Mac OS X Configure Java Environment Variables & Install Maven

Add java environment variables under Mac

Method 1: In the system-level configuration
terminal, first switch to the root user (sudo -i or sudo su), and then edit the /etc/profile configuration file. After completion, wq! Force save and exit vi.

TudeMacBook-Pro:etc tu$ sudo -i
Password:
TudeMacBook-Pro:~ root# cd /etc
TudeMacBook-Pro:etc root# vi profile

 

# System-wide .profile for sh(1)

if [ -x /usr/libexec/path_helper ]; then
        eval `/usr/libexec/path_helper -s`
fi

if [ "${BASH-no}" != "no" ]; then
        [ -r /etc/bashrc ] && . /etc/bashrc
fi

JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home"
CLASS_PATH="$JAVA_HOME/lib"
PATH=".;$PATH:$JAVA_HOME/bin"
~                                                                               
~                                                                               
:wq!

 

JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home"
CLASS_PATH="$JAVA_HOME/lib"
PATH=".;$PATH:$JAVA_HOME/bin"

#export JAVA_HOME - Note: This line of output can also be omitted

 

Test whether the configuration is successful: to re-login to the terminal.

TudeMacBook-Pro:~ tu$ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home

 


Method 2: Configure for individual users (untested)

#Enter the user's home directory, and then see if there is a .bash_profile file
cd ~
ls -all
#Edit the .bash_profile file (if not, create a new one, command touch .bash_profile)
vim .bash_profile
#In English mode, press the i key to enter the edit mode, enter the following content, and paste your own in the path part
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk/Contents/Home
#After inputting, press esc, then press colon (shift+;), enter wq to save

# Restart the terminal and enter
java -version
#Finish when you see the display

 

Maven installation and configuration

 

1. Unzip the downloaded apache-maven-3.3.9-bin.tar.gz compressed file and create a link (to facilitate the version upgrade of maven).

 

TudeMacBook-Pro:apache tu$ pwd
/Users/tu/software/apache
TudeMacBook-Pro:apache tu$ tar -xvzf apache-maven-3.3.9-bin.tar.gz

 

 

TudeMacBook-Pro:apache tu$ ln -s apache-maven-3.3.9 apache-maven-ln
TudeMacBook-Pro:apache tu$ ls -l
total 16600
drwxr-xr-x  9 tu  staff      306  7 27 16:51 apache-maven-3.3.9
-rw-r ----- @ 1 tu staff 8491533 7 27 16:47 apache-maven-3.3.9-bin.tar.gz
lrwxr-xr-x  1 tu  staff       18  7 27 16:53 apache-maven-ln -> apache-maven-3.3.9

 

2. Configure environment variables: the variable name is M2_HOME , and the variable value is the Maven installation directory; and add %M2_HOME%\bin to the end of the PATH variable value

Method 1, system-level configuration:

The operation is the same as configuring the JAVA_HOME variable. The /etc/profile file after the operation is as follows:

System-wide .profile for sh(1)

if [ -x /usr/libexec/path_helper ]; then
        eval `/usr/libexec/path_helper -s`
fi

if [ "${BASH-no}" != "no" ]; then
        [ -r /etc/bashrc ] && . /etc/bashrc
fi

JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home"
CLASS_PATH="$JAVA_HOME/lib"
PATH=".;$PATH:$JAVA_HOME/bin"

M2_HOME="/Users/tu/software/apache/apache-maven-ln"
PATH=".;$PATH:$M2_HOME/bin"
~                                                                               
~      

 

Method 2: Configure for individual users (untested)

export@juven-ubuntu:bin$ export M2_HOME=/home/juven/bin/apache-maven
juven@juven-ubuntu:bin$ export PATH=$PATH:$M2_HOME/bin

 Add these two lines of commands to the system's login shell script: see if there is a .bash_profile file under ~/, if not, create one, and add these two lines of commands to this file. This way, these configurations are automatically performed each time a terminal is started.

 

At this point, the installation is complete, check the Maven installation with the following command :

TudeMacBook-Pro:~ tu$ echo $M2_HOME
/Users/tu/software/apache/apache-maven-ln
