Question

要重用gradle文件中的代码，我通常为某些模块提供一个“基本” gradle文件，然后应用它们并添加可能需要的任何新依赖项。我正在将所有gradle文件转换为新的Kotlin DSL，但使用以下“基本”文件时，出现“未解析参考”错误。

plugins {
    id("com.android.library")
    kotlin("kotlin.android")
    kotlin("kapt")
}

android {
    compileSdkVersion(App.compileSdk)
    defaultConfig {
        minSdkVersion(App.minSdk)
        targetSdkVersion(App.targetSdk)
        versionCode = App.versionCode
        versionName = App.versionName
        testInstrumentationRunner = "android.support.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        getByName("release") {
            isMinifyEnabled = false
            proguardFiles(getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro")
        }
    }

    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }
}

dependencies {
    val implementation by configurations
    val testImplementation by configurations
    val androidTestImplementation by configurations

    implementation(fileTree(mapOf("dir" to "libs", "include" to listOf("*.jar"))))
    implementation(Libs.kotlin_stdlib_jdk8)
    implementation(Libs.appcompat_v7)
    testImplementation(Libs.junit)
    androidTestImplementation(Libs.com_android_support_test_runner)
    androidTestImplementation(Libs.espresso_core)
}

上面的文件在我的根项目中，我只在功能模块中使用以下内容

apply(rootProject.file("base-android.gradle.kts"))

这在Groovy中工作正常，但是在转移到Kotlin时，关于我做错了什么或如何在Kotlin DSL中正确地拥有“基本” gradle文件的任何想法时，它会完全中断？

Answer 1

问题可能来自尝试应用plugins。

plugins {
    id("com.android.library")
    kotlin("kotlin.android")
    kotlin("kapt")
}

apply(rootProject.file("base-android.gradle.kts"))

...

Answer 2

这是我的操作方式：

build.gradle.kts

apply(from = "${rootProject.projectDir}/common-setup.gradle.kts")

common-setup.gradle.kts

apply {
    fun android(configure: com.android.build.gradle.internal.dsl.BaseAppModuleExtension.() -> Unit): Unit =
            (project as org.gradle.api.plugins.ExtensionAware).extensions.configure("android", configure)

    android {
        //common setup here
    }
}

如何在Kotlin DSL中为多模块项目创建“基本” gradle文件？
