Re: [ajdt-dev] EnsureAJBuilder.ensureNoJavaBuilder(..) and APT

[Andrew Eisenberg <andrew@xxxxxxxxxxxx>]

Thanks for the patch.  I'll take a look at it next week.

So, my understanding is that you require the javaBuilder only to run
APT, and so there is no need to generate the class files, other than
what APT generates.  And since APT will run before the ajBuilder,
there should be no conflict between the two.  This sounds quite
reasonable to me, as long as you can deal with APT's limitations.
