Hey guys, I am having trouble making a plugin specifically when I export it to a JAR file and try to run a server to test it. The plugin is just a basic plugin so I can see how it turns out. Here is the log when I try to run it:

I am using Eclipse when I am exporting and I am I select, "Export generated class filed and resources" Before when I selected, "Export all output folders for checked projects" I get a problem with the plugin.yml file not being detected. I am really not sure what the problem is though, help is greatly appreciated!

Hey guys, I managed to figure out the problem. It turn's out the plugin.yml file had a problem like I suspected before. What I forgot to do was write the name of the class in the main part. Instead I only went up to the package.
