Try as I might, I could not figure out for the life of me why my Application Descriptor file couldn’t be generated. I cleaned my application, built, and rebuilt, then even sought out on a completely unsuccessful “Google-ca-pade”. I had the correct AIR runtime version referenced and even had another application file in the project building successfully, however the main mxml file continually gave me this error.
Finally, I stumbled upon, David Deraedt’s AIR Application Descriptor Manager. Honestly, I didn’t think much about it, and hadn’t much in terms of hopes, but after running through the settings for my file and saving it … eureka! Automatic building took over and I have a successful Application Descriptor.
The culprit: a rogue slash “/” mysteriously placed in the original prevented the descriptor from being built.
