Build Error

从 pom.xml 和命令 mvn clean compile exec:java 开始，然后检查 S3Sample.java:86 处的 S3 调用以及报告的两个失败。在已记录的环境中重现构建和执行错误；完成的标准是示例能够编译并运行，且不会出现报告的 Java 兼容性或缺少类失败。

Very new to programming and AWS SDK Java... Just getting started..

After following all the instructions am getting still the Build Failure still.
