Quick start
-
Install Java 25
FeatherMC needs JDK 25. Check what you have:
Terminal window java -version -
Download the jar
Put the FeatherMC jar in an empty folder and name it
server.jar. -
Start the jar
Open a terminal in that folder and run:
Terminal window java -jar server.jarThe first start asks you to accept the Minecraft EULA in
eula.txt. Do that, start it again, and you are done.
Look for a Done! message in the console. FeatherMC’s own options live in feather.yml in the server root, see the config reference.
