How do I use a custom JAR file?

If you have a custom .jar file you want to use for your server don’t worry, we support that too!

Step 1. Download the custom .jar to your computer

Step 2. Rename the file to “custom.jar” (rename it to customjava7.jar or customjava11.jar if you need to launch with Java 7 or 11, respectively) Note that if you cannot see file extensions it should not say .jar at the end of the filename.


Step 3. Stop your server


Step 4. Upload the custom.jar or customjava7.jar/customjava11.jar to your server’s main directory in the File Manager in Multicraft or an FTP Client which can be configured here.


Step 5. In the Jar Selection Menu click on the “Custom” label in the launcher panel and select the option matching your custom jar file name.


Step 6. Click "Save"

Step 7. Start your server
