I am new to plugin development and ive had a problem in a plugin I want to test were the server says that the plugin.yml is not registering in the server. The logs look like this: Code: > [16:54:15] [Server thread/ERROR]: Could not load 'plugins/Citadel.jar' in folder 'plugins' org.bukkit.plugin.InvalidDescriptionException: Invalid plugin.yml at org.bukkit.plugin.java.JavaPluginLoader.getPluginDescription(JavaPluginLoader.java:160) ~[server.jar:2991-Spigot-018b9a0-f3f3094] at org.bukkit.plugin.SimplePluginManager.loadPlugins(SimplePluginManager.java:144) ~[server.jar:2991-Spigot-018b9a0-f3f3094] at org.bukkit.craftbukkit.v1_16_R3.CraftServer.loadPlugins(CraftServer.java:383) ~[server.jar:2991-Spigot-018b9a0-f3f3094] at net.minecraft.server.v1_16_R3.DedicatedServer.init(DedicatedServer.java:185) ~[server.jar:2991-Spigot-018b9a0-f3f3094] at net.minecraft.server.v1_16_R3.MinecraftServer.w(MinecraftServer.java:809) ~[server.jar:2991-Spigot-018b9a0-f3f3094] at net.minecraft.server.v1_16_R3.MinecraftServer.lambda$0(MinecraftServer.java:164) ~[server.jar:2991-Spigot-018b9a0-f3f3094] at java.lang.Thread.run(Thread.java:748) [?:1.8.0_282] Caused by: java.io.FileNotFoundException: Jar does not contain plugin.yml ... 7 more The layout of my plugin is like this : Code: src: me.peacemango.Citadel: Main me.peacemango.Citadel.KitSelect: Commmands Utils KitSelectUI plugin.yml And my plugin.yml is like this: Code: name: Citadel main: me.peacemango.Citadel.Main description: Adventure map/plugin version: 1.0 author: peacemango commands: Chooseclass: I know it says in the logs that there is no plugin.yml in the plugin but I have triple checked that its in the src and that I have exported with everything selected.
