Getting Type not found error implementing source in as3 - actionscript-3

Question

I am trying to just compile and run the demos from this article:
Flash talks to max msp via osc
I am using Flash Develop and Flex SDK with an up to date version of air.
When I run the demo: "as3_MaxFlashHarmony" I get an error I don't know how to fix. The source for the entire project is here:
the project
But specifically the error I am getting says:
col: 30 Error: Type was not found or was not a compile-time constant: OSCMessage.
here is the as3 file that it is specifically referencing:
//IHarmonyApp.as
package
{
import org.tuio.osc.OSCMessage;
public interface IHarmonyApp
{
function updateOSCData(msg:OSCMessage):void;
}
}
It uses the libraries Tuio, MinimalComps, and MonsterDebugger. The thing I don't get is that how can it not find OSCMessage if OSCMessage is properly imported? the IDE is making fine references to it and I can open it's declaration. OSCMessage is a public class. I don't get it.
To give some extra info for potential answers, the IDE flashdevelop can find the library org.tuio.osc.OSCMessage just fine, it gives the error regardless of if org.tuio... is a source path or not, and the overall path does not contain any special characters. I don't know if that might matter, but I feel like this is me making a stupid mistake somewhere. I can provide my project zipped if need be.
Thanks!

I do have the file path org/tuio/osc/OSCMessage.as in my project, and the file OSCMessage exists. FlashDevelop can find it just fine and I can navigate to declaration at that location. This is why I got stumped.
Thanks again

Answer 1

In your AS3 folder apart of your de folder you would need to have org folder with relevant folders and classes.
For example to import org.tuio.osc.OSCMessage you would need a file:
../YourPackageRoot/org/tuio/osc/OSCMessage.as
The other way is including a SWC file (all folders and classes zipped into one swc file).
You can include the swc file in FlashDevelop by right clicking the swc file and selecting Add To Library
