AS3 packages and folder locations

I'm getting this error that says that my package is name doesn't reflect the location of my file. What do I need to do to fix this? I've googled, 开发者_运维百科changed the name of my file, added classpaths. Please provide detailed instructions. I'm having trouble with this.

Code:

package CMA10{

  //Classes and stuff in here

}

Error: (Includes directory information)

/Users/Moshe/Dropbox/Development/AIR/Projects/CMA10/campCD.as, Line 1 5001: The name of package 'CMA10' does not reflect the location of this file. Please change the package definition's name inside this file, or move the file. /Users/Moshe/Dropbox/Development/AIR/Projects/CMA10/campCD.as

If your package looks like:

com.motion.util

The util.as containing the util class file should be located inside: root of your flash file/com/motion/util.as

A classes package needs to be identical to the folder structure that you have the class in and if the top folders location is not the same location as the .fla, a class path needs to be set in the .fla's Actionscript settings to point to the location of that top folder.

Class:

package
{
   public class ClassName
}

Import:

import ClassName;

Document Class: ClassName

This class is in the same directory as the .fla that needs to use it or a class path pointing to the folder containing this class has to be setup in the Actionscript settings of the .fla.

Class:

package com.something.utils
{
   public class ClassName
}

Import:

import com.something.utils.ClassName;

Document Class: com.something.utils.ClassName

This class must be located in "com\something\utils" folder. The "com" folder must be located in the same directory as the .fla that needs to use it or a class path pointing to the folder containing the "com" folder has to be setup in the Actionscript settings of the .fla.
