How can I get clean Gradle output on Travis CI?

Example output for a normal build on Travis CI using Gradle: https://travis-ci.org/2m/gradle-travis-test/builds/8579228 Gradle seems to think that the console has the same capabilities as a normal ANSI console, while in reality it only supports some of those features. Specifically, it seems to support colors, but not updating/replacing text (it's append-only). How can I tell Gradle to use "plain"
