Maven Build error TOOLS.JAR NOT FOUND IN JRE

I think you need to point JAVA_HOME to a JDK not just a JRE. The JRE is the java runtime environment while the JDK is for development and will contain the compiler and libs required.

If you're getting this in eclipse make sure that Eclipse is pointing to a JDK and Not a JRE.

In Eclipse navigate to Window->Preferences->Java->Installed JRES- Add... Standard VM and point Directory... to a JDK. You'll obviously need to install a JDK if you have not done so.
