导致：java.lang.ClassNotFoundException：com.amazonaws.transform.JsonErrorUnmarshallerV2

Question

我很确定这是因为不匹配的版本，所以即时通讯共享我所有的POM文件，我有一个项目的模块，当我在一个

<dependency> 
      <groupId>com.amazonaws</groupId> 
      <artifactId>aws-java-sdk-bom</artifactId> 
      <version>1.11.109</version> 
      <type>pom</type> 
      <scope>import</scope> 
     </dependency> 

      <dependency> 
      <groupId>com.amazonaws</groupId> 
      <artifactId>aws-java-sdk-dynamodb</artifactId> 
      <version>1.11.109</version> 
    </dependency> 



<dependency> 
    <groupId>com.amazonaws</groupId> 
    <artifactId>aws-java-sdk-cognitoidp</artifactId> 
    <version>1.11.109</version> 
</dependency> 

：在这里我不得不使用cognito我加入的依赖，改变了所有其他以较新的版本cognito不支持旧版本，但现在在另一个模块IM收到此错误

添加aws-java-sdk依赖性将起作用。
