Hello, I have a distant server on which i store things and launch servers for a variety of games like ARK or in this case minecraft. I use craftbukkit to do so, and wanted to have a bit more fun by adding mods so i followed some tutos and the step by step wiki page https://bukkit.gamepedia.com/Installing_Plugins But here i am with the following error on most of the mods I want: "org.bukkit.plugin.InvalidDescriptionException: Invalid plugin.yml" "Caused by: java.io.FileNotFoundException: Jar does not contain plugin.yml" So i went on the forum but only found people who were trying to make their own plugins and not creating the jar file correctly from the IDE. But that is not my case, i just downloaded some jar files from the bukkit plugins page and SFTPed them on my server's plugin folder. Did I make somthing wrong ? Did I missed a step somewhere ? Maybe my browser did not get the entire jar file... Right now i am out of ideas to explain and pretty sure i am an idiot trying to find something that is right in front of me... PS: non-exhaustive list of plugins i tried to add : Galacticraft Draconic Evolution Blood Magic Applied Energetics PPS: I tried to download World-Edit and opened it with winrar and the plugin.yml is in there so maybe it is only a problem for some mods and i was unlucky
