Gradle 5.0 RC1 Release

The Gradle Build Tool Team released the first 5.0 release candidate this week, Gradle 5.0 RC1. RC1 includes all of the features planned for 5.0 including all of the features planned for the Kotlin DSL 1.0 release, task timeouts, dependency version alignment, Java 11 support, improved gradle init, and more. It also includes some potentially breaking changes and removes some deprecated features as described in the upgrade guide.

Take a look at the RC1 Release Notes and the Upgrading from Gradle 4.X Guide to see how version 5.0 may affect your build. If you want to try the new Kotlin DSL, see the Groovy to Kotlin DSL Migration Guide. If you find bugs while upgrading to 5.0 RC1, please let us know by filing a issue on GitHub.

For Gradle Enterprise users, the newly released Gradle Enterprise 2018.4.2 is compatible with Gradle 5.0 and uses Build Scan Plugin 2.0.1 which has also been released with support for Gradle 5.0.

KotlinConf 2018 Recap

Gradle ❤️ Kotlin so it makes sense that several Gradle engineers were in attendance at KotlinConf to promote the upcoming release of Kotlin DSL 1.0 and talk with the Kotlin community.

Paul Merlin gave a talk on Type-Safe Build Logic with Gradle Kotlin DSL. This talk shows how to switch from the Groovy DSL to the Kotlin DSL and some of the benefits of using the Kotlin DSL with IntelliJ and Android Studio like debuggable build scripts, source-lookup, and context-aware refactoring. This talk also covers the performance implications of using the Gradle Kotlin DSL. It’s a must-watch for everyone getting ready for the 1.0 release of the Kotlin DSL in Gradle 5.0.
