我有 pom.xml 文件，现在我添加了一些依赖项。我的pom文件看起来像这样......

现在它给我带来了这样的错误......

引起：java.lang.ClassNotFoundException：com.amazonaws.protocol.json.SdkJsonMarshallerFactory

实际问题是混合不同版本的 AWS Jars。

例如，您应该使用1.10.39或1.10.3用于以下依赖项。

同样，对于所有其他com.amazonawsgroupId。

<dependency>
       <groupId>com.amazonaws</groupId>
       <artifactId>aws-java-sdk</artifactId>
       <version>1.10.39</version>
     </dependency> 
    <dependency>
        <groupId>com.amazonaws</groupId>
        <artifactId>aws-java-sdk-core</artifactId>
        <version>1.10.3</version>
    </dependency>

我遇到了同样的问题。com.amazonaws为所有groupId保持一致的版本解决了这个问题。

由于我看不到您在哪里定义构建变量，我无法确定，但您的 AWS 库之间可能存在版本不匹配。该类似乎较新，并且可能不存在于您要下载的任何版本的库中。（我在 1.11.72 中看到了参考，但在此之前它可能已经存在）。

我会做一个“mvn 依赖：树”，看看各种 AWS 库的所有版本都被拉下并整理出来。

*注意：我遇到了同样的问题，但在我的情况下，我使用的是 MVN 阴影插件，并且上游某处它正在过滤掉这些类..
