some problem during setting MC server

I want to set a Minecraft server. But it always run into error.

First

Is the environmental problem. Every different mc version demand different JDK. The .bat file contain java need to change the address of corresponding java version.

Second

That start file is .bat, not .jar. Before I aware it, it spend me several hours. (If not exist .bat, you can creat a one and write down

"java address" -Xmx8G -Xms500M -jar forge-.....jar 
pause

)

Third

Click the .bat file and run into error, system will record the problem to txt. And I send to deepseek to search how to solve. Dramatically, deepseek find the correct reason is that my forge version is incorrect. But I don’t trust and border to change.
