在Terminal中，可以通过 gradle 的命令查看项目中所使用库的版本，并且可以更加直观看到库之间的依赖关系。同时它们可以帮助您跟踪并解决与库版本冲突有关的任何问题。Building Android apps

dependencies

指令：

$ ./gradlew :app:dependencies –configuration compile

说明：

在Window系统下，无需使用./开头，直接使用gradlew即可。

执行app模块下的dependencies任务；额外配置compile,编译环境下的依赖项。

结果：

:app:dependencies

从中可以发现44行：com.alibaba:arouter-api:1.2.1.1依赖的support-v4库版本比当前环境版本低，因此可以使用exclude剔除旧版本库，避免重复，也可以瘦身apk，何乐而不为呢？

compile('com.alibaba:arouter-api:1.2.1.1') {

exclude module: 'support-v4'

}复制代码
