Extract the distribution archive, i.e. apache-maven-3.2.3-bin.tar.gz to the directory you wish to install Maven 3.2.3. These instructions assume you chose /usr/local/apache-maven. The subdirectory apache-maven-3.2.3 will be created from the archive.
In a command terminal, add the M2_HOME environment variable, e.g. export M2_HOME=/usr/local/apache-maven/apache-maven-3.2.3.
Add the M2 environment variable, e.g. export M2=$M2_HOME/bin.
Optional: Add the MAVEN_OPTS environment variable to specify JVM properties, e.g. export MAVEN_OPTS="-Xms256m -Xmx512m". This environment variable can be used to supply extra options to Maven.
Add M2 environment variable to your path, e.g. export PATH=$M2:$PATH.
Make sure that JAVA_HOME is set to the location of your JDK, e.g. export JAVA_HOME=/usr/java/jdk1.7.0_51 and that $JAVA_HOME/bin is in your PATH environment variable.
Run mvn --version to verify that it is correctly installed.

Examples:

$ java -jar jd-cli.jar HelloWorld.class
Shows decompiled class on a screen

$ java -jar jd-cli.jar --skipResources -n -g ALL app.jar
Decompiles app.jar to app.src.jar; It doesn‘t copy resources to the output jar,
the decompiled classes contain line numbers as comments and the jd-cli prints
the most verbose debug information about decompilation

$ java -jar jd-cli.jar myapp.jar -od decompiled -oc
Decompiles content of myapp.jar to directory named ‘decompiled‘ and also on a
screen
