Question:

➜ ~ mvn

zsh: command not found: mvn

Answer:

step 1:

vim ~/.zshrc

step 2:(Add at the end of the file)

source ~/.bash_profile;

step 3:(Execution shell)

> source ~/.bash_profile

You can use mvn :

➜  / mvn

[INFO] Scanning for projects...
.......

If you are using zsh now, you may have to use ~/.zshrc rather than the ~/.bash_profile.

Open a new terminal window/tab

I was able to solve this problem. I suspected that some login item made my /bin/bash turn weird. So under someone's recommendation I ran mac in safe mode, and found that everything ran perfectly. Thus, it was a specific login item which screwed up my bash.

For me, it was the yabai window management utility, as there must have been something in the startup script which screwed up my shell.

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.
