I've createt an Forge Server on my Mac.

 

I'm able to start the server with the highlighted .jar-file and it works just fine.

 

My problem is, when I try to start my server with this command file:

... it refuses to start. I always become this error message: https://pastebin.com/0ykQFFYV

 

I'm fine with starting the server with the .jar file, but I wan't to locate more RAM to the Server. Is there a way how I can fix the start file or locate more RAM somehow different?

Thanks in advance for your replies!

Make sure it is using Java 8. Add a java -version to your shell script to have it output the java version to make sure.

@Ugdhar how can I do this?

I would say add a line "exec java -version" (without the quotes) right before the line that starts your server, and see what it tells you for a version before the error message that shows up.

 

*edit: please note, I don't use a mac whatsoever, so I'm not 100% sure how things work, but I am very familiar with linux.

Sorry that I'm so stupid, but what should i write exactly?

#!/bin/bash
cd "$(dirname "$0")"
exec java -Xmx1G -Xms4G -jar forge.jar
exec java -version

Should I just use this and replace the term version with my version.

 

On Windows, there is simmalar file wich includes the file path to java. On Mac this would be this /Users/jakob/Library/Application Support/minecraft/runtime/jre-x64/jre.bundle/Contents/Home/bin/java

Does that help you in any way to help me?

No, use -version, exactly as you have it up there, it should print out what version of Java it is using.

Ok, even with the new file, I get the same error message

what if you put the java -version line first, I know it's not going to fix it, I just want to know what version of java your script is trying to use. and it should output it.

It needs to be java 8, and just having java 8 does not mean that's the one it's using.

Yes I had understodd that it wouldn't fix my prob. It is great that you take so much time to figure out what my problem is.

This is what happens if I put the -version term first.

 

PS: I tried to start the "Vanilla" minecraft_server.1.12.2.jar with the file and it worked. Don't know why the forge server doesen´t starts

Your issue is it's trying to use Java 14, and you need Java 8 for forge.

I believe someone said the reason is because one of the libraries required by forge still targets Java 8.

Have you any idea how I can fix this?

You need to install Java 8, and then more than likely tell your system to use that as the default java, or directly specify the java you wish to use when you launch the server.

As I don't have nor use a mac, I'm not 100% sure how to tell you how to proceed with doing that, google probably knows!

Thank you a lot. I'll see how I get on with this. I now have kind of a starting pointt
