I was playing around with annotation processing and was unable to use generated files directly via an import in my code. Instead I had to prepend the generated class with its complete package. I posted a SO question error: package generated.schema does not exist.
In the end I figured out the reason for this, turned out to be pretty simple, see my answer to the same post. Turned out the error was because I was generating the files at last round of processing, instead of anywhere in between.
So my questions are:
How does generating files at last round vs generating files at in between rounds changes accessing the generated files in code?
Is there a specific reason (Java-related or otherwise) for this behavior?
