Hello there

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/alfresco/repo/module/tool/ModuleManagementTool : Unsupported major.minor version 52.0

What could i have done wrong?

The addon is compiled with Java 11 and you are running Alfresco with Java 8.

Thank you but where do i install Java 11, on my local machine or the server? I am accessing the alfresco files using Putty

What is the java version on your server ? Please check the java version. 

Use command to check the java version: java -version

The module management tool "alfresco-mmt.jar" is compiled with JDK 1.8. It seems that, server is using JRE 1.7 or lower version. 

Unsupported major.minor version 52.0 comes when you are trying to run a class compiled using Java 1.8 compiler into a lower JRE version e.g. JRE 1.7 or JRE 1.6.

Simplest way to fix this error is to install the latest Java release i.e. Java 8
