Another release of GradleTest today - 5.1.0. The initial feature was to support Gradle 9.8 and JDK27, but along the way it also added a feature to use a custom manifest per Gradle version under test if anyone needs it. Because yes, you might develop using one version of the JDK and a specific Gradle API, but you might want to test against a different JDK & Gradle version family. And sometimes that affects variants, especially if transitive dependencies have variants. Now you can control that behaviour very simply. (rolling that kind of thing manually with Testkit can be PITA). See gradletest.ysb33r.org
