and my plugin.yml:

Code:

  main: me.samTB.hello.Main
  version: 1.0
  author: sam
  description: hi!
  commands:
    hello:
      usage: /<command>
      aliases: hi

and my project pic and im using intellij:

plls help

 

@samTB It's because you put spaces in front of your lines in your plugin.yml so change it to this:

Code:

name: hello
main: me.samTB.hello.Main
version: 1.0
author: sam
description: hi!
api-version: 1.16

commands:
    hello:
        usage: /<command>
        aliases: hi

It's a good idea to include API version in your plugins yml, and also when you are putting sub-components into your yml for example your 'hello:' you put 4 spaces for the format.
