问题描述
Gradle transitive = true
到底做了什么?Gradle 文档 并不清楚.这是在 build.gradle
中的 compile
上下文中.就我而言,我依赖 Android 的 crashlytics.
What does Gradle transitive = true
do exactly? It is not clear from the Gradle documentation. This is in the context of compile
within build.gradle
. In my case I'm depending Android's crashlytics.
compile('com.crashlytics.sdk.android:crashlytics:2.2.2@aar') {
transitive = true;
}
几个 Gradle 文档(这里 和 here) 暗示传递"默认为真.然而,删除 transitive = true
会导致没有引入传递依赖(特别是 KitGroup
).
Several Gradle docs (here and here) imply that "transitive" defaults to true. Yet removing transitive = true
results in transitive dependencies not being brought in (in particular KitGroup
).
class file for io.fabric.sdk.android.KitGroup not found
文档说它默认为 true,但实际行为似乎相反.
The docs say it defaults to true, yet the actual behavior seems to be the opposite.
我正在运行 Gradle 2.2.1.也许行为在 2.2 和 2.4 之间发生了变化?
I am running Gradle 2.2.1. Perhaps the behavior changed between 2.2 and 2.4?
推荐答案
您正在使用 @aar
表示法.
这意味着您只想下载 aar
工件,而不要下载传递依赖项.
You are using the @aar
notation.
It means that you want to download only the aar
artifact, and no transitive dependencies.
你可以在 Gradle 中查看依赖管理在官方文档中.特别是:
You can check Dependency management in Gradlein the official documentation. In particular:
仅工件表示法创建模块依赖项,该依赖项仅下载具有指定扩展名的工件文件.忽略现有模块描述符.
如果您想下载依赖项,使用 @aar
表示法,您应该添加 transitive=true
.
Using the @aar
notation if you want to download the dependencies, you should add transitive=true
.
我希望省略@aar 它应该可以在不添加传递属性的情况下工作.
I'd expect that omitting @aar it should work without adding the transitive attribute.
