java.lang.NoClassDefFoundError : com. amazonaws.services.s3.AmazonS3Client

Question

我已经在我的 eclipse (ADT eclipse) 中导入了 S3Uploader 示例，并且我正在尝试运行它。

我已经导入了项目，然后添加了以下 jar 项目 > 属性 > java 构建路径 > 添加 jar

2014年2月2日下午1:24 6,376,630 aws-android-sdk-1.7.1.1-debug.jar 02/02/2014 01:14 PM 281,550 aws-android-sdk-1.7.1.1-s3.jar 02/02/2014 01:24 PM 5,587,005 aws-android-sdk-1.7.1.1.jar

项目编译并构建得很好。但是当我运行它时，它给出了以下异常

我还看过AWS SDK NoClassDefFoundError: com.amazonaws.services.s3.AmazonS3Client

它也说明了我已经做过的事情。

如何修复它？
