I am using spigot 1.8 because I want to create a minigame server for players from version 1.8 to 1.15. But after I compiled my plugin in IntelliJ IDEA, I put it in the plugins folder, but it didn't seem to work. I thought that maybe the plugin I just compiled didn't include the API I was using for the plugin, so I put the API .JAR file in the same plugins folder and now it works. My question is, how can I include the API and the plugin I am creating in the same JAR file so that I don't have to have two files (1st being the API, 2nd being the actual plugin) in the plugins folder? If this helps, there seem to be an warning while compiling the plugin: "'dependencies.dependency.systemPath' for me.illuminatiproductions.actionbarapi:actionbarapi:jar should use a variable instead of a hard-coded path C:/Users/Hubertas/Desktop/Backup_folder/minecraft/minecraft API's/Spigot/ActionBarAPI-1.5.4.jar @ line 31, column 25"
