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.
|Paper Version||Recommended Java Version|
|1.8 to 1.11||Java 8|
|1.12 to 1.16.4||Java 11|
Migrating to Paper
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.
From Craftbukkit or Spigot
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.

Running The Server
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
disables Vanilla's GUI, so you don't get double interfaces when using the command line.
