Subject [jira] Commented: (DERBY-3117) Adjust master build script to require the Java 5 compiler to build Derby
Date Thu, 18 Oct 2007 15:56:50 GMT

Rick Hillegas commented on DERBY-3117:
--------------------------------------

I agree that we could add that check to the compiler verification target which is invoked
during build initialization. It would reduce the brittleness, but probably not eliminate it.
We could imagine adding similar checks to make sure that the jdk14 and jsr169 classpaths are
sensible too. However, I don't have confidence that this approach will prove the correctness
of the code at compile-time. Getting people to declare these variables up front , as you suggest,
probably mops up most of the problems. The remaining problems can be flushed out after checkin
when the build breaks on someone else's machine--I think that risk is acceptably small. Thanks.
