title: unable to achieve lucene solr code debugging
body: <p>I'm a stranger in the world of lucene-solr. I know a little about it and want to learn more of it and want to contribute in it.</p>
  
  <p>Till now I've learnt to configure the solr server on any machine. But I want to learn the internal functioning of solr which I think can be done by debugging the source code of the project. I've already imported it into eclipse successfully, but is unable to debug the code.</p>
  
  <p>I'm excepting a help from the community to guide me with simple steps to start with debugging of the code. I took help from internet from various blogs for this but failed to achieve the same.</p>
  
  <p>I'm using solr-6.2.1.</p>
