Solved Bukkit Plugin: Programming Error

Hi! I have a little problem if I start my test plugin: Caused by: org.yaml.snakeyaml.scanner.ScannerException: null; mapping values are not allowed here
What does it mean? What can I do that this error doesn't appears?

Please help me!

 

Hi, could you please upload your plugin.yml?

MfG Xenira

 

Hi here is my plugin.yml:

Code:

name: MultiPlugin
version: 1.0
author: Eric
main: com.eric.multiplugin.mp
commands:
  usage: /notch
    description: Who is Notch?

 

Try this:

Code:

name: MultiPlugin
version: 1.0
author: Eric
main: com.eric.multiplugin.mp
commands:
notch:
    description: Who is Notch?

 

theCodeBro i think, you need to put two spaces infront of "notch" because its under commands in the hirachie

Code:

name: MultiPlugin
version: 1.0
author: Eric
main: com.eric.multiplugin.mp
commands:
  notch:
    usage: /notch
    description: Who is Notch?

 

No that didn't work. But a new error comes up if I start it now:

Code:java

name: MultiPlugin
version: 1.0
author: Eric
main: com.eric.multiplugin.<YOUR MAIN CLASS NAME>
commands:
  notch:
    usage: /notch
    description: Who is Notch?

 

My main class is mp.java and I wrote com.eric.multiplugin.mp but the same error occurred.

 

Can you send me your .jar?

 

Yes I hope you can download this: http://www.file-upload.net/download-8832436/MP.jar.html

 

You didn't save your package and your class

 

I thought I saved it... Can you describe me another time how I can save this

 

sohardhun15 Thanks...
