How do I set up Minecraft snapshots?
To play Minecraft snapshots, you have to change the so-called modification in the web interface. This can be done in a few quick and easy steps.
This guide also applies to Minecraft version 1.9.
Changing the modification
Navigate to and to your Minecraft server in the web interface. Then click on the Basic Settings tab, where you will change the modification to Minecraft Snapshots. Once Minecraft Snapshots has been selected, you can also choose a version other than the newest, if necessary. Then save the whole thing and reboot the server.
That's it. The server has now been changed to a Minecraft Snapshot version and now you can start playing. :-)
