Plugin Errors
Troubleshoot and fix plugin errors on your Cafora Minecraft server.
Plugin errors can range from minor annoyances to server-crashing problems. This guide covers common plugin issues and solutions.
Types of Plugin Errors
Startup Errors
Plugin fails to load when the server starts:
- Missing dependencies (other plugins required)
- Wrong server software version (Bukkit vs Spigot vs Paper)
- Incompatible Minecraft version
- Corrupted plugin JAR file
Runtime Errors
Plugin loads but throws errors during gameplay:
- NullPointerException (accessing something that does not exist)
- ClassCastException (type mismatch)
- Configuration errors
- Database connection failures
Reading Plugin Errors
A typical plugin error in the log looks like:
[Server thread/ERROR]: Could not pass event PlayerJoinEvent to PluginName
java.lang.NullPointerException: Cannot invoke method because object is null
at com.example.plugin.Listener.onJoin(Listener.java:42)The last line shows the exact class and line number where the error occurred.
Troubleshooting Steps
Identify which plugin is causing the error from the log.
Check that the plugin is compatible with your server version.
Verify all dependencies are installed.
Review the plugin configuration for errors.
Try a clean install: remove plugin data, reinstall the JAR.
Contact the plugin developer if the issue persists.
Download plugins only from trusted sources like SpigotMC, Paper Hangar, or Modrinth. Unofficial downloads may contain malware or be outdated.
