Please help me, because I want to give my friend the plugin as soon as possible.
The Java version that needs the plugin is higher than the one being executed.
So for example: On the server of the server is running Java 8, but you have the plugin on Java 12 Programmiert. Then you have to update the server on Java 12.
Thank you. I'll get the rest.
