The hierarchy of the type CLASSNAME is inconsistent when extending DefaultFtpSessionFactory

Question

I'm brand new to Spring, and I'm facing a real problem, and I didn't know how to solve

when I extend DefaultFtpSessionFactory , the compiler gets annoyed telling me that The hierarchy of the type CLASSNAME is inconsistent .

I searched a lot and found that this could happen when there are classes that are needed, which are not in the Build path.

Does anybody know the how-to deal with such compilation issue ?

Thanks in advance.

我想知道您是否使用了一些有用的“依赖关系管理”工具，例如Maven或Gradle，并将spring-integration-ftp作为项目的依赖项，并允许该工具选择所需的可传递依赖项。
