I’m completely stumped and I’m sorry in advance if this is a compete newb error. I can run SpongeVanilla in my IDE, elipse, as well as spongecommon. When I load Sponge for forge, eclipse can’t find the main class:
Error: Could not find or load main class org.spongepowered.mod.SpongeCoremod
Go into the Run Configurations dialog. In Sponge_Server and Sponge_Client go to the Arguments tab and change -Dfml.coreMods.load org.spongepowered... to -Dfml.coreMods.load=org.spongepowered.... There is a missing = sign.
Now that i look at it, the README file is correct. While setting up, the Run configs were there when I went to add the server and client, so I had skipped that step and thus got the args with the missing “=”.
