[mono-android] Problem with a wrapper for Amazon in-app purchases

[Rodrigo 'r2d2rigo' Diaz]

Hello,

I'm trying to create a wrapper to call Amazon's IAP API from a Mono for
Android game. Using the Binding Library and adding the JAR outputs the
following error:

ExportJarToXml:
    SourceJars:
      Jars\in-app-purchasing-1.0.3.jar
    ReferenceJars:

I can't find the class AbstractCommandTask anywhere in the JAR provided.
Has anyone tried something similar?

Cheers.
