Why You Should Consider Migrating Your Gradle Scripts to Kotlin DSL

Gradle Kotlin DSL (Domain Specific Language) is a Kotlin-based language used to configure Gradle builds. It provides a more concise and type-safe way to define build scripts compared to the traditional Groovy-based Gradle scripts.

Gradle Kotlin DSL was introduced to solve some of the challenges associated with Gradle Groovy-based scripts, such as the lack of static typing and code completion, as well as the difficulty of maintaining complex build scripts.
