Meet the Sonargraph Gradle Plugin – and Say Goodbye to JDepend

With the release of Sonargraph 8.8.0 today we also released the first version of our brand new Gradle plugin. It allows you to create reports for any Java project, even those that do not have a Sonargraph system specification. This is a quick and easy way to get some metrics and other findings like circular dependencies about your project. In this article I am going to show you, how you can use our Gradle plugin to make your build fail if your system contains cyclic package dependencies. Believe it or not, there are still people out there that use JDepend for this very reason (I did too, but that was more than a decade ago). Since you can do everything I am describing now with our free Sonargraph-Explorer license including the interactive visualization of cycles, I think you won’t regret saying “Good Bye” to JDepend and “Hello” to Sonargraph.

Assess and Control Component Coupling in Software Systems

Over time software systems tend to develop several negative symptoms: simple changes require a surprisingly big effort to be implemented, changes cause the system to break in unrelated areas, reuse of code in other systems is simply not  feasible, the code is hard to read and understand even for the directly involved programmers. One of the main reasons of facing these symptoms is an unintended increase of the overall system coupling.

Except for very small systems the manual control of the overall coupling is a tedious task – a tool-based approach is needed. Sonargraph-Explorer is such a tool and among other things it helps the developer to assess and control coupling and work against its accidental increase. It is the first product built upon the new Sonargraph Next Generation platform supporting Java, C# and C/C++. It offers different visualizations of dependency structures and a powerful scripting engine based on Groovy which allows extending the built-in analysis capabilities.

The following content introduces the needed definitions and terms related to component coupling (one way to express the overall system coupling). It explains how to use Sonargraph Explorer to visualize the corresponding dependencies and determine components contributing significantly to the overall system coupling with a custom script automatically.
