 eclipse 报错the hierarchy of the type  is inconsis
The type org.eclipse.core.commands.common.EventManager cannot be resolved. It is indirectly referenced from required .class files

at the same time.

These errors happend because some interface /class in the hierarchy cannot be resolve.
For example: the error is occur in your class - class x, x inherits y, and in turn, y inherits z. However, the compiler cannot resolve z (in above error is EventManager), because z is belong to a library that is not included.
Therefore, you have to add package containing z to the classpath/ or project's Java Build Path (if you are using eclipse).

 

 

如果你写的类A 继承了 B 而B 继承 C,如果接口c或类C不在你所引的jar 包中,就报此信息,导入jar 包即可
