All the extensions have also been updated: ANTLR4 extension Archive extension Checkstyle extension Command Line Execution extension Generated Version extension JaCoCo Report extension PIT Mutation Testing extension PMD extension Property File extension Spring Boot extension TestNG extension Tests Badge extension The Kotlin extension has been completely reworked. It now compiles using a local installation of the Kotlin compiler, making it possible to test with multiple versions of Kotlin. Dokka now has its own extension. There's also a Kotlin project template on GitHub with support for the Dokka and Detekt extensions.
