TIP
With the release of Minecraft 1.18, Paper now requires Java 17 to run. If you don't already have Java 17, it's easy to download and install.

Migrating from Vanilla is easy, but there are some differences, namely in world saves. Paper (and CraftBukkit and Spigot) separate out each dimension of a world (nether, the end, etc.) into separate world folders.

Paper will handle this conversion for you automatically. No additional consideration is required.

Paper is a drop-in replacement for both CraftBukkit and Spigot, you don't need to make any changes.

Paper provides runnable server jars directly from our website's downloads page.

Click on the build number to download a file.

To run the server, simply start it up like any other Java application.

Open your terminal, navigate to the saved location, and then run java -Xms2G -Xmx2G -jar paper.jar --nogui. Ensure you replace paper.jar with the name of the jar you have downloaded.

The amount of RAM can be set by changing the numbers in the -Xms and -Xmx arguments. --nogui disables Vanilla's GUI, so you don't get double interfaces when using the command line.

For more advanced Java tuning, see Aikar's Flags.

To configure your server, see the Global Configuration and Per World Configuration pages.

Example

@echo off
java -Xms1G -Xmx1G -jar paper.jar -nogui
pause
