Description

Maven 3 uses the environment variable M2_HOME to point to it's installation directory. This variable should be replaced by M3_HOME to allow users to have parallel installations of Maven 2 and Maven 3 without any special handling of the environment variable M2_HOME.

If this is done, it may break scripts etc that rely on M2_HOME variable.

So any such change should be well publicised as an incompatible change.

If it can be done in such a way that M2_HOME still works when using Maven 3, so much the better.

Can this be added such that M3_HOME & M3 are the default, if neither are set it falls back to M2?

This is exactly that I thought how it should be handled.

And why do you set the env variable at all?
