How to change JDK version temporarily for mvn

Question

I have used the following command to set the java version temporarily

export JAVA_HOME=/etc/alternatives/java_sdk_1.8.0
export PATH=$JAVA_HOME/bin:$PATH 

but when i run mvn -v I see it's pointing to java 7

so how to change JAVA_HOME temporarily and see the effect in mvn -v ??

Answer 1

I solved by downloading another maven. and running

./mavendir/bin/mvn -v

Now it works fine
