Maven Install on Mac

On Mac OS X 10.6, you will likely find maven already installed.

To check:

> mvn --version

> whereis mvn

/usr/bin/mvn

> ls -l /usr/bin/mvn

lrwxr-xr-x  1 root  wheel  24 Feb 26  2010 /usr/bin/mvn -> /usr/share/maven/bin/mvn

Most likely, your mvn is linked to /usr/share/maven/bin/mvn

> ls -l /usr/share/maven

lrwxr-xr-x  1 root  wheel  23 Oct 13 18:14 /usr/share/maven -> java/apache-maven-2.2.1

However, you may want to install a particular version of maven rather than the version 

Simply download maven at http://maven.apache.org/download.html

uncompress the file to get apache-maven-2.2.1 folder.  place that folder inside /usr/share/java/ folder.  

Remove the original /usr/share/maven link and link it to the new maven version. 

> sudo rm /usr/share/maven

> sudo ln -s /usr/share/java/apache-maven-2.2.1 /usr/share/maven

To check that things are done correctly:

> ls -l /usr/share/maven

> mvn --version

Javafx 2.0

Javafx 2.0 beta is released.  GA is scheduled in Q3 2011.

The big change is they finally get rid of javafx script.  Javafx will now uses Java as its language.
This is a welcoming change.  Quoting Javafx PM in oracle: "most java developers want to use the same language to develop their UI".
Potentially, this enables developers to build web applications where frontend and backend use the same language.
