Tools to automate calculation of cyclomatic complexity in java?

Question

Are there any tools available for Java that can automagically determine the cyclomatic complexity of given Java code? I have sought out tools online, and have yet to find one.

Answer 1

I use Sonar (my preferred method). There are plugins to "automagically" generate the report at build time (i.e. ANT/Maven, etc...).

One other tool I've used in the past is corbetura. You have to have good unit tests though and finding the quantitative analysis for CC is a little tricky.

Answer 2

One of the metrics produced by Sonar is Cyclomatic Complexity.
I believe it also has an Eclipse plugin (but I haven't managed to find it yet)

Answer 3

AgitarOne from Agitar Technologies (http://www.agitar.com/solutions/products/agitarone.html) calculates cyclomatic complexity in their dashboard report and with their code rules plugin in Eclipse. Note also that McCabe IQ from McCabe Software (http://www.mccabe.com), a sister company of Agitar Technologies, also calculates cyclomatic complexity (aka McCabe complexity) for Java and has an Eclipse plugin for project setup.
