Maven error :Perhaps you are running on a JRE rather than a JDK?

Question

I\'ve never worked with Maven before and I am following the instructions here. When I run the command

mvn integration-test -Pamp-to-war

It

Answer 1

This is because of running jre rather than jdk, to install jdk follow below steps

Installing java 8 in amazon linux/redhat

--> yum search java | grep openjdk

--> yum install java-1.8.0-openjdk-headless.x86_64

--> yum install java-1.8.0-openjdk-devel.x86_64

--> update-alternatives --config java #pick java 1.8 and press 1

--> update-alternatives --config javac #pick java 1.8 and press 2

Thank You

Answer 2

Check if /usr/bin has 'javac'. If not you have installed JRE & have to install jdk dev version like "java-1.8.0-openjdk-devel.x86_64"
