Question

我仅以crashlytics为例。

与

有什么不同

    compile('com.crashlytics.sdk.android:crashlytics:2.6.8@aar') { transitive = true; }

和

    compile 'com.crashlytics.sdk.android:crashlytics:2.6.8'

Answer 1

如果在Gradle依赖项中使用...@artifacttype表示法，则表示“只获取此工件并且没有传递依赖项”。通过另外设置transitive = true，您将获取传递依赖性，尽管如此。

第一个版本获得带有依赖关系的aar，据我所知，第二个版本总是得到jar如果存在，除了依赖关系。添加configurations.compile.each { println it }以输出配置中的实际文件，您应该看到差异。

在crashlytics的情况下，没有区别：

@aar与transitive = true的含义是什么？
