You might get this error due to couple of reasons. To fix this quickly please follow below steps,

First find the java location. To get a list of your installed Java platforms, run the following command from the terminal:

$ sudo update-alternatives --config java

Now set JAVA_HOME and PATH,

$ export JAVA_HOME=

$ export PATH=$JAVA_HOME/jre/bin:$PATH

Create the symlink

$ sudo ln -s /jre 

When we take your case as a example :

$ sudo ln -s /usr/lib/jvm/java-7-oracle/jre /usr/lib/jvm/java-7-oracle/jre/bin/java

Above command will create the symlink location where the system is trying to find in your issue.

Finally do the

$ mvn --version
