PacketEvents Troubleshooting

If you encounter errors when enabling the Typewriter plugin, such as java.lang.NoClassDefFoundError related to io.github.retrooper.packetevents, this could be due to an incompatible version of the PacketEvents plugin.

Error Message​

An example of the error message you might see:

[12:41:54 ERROR]: Error occurred while enabling Typewriter v0.5.1 (Is it up to date?)
java.lang.NoClassDefFoundError: io/github/retrooper/packetevents/bstats/Metrics$CustomChart
        at me.gabber235.typewriter.entry.entity.EntityHandler.initialize(EntityHandler.kt:23) ~[typewriter (5).jar:?]
        at me.gabber235.typewriter.Typewriter.onEnableAsync(Typewriter.kt:121) ~[typewriter (5).jar:?]

Cause of the Issue​

This error occurs because the installed version of PacketEvents is not compatible with the version of Typewriter you are using. Typewriter v0.5.1 requires PacketEvents version 2.5.x. Using a newer version of PacketEvents can cause compatibility issues due to changes in the API.

Steps to Fix​

  1. Remove the current PacketEvents plugin from your server's plugins folder.

  2. Download PacketEvents version 2.5.0 via this url.

  3. Place the downloaded PacketEvents jar into your server's plugins folder.

  4. Restart your server to apply the changes.

Verifying the Fix​

After following the steps above, the Typewriter plugin should load without errors. Check your server logs to ensure there are no longer any NoClassDefFoundError errors related to PacketEvents.
