Android Gradle生成失败，错误为定义多个dex文件

在我添加google play服务后，Gradle未能构建

gradle Dependencies我试过将play services可穿戴条目放在一起，并排除第二个条目

dependencies {
    compile 'com.google.android.gms:play-services-wearable:6.5.+'
    compile 'com.android.support:support-v13:21.0.+'
    wearApp project(':wear')
    compile 'com.google.android.gms:play-services-wearable:6.5.87'
    compile files('libs/crashlytics.jar')
    compile files('libs/cup-v1.0.0.jar')
    compile files('libs/support-v4-r12.jar')
    compile files('libs/gson-2.2.4.jar')
}

Gradle控制台输出此错误

我试着把这个添加到我的构建中

dexOptions {
    preDexLibraries = false
}

我在Gradle控制台上也犯了同样的错误。我尝试了以下诊断方法

$ gradle -q dependencies

您正在使用同一库的不同版本

在这种情况下，我想您必须删除这一行：

compile files('libs/support-v4-r12.jar')

这是同一个问题吗：。你能删除一个吗？
