Description

Contains a plugin for Gradle tests to set Kotlin arguments (api and language version) via ‘gradle.properties’ or via -P command line flag.

Available properties

• kotlin.test.languageVersion - sets -language-version to the given value
• kotlin.test.apiVersion - sets ‘-api-version’ to the given value
• kotlin.test.overrideUserValue - make the best effort to override values set explicitly by the user in the build script

Plugin usage in the external projects

Plugin is also possible to use not only in the tests, but on the external projects. To do this follow these steps:

• Run ./gradlew :gradle:kotlin-compiler-args-properties:install (short variant ./gradlew :gr:k-c-a-p:i)
• In the external project modify settings.gradle.kts following way:

pluginManagement {
    repositories {
        mavenLocal()
        // other repos defined by the project
    }
    
    plugins {
        id("org.jetbrains.kotlin.test.kotlin-compiler-args-properties") version "1.9.255-SNAPSHOT"
        // other plugin declarations by the project
    }
}

• In the external project modify root build.gradle.kts following way:

plugins {
    id("org.jetbrains.kotlin.test.kotlin-compiler-args-properties")
    // Other plugin declarations by the project
}

allprojects {
    apply(plugin = "org.jetbrains.kotlin.test.kotlin-compiler-args-properties")
    repositories {
        mavenLocal()
    }
}

This plugin should be also added similar way into any included build.

NOTE: Build logic (for example buildSrc) and projects building Gradle plugins written in Kotlin should not apply this plugin, as Gradle Kotlin runtime most probably will not be compatible with values under-the-test (for example language version ‘2.0’).
