I neeed a free tool to count SLOC on a Java project. I only really need the following metrics:
- SLOC
- number of comment lines
- optionally javadoc metrics
- optionally sort statistics by file type (.java, .js, .css, .html, .xml, etc)
Bonus:
- 100% Java, I don't like mix something like sloccount with cygwin
- netbeans plugin
- or preferably, maven plugin

Did you consider using Sonar (which uses its own internal tool since version 1.9, sonar-squid, instead of JavaNCSS which has some flaws and doesn't work well with Java 1.5 or 1.6 projects)? This is the kind of report you'll get:

Sonar does a lot more than just collecting SLOC though, maybe not what you want.
