Setup a SpongeForge Mixin plugin

Hi, I want to setup a plugin which can use Mixin and which have SpongeAPI, SpongeCommon, SpongeForge and Minecraft’s sources in the classpath. I would like to be able to run and debug the server from my IDE. I searched many times on the forums but it’s still unclear for me. I don’t really know what I should do. I’m using Eclipse and Gradle but I will try Intellij if needed. Can someone help me ?

Thanks, I was just searching at the wrong place :frowning:

EDIT: I can’t run the server https://pastebin.com/WH7gfZnU
EDIT2: @Zidane helped me to fix the problem, it was a bit more complex than just following the documentation :sweat_smile:
