网上查询了一下，找到如下的解决方法：
我们常常用 gradle.build文件导入依赖库，但是有时候库依赖会发生版本冲突或多个模块依赖同一个库的情况，这就引出两个问题，如下：
- 版本冲突时， Gradle会下载多个版本的依赖库吗？
- 当多个模块依赖同一个库时，每个模块都会去下载该依赖库吗？
为解决这疑问，接下来我们在 Android Studio用 Gradle举个例子：
gradle.build依赖部分的配置：
|

5

7
8
|
dependencies
{
compile
'com.android.support:appcompat-v7:22.2.1'
compile
(
'com.android.support:design:22.2.1'
)
compile
'com.shamanland:fonticon:0.1.8'
androidTestCompile
'com.android.support:support-annotations:22.2.1'
androidTestCompile
'com.android.support.test:runner:0.3'
androidTestCompile
(
'com.android.support.test.espresso:espresso-core:2.2'
)
}
|
在文件目录下或 Android Studio的 Terminal下敲 gradlew -q app:dependencies 命令，便有以下输出：

可以看出: com.android.support.test:runner:0.3 这个模块原本是依赖于com.android.support:support-annotations22.2.0版本，但由于你又在 gradle.build中加了这行 androidTestCompile 'com.android.support:support-annotations:22.2.1' 故gradle就会下载 com.android.support:support-annotations22.2.1版本，而不会去下载 com.android.support:support-annotations22.2.0版本，因此com.android.support.test:runner:0.3 就会被强转变依赖于com.android.support:support-annotations22.2.1版本
第二个问题，我还是利用上面gradle命令行打出的信息来看看：

仔细看上面的依赖， com.android.support:appcompat-v7:22.2.1 和com.android.support:design:22.2.1，有共同依赖一个 com.android.support:support-v4:22.2.1库，且 com.android.support:design:22.2.1 依赖于com.android.support:appcompat-v7:22.2.1，但从打印出的信息可以看出com.android.support:design:22.2.1 依赖两个库的信息被打了星号标记，这标记意思是忽略这两个依赖的意思，也就是说不去下载这两个库。
从上面的两个例子来看， gradle对于需要多个版本的依赖库来说，一般只会下载你配置导入那个版本，如果没有手动导入，那就会下载所有模块依赖的最新版本那个库，面对多个模块依赖同一个库，每个模块不都会去下载该依赖库，而是下载一个该依赖库，共享给多个模块。

比较上面两种配置 compile信息部分，后面一种配置的com.android.support:design:22.2.1 就没有输出两个打星号的依赖库信息了。
因此遇到这两种情况是，是 gradle能自动帮我们解决掉了这两种情况，对于如何使用 gralde命令行查看库依赖请看官方文档
