mvn command not found in OSX Mavrerick

Try following these if these might help:

Since your installation works on the terminal you installed, all the exports you did, work on the current bash and its child process. but is not spawned to new terminals.

env variables are lost if the session is closed; using .bash_profile, you can make it available in all sessions, since when a bash session starts, it 'runs' its .bashrc and .bash_profile

Now follow these steps and see if it helps:

  1. type env | grep M2_HOME on the terminal that is working. This should give something like

    M2_HOME=/usr/local/apache-maven/apache-maven-3.1.1

  2. typing env | grep JAVA_HOME should give like this:

    JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home

Now you have the PATH for M2_HOME and JAVA_HOME.

If you just do ls /usr/local/apache-maven/apache-maven-3.1.1/bin, you will see mvn binary there. All you have to do now is to point to this location everytime using PATH. since bash searches in all the directory path mentioned in PATH, it will find mvn.

  1. now open .bash_profile, if you dont have one just create one

    vi ~/.bash_profile

Add the following:

#set JAVA_HOME
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home
export JAVA_HOME


M2_HOME=/usr/local/apache-maven/apache-maven-3.1.1
export M2_HOME

PATH=$PATH:$JAVA_HOME/bin:$M2_HOME/bin
export PATH

  1. save the file and type source ~/.bash_profile. This steps executes the commands in the .bash_profile file and you are good to go now.

  2. open a new terminal and type mvn that should work.


Solutions above are good but they require ~/.bash_profile. /usr/local/bin is already in the $PATH and it can be confirmed by doing echo $PATH. Download maven and run the following commands -

$ cd ~/Downloads
$ tar xvf apache-maven-3.5.3-bin.tar.gz
$ mv apache-maven-3.5.3 /usr/local/
$ cd /usr/local/bin
$ sudo ln -s ../apache-maven-3.5.3/bin/mvn mvn
$ mvn -version
$ which mvn

Note: The version of apache maven would be the one you will download.


Here is what worked for me.

First of all I checked if M2_HOME variable is set env | grep M2_HOME. I've got nothing.

I knew I had Maven installed in the folder "/usr/local/apache-maven-3.2.2", so executing the following 3 steps solved the problem for me:

  1. Set M2_HOME env variable

M2_HOME=/usr/local/apache-maven-3.2.2

  1. Set M2 env variable

M2=$M2_HOME/bin

  1. Update the PATH

export PATH=$M2:$PATH

As mentioned above you can save that sequence in the .bash_profile file if you want it to be executed automatically.
