Walkthrough

The benchmark module's Gradle build configuration is updated to migrate from the deprecated kotlinOptions { jvmTarget = "11" } syntax to the type-safe Kotlin DSL kotlin { compilerOptions { jvmTarget = JvmTarget.JVM_11 } } pattern, with corresponding import addition.

Changes

Cohort / File(s)	Summary
Gradle Kotlin DSL Migration benchmark/build.gradle.kts	Replaces deprecated kotlinOptions with kotlin { compilerOptions } block; updates jvmTarget to use JvmTarget.JVM_11 enum; adds org.jetbrains.kotlin.gradle.dsl.JvmTarget import.

Possibly related issues

• Using 'jvmTarget: String' is an error. Please migrate to the compilerOptions DSL. #430: Directly addresses the same Gradle migration in benchmark module from deprecated kotlinOptions to modern compilerOptions DSL syntax.

Poem

🐰 A little hop, a Gradle skip,
Deprecated code? We'll flip that script!
From old to new, the syntax gleams,
Type-safe targets fuel our dreams. ✨
