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

当我尝试使用android Studio构建我的android项目时，我面临以下异常

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

我在这里尝试了StackOverflow的不同建议，例如排除如下所示的包，但仍然是一样的：

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

使用--info或--debug选项运行Gradle以找出原因。当您在两个不同的目录中有相同的文件名时（即，在主源代码中，以及在测试源代码/测试IT源代码中的某个地方等），通常会发生这种情况。我还发现，如果您生成了项目中没有.java文件的.class文件，但您在运行中创建了它们（例如：在JIBX/XSL等操作期间创建的），则可以使用--info或--debug选项运行Gradle来找出原因，那么这种情况就会发生。当您在两个不同的目录中有相同的文件名时（即，在主源代码中，以及在测试源代码/测试IT源代码中的某个地方等），通常会发生这种情况。我还发现，如果生成的.class文件在项目中没有.java文件，但您在运行中创建了它们（例如：在JIBX/XSL等操作期间创建），则可以在依赖项之前添加以下代码：配置{all*.exclude group:'com.android.support.v4'，模块：'support-v4'在依赖项之前添加以下代码：configurations{all*.exclude group:'com.android.support.v4'，module:'support-v4'}，并告诉我它是否有效。

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