The server was installed as a client, not a download, to create a Forge server.
The error "Could not open user_jvm_argr" continues to occur when running "run.sh". 

There are no spaces in the folder and you have also modified "user_jvm_argr".

 

I also installed jdk 18.

But, the same error is displayed

@diesieben07

I'm using Java 17. But only show "could not open user_jvm_args.txt". and I uninstall Java 17 and install Java 18.

But only show "could not open user_jvm_args.txt".  

 

 

@diesieben07

However, if I open the file "run.sh" and specify the exact location of "user_jvm.args.txt", the following error is displayed.

 

"

WARNING: Unknown module: cpw.mods.securejarhandler specified to --add-exports

WARNING: Unknown module: cpw.mods.securejarhandler specified to --add-opens

Error: Could not find or load main class cpw.mods.bootstraplauncher.BootstrapLauncher

Caused by: java.lang.ClassNotFoundException: cpw.mods.bootstraplauncher.BootstrapLauncher

"

When I searched for the error, I knew that I had to buy the game, but I already purchased Minecraft as an official product.

 

 

 

 

And this is my java version.

@diesieben07

Hmm. I can't understand. 

Please give me a detailed explanation and method.

Sorry.

@diesieben07

Thank you for your help.   I am Korean and I didn't understand it properly because of my lack of English.
But thank you for your help until the end.
