Command not found - Oh-My-Zsh

I recently installed zsh and oh-my-zsh in my Mac. Now when I try to run a maven command from the terminal, I am getting the following error.

$ mvn install
zsh: command not found: mvn

I have installed Apache maven in /Applications directory. Currently my .zshrc file looks like below.

plugins=(git brew pip mvn mysql-macports python sublime tmux osx)

# ####################
# Maven Config Options
# ####################
export M2_HOME=/Applications/apache-maven-3.3.3
export PATH=$PATH:M2_HOME/bin

As seen above, I appended location of maven installation to the path. But I am still getting errors. Any help is appreciated.

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... .......

Just add:

source ~/.bash_profile

to .zshrc

I had a similar problem after installing oh-my-zsh, but for adb command. Looks like the PATH is shortened when oh-my-zsh is installed. I solved it using following steps.

1. Open the .zshrc file

   sudo nano ~/.zshrc
   

2. Look for # User configuration

   Un-comment the following line:

   export PATH="/usr/bin:/bin:/usr/sbin:/sbin:$PATH"
   

3. Save the file.

4. source ~/.zshrc

Give this one a try for other similar command not found errors.

Try below steps:

Open terminal and run command vi ~/.zshrc

Add below lines in file:

export M2_HOME=/Users/<username>/Downloads/apache-maven-3.6.3 
export PATH=${M2_HOME}/bin:${PATH} 
export PATH

Save file successfully

Open another terminal instance & run command mvn -version

It should work!

• First, as 4ae1e1 pointed out, you missed the $ in PATH=$PATH:M2_HOME/bin
• Second, don't forget to run source ~/.zshrc to take the settings into effect instantly.

As mentioned by @4ae1e1 in his comment, $ have to be added before M2_HOME while referring it in the PATH variable, as follows:

export M2_HOME=/Applications/apache-maven-3.3.3
export PATH=$PATH:$M2_HOME/bin/

Once added, as others suggested, source the ~/.zshrc file.

I faced the exact same issue, this is what worked for me:

1. sudo nano ~/.zshrc

2. add this:

   export PATH=your maven path/apache-maven-3.6.3/bin:/usr/bin:/bin:/usr/sbin:/sbin
   

3. Ctrl+X, select "Y", Press Enter

4. source ~/.zshrc

5. Validate: mvn -version

On macOS, you can add the following to your .zshrc file.

If you have not, download maven from https://maven.apache.org/download.cgi

# Maven
export PATH=/opt/apache-maven-3.8.3/bin:${PATH} # you could have it in a different directory 

To edit .zshrc, you can use an existing text editor such as vim.

$ cd ~
$ vim .zshrc 

Use i to insert the export statements. Once inserted, use escto exit insert mode. Then use :wq! to save and quit the editor. Finally, source the file to see the effects of your new changes.

$ source .zshrc

Now try mvn and you should see something like this.

Step 1: open zshrc file

sudo nano ~/.zshrc

step 2: add 'mvn' in plugins section

plugins=(git zsh-autosuggestions mvn)

step 3: add maven configuration in zshrc file. (make sure your apache maven extract directory. I have extracted in /opt folder)

# Maven Config Options
export M2_HOME=/opt/apache-maven-3.8.4
export M2=$M2_HOME/bin
export PATH=$M2:$PATH

step 4: save the chnages

ctrl+o
ENTER
ctrl+z

Step 5: reload zshrc file

source ~/.zshrc

Step 6: go to terminal and verify

mvn -v

Output :

Apache Maven 3.8.4
 Maven home: /opt/apache-maven-3.8.4
 Java version: 11.0.11, vendor: Ubuntu, runtime: /usr/lib/jvm/java-11- 
 openjdk-amd64 Default locale: en_IN, platform encoding: UTF-8 OS name: 
 "linux", version: "5.4.0-89-generic", arch: "amd64", family: "unix"

vi ~/.zshrc

add source ~/.bash_profile to ~/.zshrc file, after the line source $ZSH/oh-my-zsh.sh

open up a new terminal tab and execute mvn, and it will start working.

I had the same issue. So created .zshrc file and added below in that file. export M2_HOME=/Users/gandharavmehra/Desktop/Development/Tools/apache-maven-3.6.3 export PATH=$PATH:$M2_HOME/bin

after this gandharvmehra@MacBook-Pro ~ % source ~/.zshrc

close the Terminal and open again

gandharamehra@MacBook-Pro ~ % mvn -version Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)

it should work 100 percent

Combining other answers I got adb working on mac and zsh appending these two path lines to .zshrc:

# If you come from bash you might have to change your $PATH.
# export PATH=$HOME/bin:/usr/local/bin:$PATH
# this are for Android Studio adb:
export PATH=~/Android/sdk/tools:$PATH
export PATH=~/Android/sdk/platform-tools:$PATH

Actually, .bash_profile is for /bin/bash shell, for your /bin/zsh shell, the file is called .zprofile, you should do the same thing in .zprofile as in .bash_profile

I have similar issue today with mvn command not found

In my example problem was with incorrect path - I missed one / at the beginning of the path

1. .zshrc before change: export MAVEN_HOME=home/user/Tools/apache-maven-3.6.3 export PATH=$MAVEN_HOME/bin:$PATH
2. good to verify if maven path exists. In my case it was error using command below ls $MAVEN_HOME
3. .zshrc after fix one line export MAVEN_HOME=/home/user/Tools/apache-maven-3.6.3 export PATH=$MAVEN_HOME/bin:$PATH
4. reload .zhsrc source .zshrc
5. mvn command found

If you are running Catalina you will face this problem often.

1. Open your terminal
2. Just copy all your Path variables and create a .zshrc file (touch .zshrc)
3. open it (open ~/.zshrc) and paste them there,
4. save and refresh your .zsrhc file ( source ~/.zshrc).

Install Maven on Mac OS. Download the latest version from the Apache Maven site and select the Maven binary tar.gz file, for example, apache-maven-3.8.4-bin.tar.gz.

Then we extract the archive to our desired location.

Adding Maven to the Environment Path

First, let's open the terminal and switch to the directory where the files were extracted to and then log in as superuser or use below commands with sudo.

Second, we need to remove the tar.gz archive:

> rm Downloads/apache-maven*bin.tar.gz

Third, we have to fix the permissions and switch the Maven contents:

> chown -R root:wheel Downloads/apache-maven* > > mv Downloads/apache-maven* /opt/apache-maven

Then, let's archive the Admin session and add Maven binaries to the path and append:

> exit > > nano $HOME/.profile > > export PATH=$PATH:/opt/apache-maven/bin

Finally, we use Ctrl+x to save and exit from nano.

To load the new setup, let's run:

bash Now, we test if Maven is installed successfully using the command below:

> mvn -version

We are now ready to use Maven on our Mac OS.

Reference : How to Install Maven on Windows, Linux, and Mac

step 1:

vim ~/.zshrc

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

source ~/.bash_profile;

step 3 : (Save changes in Vim)

 :wq!

step 4:(Execution shell)

> source ~/.bash_profile

Best solution work for me

Open Finder-> go to folder /Users/ /usr/local/bin

open .zshrc with TextEdit

.zshrc is hidden file so unhide it by command+shift+. press

delete file content and type

export PATH=~/usr/bin:/bin:/usr/sbin:/sbin:$PATH

and save

now
