Solved What does this error message mean when I try to start my Spigot server?

  1. Error: Unable to initialize main class org.bukkit.craftbukkit.Main
    Caused by: java.lang.NoClassDefFoundError: joptsimple/OptionException

    I have all plugins disabled.
    What is joptsimple? If that's the problem, where does it live and how do I get rid of it?

  2. I found the problem!
    When you run BuildTools, you need to point to this file as the server: spigot-1.18.2-R0.1-SNAPSHOT-bootstrap.jar
