learning plugin development

So I'm learning how to make plugins for bukkit and am doing the basics learning from a youtube video.. But I got this issue that I can't import "JavaPlugins" so I thought I would just add it manually by just writing in the code but it gives errors

 

The building tools from jenkins? Yes I have added that jar file

 

from bukkit jenkins you can download the latest buildtools, it's a jar file
edit:sry for late responses
edit2: sry mb it's from spigot and not bukkit
edit3: where can i download the buildtools from bukkit? i run a bukkit server and prefer it over spiggot

 

@DaHamy The jar file you added was called "(bukkit or spigot)-(minecraft version)" by default, correct?

 

Yeah you can always just go to <Edit by Moderator: Redacted DMCA breaking url> and pick out the version you want; I usually go with spigot over craftbukkit.

Afterwards in eclipse, right click your project and click on add external archives or build path, and find the spigot(version).jar or craftbukkit(version).jar. Once its added (quick tip for eclipse), you can click CTRL-SHIFT-O to auto import (assuming you typed it all in). Once that is done, it will automatically import org.bukkit.JavaPlugin.

Good luck!
