Broken Plugin

A plugin fails to load because its plugin.yml is invalid. Every Bukkit/Paper plugin needs a valid descriptor, if it is malformed or the jar is corrupt, the server cannot load the plugin.

Hva betyr denne feilen?
plugin.yml describes a plugin (name, main class, version, dependencies). 'Invalid plugin.yml' means that file is malformed or missing required fields, or the jar is damaged, so the server rejects the plugin. 
Invalid plugin.yml
Vanligste årsaker
  • A corrupted or incomplete plugin jar.
  • A malformed plugin.yml (bad YAML or missing fields).
  • A non-plugin jar placed in plugins/ (e.g. a library or mod).
  • An interrupted download.
  • A plugin for a different platform entirely.
Slik diagnostiserer du
  1. Read the log for which plugin/file failed.
  2. Open the jar and inspect plugin.yml for validity.
  3. Confirm the file is actually a Bukkit/Paper plugin.
  4. Compare its size to the official download.
Anbefalte løsninger
  • Re-download the plugin
    Replace a corrupt or partial jar with a fresh official download.
  • Verify it is a plugin
    Ensure the jar is a Bukkit/Paper plugin, not a mod or library.
  • Fix plugin.yml
    If you build the plugin, correct the YAML and required fields.
  • Remove the bad file
    Take any non-plugin jar out of the plugins folder.

At minimum a name, version, and main class. Missing any makes it invalid.

Yes, mods and libraries are not plugins and will fail in the plugins folder.

In the server's plugins/ folder, only on Bukkit/Spigot/Paper-based servers.
