Title: How to upgrade maven in macosx?

See this at Nabble

In mac, maven is laid out as below

ashee-mac:~ amitava$ which mvn
/usr/bin/mvn
ashee-mac:~ amitava$ ls -l `which mvn`
lrwxr-xr-x  1 root  wheel  24 May 25 09:55 /usr/bin/mvn -> /usr/share/maven/bin/mvn
ashee-mac:~ amitava$ ls -l /usr/share/maven
lrwxr-xr-x  1 root  wheel  23 May 28 12:14 /usr/share/maven -> java/maven-2.2.0

So, all I needed is to download the latest version from apache, untar it under /usr/share/java
and update the symlink

ashee-mac:~ amitava$ unlink /usr/share/maven
ashee-mac:~ amitava$ ln -s /usr/share/java/apache-maven-2.2.1 /usr/share/maven

ashee-mac:~ amitava$ mvn --version
