Try commenting out the use of relocate.

    shadowJar {

        
//        relocate("co.aikar.commands", "com.angel.mc.lib.acf")
//        relocate("co.aikar.locales", "com.angel.mc.lib.locales")
    }

The reason is unknown, perhaps PaperMC already uses co.aikar.commands or co.aikar.locales internally.
