How to run es after I build with maven

I download the es source code from github and I build success it with maven: mvn clean package -DskipTes.
could someone teach me how to debug then. I run but I got this:
Unable to locate the class org.elasticsearch.bootstrap.ElasticsearchF : java.lang.ClassNotFoundException

pls give some suggestion where I'm wrong, or tell me the steps of how to build source code and debug with source code.


Could someone help!!!
