Here you have a list of all the available configurations for the CLI Arguments:

• CLI Arguments
  • ServerJars CLI:
    • --version: Shows the current running version.
    • --help: Shows a list of available commands.
  • ServerJars Settings:
    • --sj.debug: Useful when reporting bugs, it will output more detailed information.
    • --sj.useHomeDirectory: Instead of saving the cached jar files to the folder jar/ it will use the home directory ~/.serverjars/jar.
    • --sj.skipConfigCreation: Skips the creation of a serverjars.properties file using the default values or values from the cli.
    • --sj.serverType={type}: If used with --sj.skipConfigCreation, ServerJars will use this as server type. Defaults to paper.
    • --sj.version={version}: If used with --sj.skipConfigCreation, ServerJars will use this as server version. Defaults to latest.
  • Minecraft Arguments:
    • --mc.*: Use this argument to pass a specific command to the server cli. For example --mc.nogui executes -nogui.
    • --mcdd.*: Like --mc.* passes a specific command to the server cli, but using double dash. For example --mcdd.help executes --help.

Compatibility Mode

If your host or server doesn't allow the usage of custom variables like --mc.nogui, you can add the environment variable SJ_COMPATIBILITY=1 like this:

SJ_COMPATIBILITY=1 java -jar ServerJars.jar

This will pass all non serverjars arguments directly to the cli without the need of using --mc or --mcdd

What about system properties?

System properties can't be controlled, so you're free to use them :D
