Error loading plugin: Unsupported API version 1.2

I'm making a plugin for my server, but when I start the server, it gives me this error:

[Server thread/ERROR]: Could not load 'plugins\CustomServer.jar' in folder 'plugins'

The api-version in the yml file is seen as a number (with 2 decimals). The 0 gets trimmed because the number is round. Thats why the error says you are using api-version 1.2

You should make the api-version a string so it will recognise it as 1.20.

name: CustomServer
version: '1.0'
main: me.user.customserver.CustomServer
api-version: '1.20'
