为什么具有运行时作用域的库被添加到debugCompileClasspath？

问题描述 投票：7回答：1

如果我将我的库添加到项目中，并运行命令：

> gradlew -q app:dependencies --configuration debugCompileClasspath > app_dependencies_compile.txt

为什么com.github.kolyall:utils:1.0.4 lib在com.android.support:appcompat-v7中使用runtime范围获得CompileClasspath lib（和其他）？如果它们的范围应该是runtime，为什么它们被添加到CompileClasspath？

输出是：

在Gradle 5.0 gradle不支持IMPROVED_POM_SUPPORT之前，所以它将所有传递依赖关系视为compileby默认值。 （非罐装包装不受支持。）

Related Gradle Bug

这是在Gradle 5.0修复的，其中IMPROVED_POM_SUPPORT是默认行为。

虽然它不是强制性的，但告诉gradle提供依赖是Android存档使用是一个很好的做法

implementation 'com.github.kolyall:utils:1.0.4@aar'{
    transitive=true
}

同时在gradle中声明依赖。注意库版本后的@aar

现在将gradle升级到5.0或更高版本后，

compileClasspath输出是

+--- com.google.code.gson:gson:2.8.5
+--- org.apache.commons:commons-lang3:3.8.1
+--- io.reactivex:rxjava:1.1.0
\--- com.github.kolyall:utils:1.0.4
     \--- net.danlew:android.joda:2.8.2
