Kotlin DSL vs Groovy DSL for Kotlin Multiplatform Target Configuration

Target Configuration Trade-offs
When configuring platform targets in a Kotlin Multiplatform (KMP) project within IntelliJ IDEA, developers must choose between the Groovy Gradle DSL and the Kotlin DSL (build.gradle.kts). Each approach impacts the development workflow differently regarding type safety and build flexibility.
Constraints and Considerations
The Kotlin DSL provides compile-time validation and superior IDE auto-completion for target definitions, which reduces configuration errors. Conversely, the Groovy DSL allows for more dynamic, conditional logic and generally maintains broader compatibility with legacy third-party Gradle plugins.
There is a known trade-off regarding IDE tooling maturity; while the Kotlin DSL offers better in-editor diagnostics, Groovy scripts often exhibit more stable behavior during large-scale refactoring operations within the IDE.
- Kotlin DSL: Type-safe, inline functions, strong IDE integration.
- Groovy DSL: Dynamic configuration, legacy plugin stability, mature refactoring.
Which DSL is preferable for a KMP project requiring strict type validation for targets versus one requiring highly dynamic build logic? How does the choice affect long-term refactoring stability in IntelliJ IDEA 2025.x or 2026.x?
