PackageInspectionFailed Error with FlashBuilder, Adobe AIR and iOS development

Question

Building an iOS app using FB4.7 Premium, Air 3.4. At this point, just a very simple test framework. Suddenly, the builder is throwing PackageInspectionFailed errors, and won't complete the build. No explanation why. Simulator runs fine.

I should point out that I have been building and packaging this all day directly to my iPad with no problems. Suddenly, I'm getting this error and the app no longer builds. The last thing I did was add this line: text.autoSize = TextFieldAutoSize.LEFT;

Update

After UNDOing those edits, I'm now getting a new error (is this progress?) ApplicationVerificationFailed. Again with no further info. I haven't changed certificates, build parameters or anything else.

Interestingly, manually dragging the generated .ipa to iTunes and then syncing with the iPad does actually install the app, without error. It just adds a bunch more steps to my testing / debugging process.

What is this error? What are some of the conditions I should be looking for that might cause the error?

Let's get some Adobe eyes on this - there needs to be more information provided about the causes of this error.

Answer 1

I've had this happen intermittently a few times today, seemingly triggered when I updated the AIR SDK to 4.0, and also when I updated some native app.xml configuation data.

After a brief period of swearing, googling and pulling faces at Flash Builder, I found that cleaning the project did the trick.
