android导入第三方包后出错 求大神解惑

出现如下错误

Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.

com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/NOTICE.txt
File1: C:\Documents and Settings\Administrator\AndroidStudioProjects\MyApplication\app\libs\commons-codec-1.6.jar
File2: C:\Documents and Settings\Administrator\AndroidStudioProjects\MyApplication\app\libs\commons-logging-1.1.3.jar

Duplicate files copied in APK META-INF/NOTICE.txt 初看像文件重复，clean一下试试，找一下这个文件。

 packagingOptions {
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
    }
