Java Maven中两个依赖项的不兼容性

在我的程序中，我尝试连接到两台服务器。在不同的项目中，这两种连接都能完美地工作。然而，当它们在同一个maven projet中时，我在连接过程中遇到了一个异常

在我的例子中，当我在pom中添加这个依赖项时

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk</artifactId>
    <version>1.9.35</version>
</dependency>

然而，当我删除这个依赖项时，我对连接到CloudFoudary没有任何问题。但是，我使用的aws类有一个错误

---

我的问题是。如何添加这两个依赖项而不出现此异常

我希望这个讨论会对您有所帮助（Spring和CloudFoundry之间的Jackson版本兼容性）：@Berger非常感谢。它有效；）我希望这个讨论会对您有所帮助（Spring和CloudFoundry之间的Jackson版本兼容性）：@Berger非常感谢。它有效；）
