I haven't used Gradle directly, but I've been using Cordova for years, which switched from Ant to Gradle a while back. With Gradle, the incremental builds got way faster. It was clearly burning through up-to-date targets.

But it was still listing the up-to-date targets. Incremental builds in Tup don't even list what's not being done, because there are no "targets" in Tup. That's the whole point of Mike Shal's paper.
