Maven Install on Mac OS X

Question

I'm trying to install maven through the terminal by following these instructions.

So far I got this

export M2_HOME=/user/apple/apache-maven-3.0.3
export M2=$M2_HOME/bin
export PATH=$M2:$PATH
export JAVA_HOME=/usr/java/jdk1.6.0_22

This is probably a stupid question where do you go to find this?

Answer 1

% sudo port selfupdate; 
% sudo port upgrade outdated;
% sudo port install maven3;
% sudo port select --set maven maven3;

— add following to .zshenv -- start using zsh if you dont —
set -a
[[ -d /opt/local/share/java/maven3 ]] &&
    M3_HOME=/opt/local/share/java/maven3 &&
    M2_HOME=/opt/local/share/java/maven3 &&
    MAVEN_OPTS="-Xmx1024m" &&
    M2=${M2_HOME}/bin
set +a

Answer 2

for the ones that just migrated to mavericks - I used the *-ux solution;

1. download maven from apache maven site
2. put in /opt

3. modified .bash_profile and added:

   alias mvn='/opt/apache-maven-3.1.1/bin/mvn'
   export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_21.jdk/Contents/Home

To install Maven on OS X, go to the Apache Maven website and download the binary zip file.

You can then shift the apache-maven-3.0.5 folder in your Downloads folder to wherever you want to keep Maven; however as the rest of the process involves the command line, I recommend you do everything from there.

At the command line, you would run something like:

mv ~/Downloads/apache-maven-3.0.5 ~/Development/

This is just my personal preference - to have a "Development" directory in my home directory. You can choose something else if you wish.

Next, edit ~/.profile in the editor of your choice, and add the following:

export M2_HOME="/Users/johndoe/Development/apache-maven-3.0.5"
export PATH=${PATH}:${M2_HOME}/bin

The first line is important to Maven (and must be a full explcit path); the second line is important to the shell, in order to run the "mvn" binary. If you have a variation of that second line already in .profile, then simply add ${M2_HOME}/bin to the end of it.

Now open a second terminal window and run

mvn -version

which should give output like...

Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 13:51:28+0000)
Maven home: /Users/johndoe/Development/apache-maven-3.0.5
Java version: 1.7.0_40, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.9", arch: "x86_64", family: "mac"

Couple of things to note:

1. If you've installed the Oracle JDK 1.7, then you may find Maven reports JDK 1.6 in the above output. To solve this, add the following to your ~/.profile:

   export JAVA_HOME=$(/usr/libexec/java_home)

2. As some have pointed out, Maven has historically been supplied either with OS X itself, or with the optional Command Line Tools for XCode. This may cease to be the case for future versions of OS X, and in fact OS X Mavericks does not include Maven. Personal opinion: This could be because they are still in beta, or it could be that Apple have taken a look at the latest Thoughtworks Technology Radar, and spotted that Maven has been moved to "Hold".

Answer 4

For those who wanna use maven2 in Mavericks, type:

brew tap homebrew/versions

brew install maven2

If you have already installed maven3, backup 3 links (mvn, m2.conf, mvnDebug) in /usr/local/bin first:

mkdir bak

mv m* bak/

then reinstall:

brew uninstall maven2(only when conflicted)

brew install maven2

Answer 5

brew install maven31 (if you have homebrew)

Answer 6

Alternatively, I recommend installing Homebrew for these kinds of utilities.

Then you just install Maven using:

brew install maven

PS: If you got a 404 error, try doing a brew update just before
