Android Studio 错误：类 android.support.v4.hardware.display.DisplayManagerCompat 已添加到输出。请删除重复的副本

Question

我在尝试使用 Android Studio 构建我的 android 项目时遇到以下异常

Error:Class android.support.v4.hardware.display.DisplayManagerCompat has already been added to output. Please remove duplicate copies.

我在 StackOverflow 上尝试了不同的建议，例如排除下面的包，但它仍然相同：

dependencies {
    dependencies {
        //compile project(':android-beacon-library')
        compile 'org.altbeacon:android-beacon-library:2+@aar'
        compile 'com.squareup.okhttp:okhttp:2.1.0'
        compile ('com.squareup.picasso:picasso:2.2.0') {
            exclude group: 'android.support', module: 'library'
        }
        compile 'com.google.code.gson:gson:2.2.4'
        compile('com.github.Comcast:FreeFlow:v-0.6') {
            exclude group: 'android.support', module: 'library'
        }
    }
}

使用 gradlew.bat 命令我尝试查找重复的条目，但在命令的输出中它不存在，下面粘贴的是 gradlew.bat :app:dependencies 的输出：

您好，将此添加到您的 gradle 文件中。它对我来说很好。希望对您有所帮助！ :)

compile ('com.android.support:palette-v7:21.0.0'){
    exclude module: 'support-v4'
}
