Solved Could not pass event PlayerQuitEvent to...

Because the CustomNPCs mod isn't an opensource project I've tried to make a plugin which transfers playerdata(active quests, companions, faction points, etc) from localhost(first server) to second server making it smth like multi-server. When player moves to another server he will se all his quests from another server. Same plugin with another settings placed on second server.

For transfer operations via SFTP I used JSch library: API
Example was taken from here: SOverflow

Craftbukkit core: 1.7.10-R0.1

My coding experience is ~1month, so... The error is explained in thread title :\
At least I tried... xD

This error is stating that it could not find the class "com.jcraft.jsch.JSchException". Make sure you have the correct imports and that the server running this code has access to that API.

 

Ahh.. Srry, I forgot that I added JSch as external lib

Not fixed. :c

I've tried to configure Java Build Path adding jcsh.jar from /lib/jsch.jar
http://prntscr.com/lsc641

The .classpath has <classpathentry kind="lib" path="lib/jsch-0.1.55.jar"/> but it's still not working.
Server are still pointing that it couldn't find "com.jcraft.jsch.JSchException"

@ShadX

Could you post the .jar file of your plug-in? I can open it up and see whether or not the missing class is actually there.

 

Fixed it 5 mins ago. Thank y'all guys!
I just moved JSch lib to server root/plugins/libs/Jsch-0.1.55.jar

And changed manifest Class-path to:
Class-Path: libs/jsch-0.1.55.jar
