Change the Startup Command
The command displayed at the top of Startup is a read-only preview. It updates when you change the editable variables below it.
- Stop the server cleanly.
- Open Startup.
- Find the exposed variable you need, such as the main JAR or script, server version, additional arguments, or a field named Startup Command.
- Copy the old value somewhere safe.
- Enter the new value. The panel saves it automatically.
- Start the server and read the first Console lines for missing files or invalid arguments.
Available fields depend on the server type.
The base command is controlled by the server template. If the required field is not exposed, contact Haven support instead of trying to work around it.
