SVNKit or analyzing SVN content in Java

The other day I was looking for a piece of software that could help me pull data out of SVN repository so I can do a little analysis on it. Browsing over the net, I run into several tools, but the one that finally caught my eye was SNVKit. The package does a lot of stuff, but for instance, if you are only interested on pulling information out, it makes your like quite easy. The code below is just a simple example of how you can use it to pull information out of a SVN repository.

import java.util.LinkedList;
 
import org.tmatesoft.svn.core.ISVNDirEntryHandler;
import org.tmatesoft.svn.core.SVNDirEntry;
import org.tmatesoft.svn.core.SVNException;
import org.tmatesoft.svn.core.SVNURL;
import org.tmatesoft.svn.core.internal.io.svn.SVNRepositoryFactoryImpl;
import org.tmatesoft.svn.core.internal.wc.admin.SVNEntry;
import org.tmatesoft.svn.core.wc.SVNClientManager;
import org.tmatesoft.svn.core.wc.SVNLogClient;
import org.tmatesoft.svn.core.wc.SVNRevision;
import org.tmatesoft.svn.core.SVNNodeKind;
 
public class SVNReader {
 
    public static void main ( String [] sArgs ) throws SVNException {
          final LinkedList<SVNDirEntry> lstFiles = new LinkedList<SVNDirEntry>();
 
          SVNRepositoryFactoryImpl.setup();
 
          SVNClientManager clientManager = SVNClientManager.newInstance();
 
          SVNLogClient lc = clientManager.getLogClient();
          SVNURL svnUrl = SVNURL.parseURIDecoded(
                    "svn://some.server.com:3690/path/to/trunk"
                    );
          lc.doList(svnUrl, SVNRevision.HEAD,  SVNRevision.HEAD, false, true, new ISVNDirEntryHandler() {
                    public void handleDirEntry(SVNDirEntry svnEntry) throws SVNException {
                              if ( svnEntry.getKind()==SVNNodeKind.FILE) {
                                        lstFiles.add(svnEntry);
                              }
                    }
          });
 
          for ( SVNDirEntry svnEntry:lstFiles ) {
                    System.out.println(svnEntry);
          }
      }
}
