Answer 1

I have two Java versions on my Ubuntu server 14.04: java 1.7 and java 1.8.

I have a project that I need to build using java 1.8.

If I check my Java version using java -version

I get

java version "1.8.0_144"

But when I did mvn -version I get:

Java version: 1.7.0_79, vendor: Oracle Corporation

To set the mvn version to java8

I do this:

export JAVA_HOME=/usr/lib/jvm/java-8-oracle/jre/

Then when I do mvn -version I get:

Java version: 1.8.0_144, vendor: Oracle Corporation
