Re: [DrJava] Build process broken?

[Brian S. <bs...@bs...>]

I just tried to update and then compile, and I got the same problem. Then
I remembered: Sometimes, JSR-14 is not smart enough to know when
additional files need to be recompiled. The solution: ant clean compile.

The problem relates to covariant subtyping. JSR-14's implementation of
covariant subtyping on return types requires some of the related classes
to all be compiled at once, and it gets confused (as you saw) otherwise.

In short, if ever a compile fails, try doing a clean first.
