I'm Creating a Plugin, Kinda Need help

I'm creating a plugin and when I run it this shows up
"Class Ten\IronCannon not found" (EXCEPTION) in "/src/spl/BaseClassLoader" at line 144
Please help, I'm pretty new to this stuff

Submit a zip of the plugin source to http://pmt.mcpe.me and read the message.

You either haven't declared the class or namespace on the file properly or haven't given the correct directory when your calling that file.

Could I PM you my Code, could u check it

Check it with http://pmt.mcpe.me :/

The website when I click on the Create button it says website in mantaince

Oops, forgot to turn it back on. Try again now.
