Find Minecraft source code permissions?

Because I'm currently building my own server Just for fun and have some nice plugins in prospect, for which I unfortunately have no permissions but the source code. Now I wanted to ask, since I'm not very familiar with programming but know that the permissions are in the source code, whether someone knows how I get the permissions out of there? P.S which Bukkit version do I have to add so that everything is not yellow? LG

There's no general answer to this. Yellow markings are only warnings, not errors. If you only want to read out the persmissions, these are often set up differently depending on the program.

But in Spigot and Bukkit you can search for the lines "hasPermissions (" ")". The brackets then indicate which permissions are required for this.
