我的IntelliJ DropWizard项目中没有安装外部依赖项？

Question

我试图将这2个Maven依赖项导入到我的项目中：

https://mvnrepository.com/artifact/com.amazonaws/aws-java-sdk/1.11.578 https://mvnrepository.com/artifact/com.amazonaws/aws-java-sdk-dynamodb/1.11.578

我将它们添加到了pom.xml文件中：

我在IntelliJ中打开了项目，右键单击pom.xml文件上的Download Sources，单击Re-Import，仍然在导入语句上看到一条错误消息“无法解析符号'aws'”（检查“ OfferingMemo.java”对于发生错误的位置）。这是项目：https://github.com/SixteenDollars/help
