This is my configuration as follows, you can change the path to yours

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_73.jdk/Contents/Home
export PATH=$PATH:$JAVA_HOME/bin

export M2_HOME=/Users/user/workspace/Tools/apache-maven-3.3.9
export PATH=$PATH:$M2_HOME/bin

After configuration is completed, check which file you configured it in (if it is /etc/profile), and then execute

source /etc/profile
