Installing eclipse plug-in built by Tycho - eclipse

Question

I want to install eclipse plug-in that was build with help of Tycho.
When I call mvn clean install Maven exits with SUCCESS, and in target directory there is .jar file.
I can't make Eclipse to work with this .jar, it says that file could not be found.
Am I missing something here? How to use my tycho built plug-in?
Here is my pom.xml:
