Maven Build Broken on Linux but not on Mac OSX

[#1]

We have an AEM 6.3 project. Most of our devs are on windows and mac. We are trying to replicate the building of the package on ubuntu 16.04 but the build is getting an error.

On an example linuxmachine where the package builds successfully:

Maven config of our Ubuntu machine

JDK is installed on this machine:

Our error:

We noticed:  JAVA_HOME should be pointed to JDK and not to JRE; Java home: /usr/lib/jvm/java-8-oracle/jre?

[#3]

That's a great point, however, I am not finding any specific documentation for where that should point to.

which javac returns

which cannot be set as $JAVA_HOME

Most ppl point to the installed JAVA JDK - my JAVA_HOME --

C:\Program Files\Java\jdk1.8.0_111

For those reading this thread - here is a great overview of setting up an AEM DEV environment:

We followed these instructions to install the JDK

It says: "There is another default Java installation called the JDK (Java Development Kit). The JDK is usually only needed if you are going to compile Java programs or if the software that will use Java specifically requires it."

Set your Java HOME to Java JDK - make sure you install version 8 from Java download page.

Thanks for the help so far.

I went to the Oracle site, downloaded java 8 and installed it. My new Maven Output

$mvn -version

I deleted my .M2 folder and tried again to build the package

Unfortunatly I get the same error

Set the Java HOME to: /opt/jdk/jdk1.8.0_162
