Android 无法排除未使用的依赖项

我试图从play services映射中排除支持注释，但似乎不起作用。与此相关的依赖关系树粘贴在下面。请让我知道如何添加排除项

这就是我试图排除的方式

compile ('com.google.android.gms:play-services-maps:9.6.1',
{
    exclude group: 'com.android.support', module: 'support-annotations'
})

这就是那棵树

_releaseApk - ## Internal use, do not manually configure ##
+--- com.google.android.gms:play-services-maps:9.6.1
|    +--- com.google.android.gms:play-services-base:9.6.1
|    |    +--- com.google.android.gms:play-services-basement:9.6.1
|    |    |    \--- com.android.support:support-v4:24.0.0 -> 25.1.0
|    |    |         +--- com.android.support:support-compat:25.1.0
|    |    |         |    \--- com.android.support:support-annotations:25.1.0
|    |    |         +--- com.android.support:support-media-compat:25.1.0
|    |    |         |    +--- com.android.support:support-annotations:25.1.0
|    |    |         |    \--- com.android.support:support-compat:25.1.0 (*)
|    |    |         +--- com.android.support:support-core-utils:25.1.0
|    |    |         |    +--- com.android.support:support-annotations:25.1.0
|    |    |         |    \--- com.android.support:support-compat:25.1.0 (*)

我想你的语法有错误。 应该是这样的:

compile ('com.google.android.gms:play-services-maps:9.6.1')
{
    exclude group: 'com.android.support', module: 'support-annotations'
}

你能把整个格雷德尔档案都贴出来吗？

compile ('com.google.android.gms:play-services-maps:9.6.1')
{
    exclude group: 'com.android.support', module: 'support-annotations'
}
