JavaNCSS - Source Measurement Suite for Java

Build Status Coverage Status License Maven Central

Ever wondered how many lines of code or how many classes there are in the JDK? Curious about the size of your own projects - or do you want to keep track of your work-progress. That's what JavaNCSS is for.

JavaNCSS is a simple command line utility which measures two standard source code metrics for the Java programming language. The metrics are collected globally, for each class and/or for each function.

Features

  • Metrics can be applied to global-, class-, or function-level.
  • Non Commenting Source Statements (NCSS).
  • Cyclomatic Complexity Number (McCabe metric).
  • Packages, classes, functions and inner classes are counted.
  • Number of formal Javadoc comments per class and method.
  • Average values are calculated.
  • Command line driven.
  • A GUI is provided for better output browsing as well as the integration of JavaNCSS in a project manager and class browser named Jacob (http://www.kclee.de/clemens/jacob/) for easy selection of input source files.
  • XML output (optional).
  • XSLT stylesheets provided for further generation of HTML, and SVG reports and as a basis for your own custom reports.
  • Ant task (written by Steve Jernigan).
  • Support for Java 5 syntax (generics, enums, etc.).
  • Support for Java 7 syntax (try with resource, literals, etc.).
  • 100% Pure Java.
  • Free software (GNU LGPL).
