Question

I am trying to Make project in IDEA and i have compilation error. How to solve this?
I dont have duplicated classes in project. When I am pressing Jump to source it shows me the class from directory target of project.

duplicate class: com.kmware.ttk.kladr.model.KladrSchemStreet_

and the same with all classes in project

IDEA 11.1.3
UBUNTU 12.04
JBoss as 7

additional code:

Have you somehow added the compile output of your module as a dependency? Either directly through IntelliJ or via Maven.
