Tracking Maintainability index (MI) in Java

I need a good开发者_如何学Go fast, reliable (open source would be a plus) tool for Java for tracking Maintainability index and simliar code metrics to show the customer the progress of working on refactoring issues.

What would be your suggestion to apply?

Sonar is a pretty great tool for tracking all sorts of metrics against a number of projects and maintaining a history over time.

SONAR is an open source quality management platform, dedicated to continuously analyze and measure source code quality, from the portfolio to the method.

A very interesting and usable tool for this is Lattix. It checks all class references to create a dependency matrix which is quite a good metric for maintainability; if there are a lot of dependencies in your codebase, then a change in one place will more likely cause a cascade of changes in other classes. I'm not saying it is the only way to measure maintainability, but I think it might be one of the best approaches.

Cool extra feature is refactoring support, which allows you to plan refactoring (to reduce unwanted dependencies) and gives you a list of TODO tasks to complete it. And it is visually quite intuitive, so you can easily track the 'health' of your project at a glance.
