When I am trying to set environment variables for mvn in MAC, I am able to set for one session but if I open another terminal and try mvn -version, it doesn't work.
Commands I followed:
vi $HOME/.z_profile
--Added this path in .z_profile file
export M2_HOME=/Users/namangupta/Downloads/apache-maven-3.6.3
export PATH=$PATH:$M2_HOME/bin/
source .z_profile
mvn -version
--Output:
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /Users/namangupta/Downloads/apache-maven-3.6.3
Java version: 15, vendor: Oracle Corporation, runtime: /Library/Java/JavaVirtualMachines/jdk-15.jdk/Contents/Home
Default locale: en_IN, platform encoding: UTF-8
OS name: "mac os x", version: "10.15.7", arch: "x86_64", family: "mac"
After these steps when I open another terminal and try mvn -version I get
zsh: mvn cmd not found and on running printenv the path gets reset. Can anyone please tell me where I am wrong in setting the path?
For MacOS Catolina or higher version, since you have zsh instead of bash, you will need to change the path to another file instead of .bash_profile (used for previous versions) as shown below:
--to open the file
nano ~/.zshenv
--paste the following lines and append path for anything else if you want to, just ensure you enter the proper version u have
export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.8.0_291.jdk/Contents/Home"
export M2_HOME="/Users/namangupta/Workspace/setup_files/mvn/apache-maven-3.8.1"
export PATH=$PATH:$M2_HOME/bin:$JAVA_HOME/bin
--save the file
Ctrl+x, then 'Y' to save and then Enter
--to save the environment variables path
source .zshenv
And you are good to go. To check you can try printenv to check or mvn -version or java -version or echo $PATH
For MacOS Monterey (version 12.5)
-> open ~/.zshenv
->Add following to .zshenv File
export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.8.0_291.jdk/Contents/Home"
export M2_HOME="/Users/namangupta/Workspace/setup_files/mvn/apache-maven-3.8.1"
export PATH=$PATH:$M2_HOME/bin:$JAVA_HOME/bin
->Save file
->mvn -version
This solution worked for me.Thank you :)
You had everything right except the filename - it should be $HOME/.zprofile (with no underscore). That's why it worked when you manually sourced from .z_profile, but didn't work when starting a new terminal.

I just installed Maven via Mac Catalina via command line and mvn -version was showing output. then it went away. Please help.
May be a long post, but in the end you will have a convenient tool to install packages and understanding of how to configure them.
Why maven "disappeared" I have no idea of, so what I would do in this situation:
First of all, I would delete maven manually (find the directory and remove it along with any other files that were setup during maven installation)
Then I would highly recommend using Homebrew - a package manager for macOS
To install Homebrew, open terminal and execute the following command:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Wait for a couple of minutes (a less) until it is installed
Now, that Homebrew is installed, you have a very convenient tool to install stuff on your mac
So, you want to install Maven. You can find Maven on Homebrew
Now you just have to open your terminal again and execute
brew install maven
After a few seconds brew will display the directory it installed Maven in (by default, all Homebrew packages are installed in /usr/local/Cellar/)
You are almost there, now you need to set the environment variable.
As described by Apache, the environment variable needs to be added to the PATH environment variable.
Here I have some uncertainty in terms of what file to use: .bash_profile or zprofile. The confusion is caused by the fact that in latest macOS update (maybe several latest updates) Apple decided to use zsh shell, and so .bash_profile became somewhat functionally equivalent to zprofile. There are many articles on the Internet about what file to use, so you better check them out before proceeding (sorry for not providing links).
On my Catalina 10.15.6 I use .zprofile and everything looks to work perfectly.
Once you decide what file to use, execute the following in the terminal:
nano .zprofile
An editor will open, write this:
export PATH=/usr/local/Cellar/maven/*version*/bin:$PATH
Press Control + X to exit, then Y to save changes and hit Enter to exit the editor
After that you will again be in terminal, where execute:
source .zprofile
To load it. Then close the terminal, open again and check that PATH variable is edited by executing:
env
That's it! Good luck coding!
For MacOs Catalina, below is what worked for me.
Terminal > Vim .zprofile
Add:
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_281.jdk/Contents/Home
export JAVA_HOME
M2_HOME=/Users/username/apache-maven-3.8.1 (This is where my maven folder is.)
export M2_HOME
PATH=$PATH:$JAVA_HOME/bin:$M2_HOME/bin
export PATH
Terminal > source ~/.bash_profile
Restart Terminal > mvn -version
Output:

Did you try executing:
source ~/.zshrc
java is installed at this path
$ which java
/usr/bin/java
mvn -version is giving this error
$ mvn -version
The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
NB: JAVA_HOME should point to a JDK not a JRE
I have tried some of the solutions that were available online, but those don't work for me. Some of those solutions suggested adding
$export JAVA_HOME = /usr/libexec/java_home
or
$export JAVA_HOME = $(/usr/libexec/java_home)
to below files
~/.bashrc
~/.bash_profile
~/.profile
Also when I try to execute one shell command, it shows me error like
Error: JAVA_HOME is not defined correctly.
CARBON cannot execute /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home/bin/java
After struggling for almost a day, I found out that maven is not reading the $JAVA_HOME from either of
~/.bashrc
~/.bash_profile
~/.profile
but it reads $JAVA_HOME from ~/.mavenrc
So finally, when I added
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_141.jdk/Contents/Home
in ~/.mavenrc then got output
mvn -v

Default locale: en_CA, platform encoding: UTF-8
OS name: "mac os x", version: "10.12.6", arch: "x86_64", family: "mac"
To fixed it, update the JAVA_HOME like following :
$ vim .bash_profile
export JAVA_HOME=$(/usr/libexec/java_home)
$ source .bash_profile
Run Maven again :
$ mvn -version
maven reads JAVA_HOME from ~/.mavenrc. Add path for JAVA_HOME to ~./mavenrc and source it.
$ vim ~/.mavenrc
export JAVA_HOME=$(/usr/libexec/java_home)
$ source .mavenrc
On Ubuntu
I faced a similar problem. I configured $JAVA_HOME in /etc/environment
like JAVA_HOME=PATH_TO_JDK for example JAVA_HOME=/home/max/jdk1.8.0_144
Careful with
White space after path declaration JAVA_HOME=/home/max/jdk1.8.0_144[[_NO_WHITE_SPACE_AFTER_DECLARATION]]
Don't put any quotes, e.g. JAVA_HOME="/home/max/jdk1.8.0_144"
Don't put /bin, e.g. JAVA_HOME=/home/max/jdk1.8.0_144/bin <- This is wrong
Please check once there should be no ';' in JAVA_HOME value, if there is semicolon then it would show above error.
I had
JAVA_HOME
set but did not export it and maven was not picking up the correct JAVA_HOME.
Once I exported JAVA_HOME then it got resolved. Do not forget to export JAVA_HOME so that the variable is available to child processes (UNIX* like OS)
export JAVA_HOME=/Library/Java/JavaVirtualMachines/amazon-corretto-11.jdk/Contents/Home
I created a .bash_profile and added the following:
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_101.jdk/Contents/Home
export M2_HOME=/Users/aastha/apache-maven-3.3.9
export PATH=$PATH:$M2_HOME/bin
When I check echo $PATH, I get the following
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
(i.e) maven path is not imported.
and also mvn -version shows: mvn:command not found
When I manually source using source ~/.bash_profile and then do echo $PATH, I am able to see correct mvn path that I have entered in PATH variable in .bash_profile.
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/aastha/apache-maven-3.3.9/bin
mvn -version shows:

My terminal does not source .bash_profile until I manually source it using
source ~/.bash_profile
Note: I created a .profile with the similar content and found out in this case mvn -version shows the maven is installed. And terminal is sourcing .profile automatically.
Why is my terminal not able to source .bash_profile automatically
Could somebody please help?
Thanks in advance :D
How can I make the maven installation permanent? After downloading the apache-maven to /usr/local, I need to print the series of "export" command lines every single time I want to use it. Even after I got the maven to work, maven doesn't work when I restart the terminal.
Added this to ~/.bash_profile:
export M2_HOME=/usr/local/apache-maven/apache-maven-3.2.1/
export PATH=$PATH:$M2_HOME/bin
Command-line:
$ export M2_HOME=/usr/local/apache-maven/apache-maven-3.2.1/
$ export M2=$M2_HOME/bin
$ export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/home
$ export PATH=$M2:$JAVA_HOME/bin:$PATH
$ mvn –-version
Apache Maven 3.2.1 (ea8b2b07643dbb1b84b6d16e1f08391b666bc1e9; 2014-02-14T12:37:52-05:00)

Default locale: en_US, platform encoding: MacRoman
OS name: "mac os x", version: "10.9.3", arch: "x86_64", family: "mac"
After restarting command-line:
$ mvn –-version
-bash: mvn: command not found
Instead of adding export PATH=$PATH:$M2_HOME/bin to ~/.bash_profile, I also tried adding the other export command-lines that sets M2, JAVA_HOME and PATH. This doesn't work.
After moving the application directory to /usr/local
Make a soft link in /usr/bin for universal access of mvn
sudo ln -s /usr/local/apache-maven-X.X.X/bin/mvn /usr/bin/mvn
Verify mvn installation
mvn --version
Since you are using Mac, I recommend that you install Homebrew (a package manager for OS X). Given that, you can install Maven using the brew command, e.g.
$ brew install maven
You need to make /etc/profile.d/maven.sh with the following content:
export M2_HOME=/opt/apache-maven-3.2.1
export M2=$M2_HOME/bin
export PATH=$M2:$PATH
Mac OSX
I found two neat tutorials:
1) mkyong
2) journaldev
Win7 You need to set up environment variables. In Win 7, in Start menu you can type Edit the system environment variables, then click Environment variables. In System variables, add 2 New variables:
M2_HOME=C:\Program Files\Apache Software Foundation\apache-maven-2.2.1 (this one is custom)
M2=%M2_HOME%\bin
After that, among the list of variables, find the one called Path, click Edit, and in the end, after this ; add %M2%;
If you did everything right, and if you have JAVA_HOME set up, then Maven should be permanent.
Do you try putting it in a .profile file instead of .bash_profile?
See What's the difference between .bashrc, .bash_profile, and .environment?
.profile is handled at login, so you need to logout and login for changes to become active.
In the Mac terminal, type below to open text editor
touch ~/.bash_profile
open ~/.bash_profile
Then in the editor, type:
export MAVEN_HOME=~/apache-maven-3.8.1
export PATH=$PATH:$MAVEN_HOME/bin
Close the editor and the contents will be saved. If you check the maven version, you will get response:
nisha$ mvn -version
Apache Maven 3.8.1 (05c21c65bdfed0f71a2f2ada8b84da59348c4c5d)

Now, even if you close and open the terminal, you will be able to get the above output when you hit mvn -version
After upgrading my Mac OSX 10.8 to 10.9, Maven not found in the /usr/share path but its installed in 10.8.
when I try this command:
$ maven -version
got this result
-bash: mvn: command not found
but it worked fine on 10.8? Any idea?
Maven is not installed any more by default on Mac OS X 10.9. You need to install it yourself, for example using Homebrew.
The command to install Maven using Homebrew is
brew install maven
if you don't want to install homebrew (or any other package manager) just for installing maven, you can grab the binary from their site:
http://maven.apache.org/download.cgi
extract the content to a folder (e.g. /Applications/apache-maven-3.1.1) with
$ tar -xvf apache-maven-3.1.1-bin.tar.gz
and finally adjust your ~/.bash_profile with any texteditor you like to include
export M2_HOME=/Applications/apache-maven-3.1.1
export PATH=$PATH:$M2_HOME/bin
restart the terminal and test it with
$ mvn -version
Apache Maven 3.1.1 (0728685237757ffbf44136acec0402957f723d9a; 2013-09-17 17:22:22+0200)

Default locale: de_DE, platform encoding: MacRoman
OS name: "mac os x", version: "10.9", arch: "x86_64", family: "mac"
brew install maven
Please ensure that you've installed the latest Xcode and Command Line tools.
xcode-select --install
Download Maven from here.
Extract the tar.gz you just downloaded to the location you want (ex:/Users/admin/Maven).
Open the Terminal.
Type " cd " to go to your home folder.
Type "touch .bash_profile".
Type "open -e .bash_profile" to open .bash_profile in TextEdit.
Type the following in the TextEditor
alias mvn='/[Your file location]/apache-maven-x.x.x/bin/mvn'
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdkx.x.x_xx.jdk/Contents/Home/
(Make sure there are no speech marks or apostrophe's)
8. Make sure you fill the required data (ex your file location and version number).
Save your changes
Type ". .bash_profile" to reload .bash_profile and update any functions you add. (*make sure you separate the dots with a single space).
Type mvn -version
If successful you should see the following:
Apache Maven 3.1.1
Maven home: /Users/admin/Maven/apache-maven-3.1.1

OS name: "mac os x", version: "10.9.1", arch: "x86_64", family: "mac"
This solution could seem very long, but it's not. I just included many examples so that everything was clear. It worked for me in Mavericks OS.
Note: I combined and edited some of the answers shown above, added some examples and format and posted the result, so the credit goes mostly to the creators of the original posts.
Download Maven from here.
Open the Terminal.
Extract the file you just downloaded to the location you want, either manually or by typing the following lines in the Terminal (fill the required data):
mv [Your file name] [Destination location]/
tar -xvf [Your file name]
For example, if our file is named "apache-maven-3.2.1-bin.tar" (Maven version 3.2.1) and we want to locate it in the "/Applications" directory, then we should type the following lines in Terminal:
mv apache-maven-3.2.1-bin.tar /Applications/
tar -xvf apache-maven-3.2.1-bin.tar
If you don't have any JDK (Java Development Kit) installed on your computer, install one.
Type "java -version" in Terminal. You should see something like this:
java version "1.8.0"
Java(TM) SE Runtime Environment (build 1.8.0-b132)
Java HotSpot(TM) 64-Bit Server VM (build 25.0-b70, mixed mode)
Remember your java version (in the example, 1.8.0).
Type "cd ~/" to go to your home folder.
Type "touch .bash_profile".
Type "open -e .bash_profile" to open .bash_profile in TextEdit.
Type the following in TextEdit (copy everything and replace the required data):
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk[Your Java version].jdk/Contents/Home
export M2_HOME=[Your file location]/apache-maven-[Your Maven version]/
export PATH=$PATH:$M2_HOME/bin
alias mvn='$M2_HOME/bin/mvn'
For example, in our case we would replace "[Your Java version]" with "1.8.0" (value got in step 5), "[Your file location]" with "/Applications" (value used as "Destination Location" in step 3) and "[Your Maven version]" with "3.2.1" (Maven version observed in step 3), resulting in the following code:
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0.jdk/Contents/Home
export M2_HOME=/Applications/apache-maven-3.2.1/
export PATH=$PATH:$M2_HOME/bin
alias mvn='$M2_HOME/bin/mvn'
Save your changes
Type "source .bash_profile" to reload .bash_profile and update any functions you add.
Type mvn -version. If successful you should see the following:
Apache Maven [Your Maven version] ([Some weird stuff. Don't worry about this])
Maven home: [Your file location]/apache-maven-[Your Maven version]
Java version: [You Java version], vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk[Your Java version].jdk/Contents/Home/jre
[Some other stuff which may vary depending on the configuration and the OS of the computer]
In our example, the result would be the following:
Apache Maven 3.2.1 (ea8b2b07643dbb1b84b6d16e1f08391b666bc1e9; 2014-02-14T18:37:52+01:00)
Maven home: /Applications/apache-maven-3.2.1

Default locale: es_ES, platform encoding: UTF-8
OS name: "mac os x", version: "10.9.2", arch: "x86_64", family: "mac"
For me trying above techniques did work so I opened .bash_profile file and added following line in new line to connect to maven using short cmd :
alias mvn=/opt/apache-maven-3.6.3/bin/mvn
Restart your terminal and hit mvn clean install cmd
I am not allowed to comment to pkyeck's response which did not work for a few people including me, so I am adding a separate comment in continuation to his response:
Basically try to add the variable which he has mentioned in the .profile file if the .bash_profile did not work. It is located in your home directory and then restart the terminal. that got it working for me.
The obvious blocker would be that you do not have an access to edit the .profile file, for which use the "touch" to check the access and the "sudo" command to get the access
touch .profile
vi .profile
Here are the variable pkyeck suggests that we added as a solution which worked with editing .profile for me:
export M2_HOME=/apache-maven-3.3.3
export PATH=$PATH:$M2_HOME/bin
For me I had a AdoptOpenJDK 8 installed, instead of SE JDK 8. For which it was not able to recognize JAVA_HOME or mvn commands.
Check your java_home
/usr/libexec/java_home -V
and use JAVA SE SDK if it is different.
Then follow the above steps to install maven and check again
