Problem Description


I cannot manage to create the server and to install the modpack, I even tried with the provided forge installer (And the right version for the modpack which is RLCraft) but the most I achieve was to run the minecraft without mods, and only with Forge

Reproduction Steps

  • Downloaded the magma version from
  • Sended the .jar and renamed via SFTP to the instance
  • Tryed to start up using the button on the console of the game panel, and getting the error of the java class not found
  • Not being able to run the game


A) Wrong java version is selected in AMP.
B) You’ve got the wrong Forge version selected in AMP. Make sure it has the matching version of Forge selected and that the server jar is set to Automatic.

Please make sure the modpack runs with regular Forge before adding Magma.
Also as a side note, Magma is no longer being maintained and has been forked as a result:
