我仅以crashlytics为例。
有什么区别
compile('com.crashlytics.sdk.android:crashlytics:2.6.8@aar') { transitive = true; }
和
compile 'com.crashlytics.sdk.android:crashlytics:2.6.8'
最佳答案
如果在Gradle依赖项中使用...@artifacttype表示法，则意味着“仅让我获得此工件，而没有传递性依赖项”。通过额外设置transitive = true，尽管事实如此，您仍在获取传递依赖项。
第一个版本获取带有依赖项的aar，据我记得，第二个版本始终在存在一个jar的情况下获取configurations.compile.each { println it }，否则仅获取依赖项。添加crashlytics以在配置中输出实际文件，您应该会看到区别。
在ojit_code的情况下没有区别:
compile 'com.crashlytics.sdk.android:crashlytics:2.6.8'
