提问by JJ180
I am seeing the following error when attempting to launch my standalone application:

I have checked my classpath and there is only one instance of the class HttpComponentsClientHttpRequestFactory, residing in the spring-web-3.2.1.jar file.
我检查了我的类路径，并且只有一个 HttpComponentsClientHttpRequestFactory 类的实例驻留在 spring-web-3.2.1.jar 文件中。
When I look at the source for this class, there is no mention of it extending any final class or methods.
当我查看这个类的源代码时，没有提到它扩展了任何 final 类或方法。
I am a little confused as to what is happening.
我对正在发生的事情感到有些困惑。
Can anyone offer some pointers please?
任何人都可以提供一些指示吗？

Make sure that the classpath you are using for building is the same as that which you are using for testing. The most common cause of VerifyErrors is inconsistencies between the classes you built against, and the classes that you are testing against. That is, at its core, driven by a version issue.
确保用于构建的类路径与用于测试的类路径相同。VerifyErrors的最常见原因是您构建的类与您测试的类之间的不一致。也就是说，其核心是由版本问题驱动的。
