@Baptiste, so I guess your vote is actually +1 to remove it from
documentation, right?
M2_HOME is automatically set by the shell or batch script.
The M2_HOME variable is here used to easily switch between different Maven
distributions. But with this name this can indeed cause
NoClassDefFoundErrors.
For the majority of the community it's not interesting to have multiple
versions of Maven and to switch often.
So this M2_HOME might be confusing. Instead just add
apache-maven-3.x.x/bin to your path.
You have my +1 for this change.
Also, there's no need to add JAVA_HOME/bin to the path. Maven picks it up
as an environment variable, it won't scan the path searching for the java
executable. So I'd like to see that removed as well.
thanks,
Robert

-1 it's a problematic variable, removing it is a good idea IMO, and
changing mvn version is indeed just a matter of updating your path.
I've been hit many a time by an updated PATH pointing to a different mvn
version than the one referenced by M2_HOME, which ends with
NoClassDefFoundError or something like that IIRC.
That's why I've personally been advising maven users I encounter to never
ever set that variable for years.
Cheers

+1, very useful but I guess it doesn't require the name M2_HOME.
