If you are managing a big java project and you use maven changes are high that you are running test coverage and code quality reports.
Analyzing this multitude of reports can be quite exhausting. At work we use Sonar, which uses data from a lot of maven reports (code coverage, pmd, …) and creates an overview on your project. AND it can be setup in about 20 minutes.
SONAR is a code quality management platform, dedicated to continuously analyze and measure technical quality, from the projects portfolio to the class method.
You can read here about the features of it. It even has a time machine to let you investigate the changes of your project over time.
