Re: How to uninstall / override previous Maven version on OS X Leopard?

[Unnsse Khan <un...@gmail.com>]

Hi Kalle,

Thanks for the suggestion (I thought about the same solution before  
starting this initial thread on the mailing list)...

The Apache Maven 2.1.0 working as the correct one by placing  
$MAVEN_HOME before /usr/bin in my PATH as follows:

export PATH=$MAVEN_HOME/bin:/usr/local/bin:$PATH:/usr/local/sbin: 
$JAVA_HOME/bin:/opt/local/bin:$PS1:$PATH;

The thing I dislike about this approach is that the previous Maven  
(2.0.6) version still exists on my machine.

Prior to Maven 2.1.0, I had installed the 2.0.6 version by downloading  
the tar.gz (tarball) and then building Maven 2.0.6 by scratch which  
placed the mvn script inside my /usr/bin directory.

Is there a way to truly un-install / wipe the previous mvn (2.06)  
version from my system?

Many, many thanks!

"rm -rf /usr/share/maven"?

Typically, on linux and OS X, I'd expand the maven archive into a directory
(e.g.  /usr/share/maven-2.1.0) and toss in some softlinks:

tar zxvf ~/apache-maven-2.1.0.tar.gz
> mv apache-maven-2.1.0 /usr/share/maven-2.1.0
> mv /usr/share/maven /usr/share/maven-2.0.6
> ln -s /usr/share/maven-2.1.0 /usr/share/maven
>
>
Then, at some point in the future, if I decide I don't want maven 2.0.6
anymore, I wipe it.
