问题
No existing update site is active/up to install the maven plugin version (0.12.1.20110112-1712) for RAD (8.0.4).
A friend of mine already has this version of Maven installed. I tried by copying p2 folder which contains plugin and feature. But doing so, shows the Maven version in the installed software list, but no maven option is available in the RAD.
It will be great if I can find the ACTIVE update url for Maven "0.12.1.20110112-1712".
