Java NullPointerExceptions

hello! I am trying to learn how to code some plugins, but I am having issues with my commands.
i tried adding this (suggested to me by intelliJ because it said there are potential nullpointerexception errors there, I added it but they still exist

this is my command class, I have no idea what could be causing the errors, I tried making the command from this guide: https://www.spigotmc.org/wiki/create-a-simple-command/
and this tutorial:
but both of them give me the same errors

 

i did register it

 

@aPerson12 Does the plugin enable successfully? Check the server log.

 

try:

Code:

getServer().getPluginCommand("test").setExecutor(new Command1());

 

Show us a server startup log.

The require non null is irrelevant you can remove that.

It doesn't make any difference, as he's in the main class so it inherits the necessary methods. Getting the server isn't required and does the same thing anyway.

 

sorry for the late responses i was on a vacation, here is the log: https://pastebin.com/jVrnMYLs

it did not work, it gave me an error again java.lang.NullPointerException: Cannot invoke "org.bukkit.command.PluginCommand.setExecutor(org.bukkit.command.CommandExecutor)" because the return value of "me.improve.testing.TestingPlugin.getCommand(String)" is null
