Need help with "A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException" #176

Open Myshytricks opened 5 years ago

Myshytricks commented 5 years ago

I downloaded the server files from the "Nature Unleashed" Modpack and it refuses to run. I can run vanilla minecraft from the server.jar but anything having to do with the forge.jar doesnt work.

Try running it with Java 8. Forge 1.12.2 only supports up to JDK 8. Hope this helps :)

If you have more Java version installed on your Server, you can force the server to use a specific version: /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java -Xmx5G -jar forge.jar
