It does. You have a user error somewhere.

I used to generateAsync as part of the build process, but I don't find
it useful anymore. It usually just causes problems for Eclipse because
we hadn't (at last time I checked) taught M2E how to handle these
automatically. Missing generated-sources directories, forcing you to
do Project>Clean on other modules, it's really a pain.
Nothing stops you from modifying your project once it is set up, but I
think the default simple mode of having the Async.java in the source
tree is the best for new people.
