Getting mvn setup to persist on a Mac

I installed Java and Maven on my mac.

The default Java install for mac worked fine and setup my JAVA_HOME etc., all fine.

I installed Maven and followed the instructions on my mac. (http://maven.apache.org/download.cgi)

Again fine...

Until I restarted my mac or created a new terminal.

Then I found the additional secret instructions, which I'd forgotten because I've been away from Unix for so long.

I needed to edit the bash profile.

As explained in this StackOverflow article "mvn-command-not-found-in-osx"

I needed to:

vi ~/.bash_profile

Then add the lines

export M2_HOME=/usr/local/apache-maven/apache-maven-3.2.1export M2=$M2_HOME/binexport PATH=$M2:$PATH

I skipped the JAVA_HOME because when I typed echo $JAVA_HOME in the terminal it had already been exported correctly. If you had to add the JAVA_HOME variable during your installation then you might need to add the export for that in your bash_profile as well.

Remember, with vi, to save the file, press 'esc' and then type ':wq'

esc :wq

I then opened a new terminal, and typed mvn and all was well.
