Number one reason for not using a cached build. "Reliability". > - Case 1: A problem is solved just by doing a clean build. > A non-starter, unless you're building Hello World.

A false failure like Case 1 where the build fails but can be fixed with a > clean build is annoying but not a critical problem It is a critical problem, economically. That's the whole point of build tools that optimize building. as long as there is a way to force a clean build. The big problem is Case 2 > where it passes because of picking up something from the cached build. That just means your build tooling is flawed.

Without it they would have no way of knowing what to build and what not to build. G -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
