Answer 1

I also face this issue in my maven project using with Eclipse oxygen.1a IDE,

The hierarchy of the type MyClassName is inconsistent

Error showing on class name level,

thereafter I took complete svn update from repository and later Maven -> Update Project and later Project Refresh.

The error was gone...

As per my understanding, this were happening due to unmanaged project version.

Answer 2

In the Eclipse, OSGi environment, the required package can be added to the MANIFEST.MF-> Dependencies tab -> Imported packages. This will solve the issue. Or the plugin which contains the class can be added to the Required Plugin-ins

Answer 6

That means class which implemented by you has reference to the interface or class which again references some other classes or interfaces in other libraries and those are not available.
