HOME is not neccessary. Only the bin folder of the appropriate maven installation (something/apache-maven-3.0.5/bin) must be in the path. – khmarbaise May 29 '15 at 07:35
