It’s a code quality management platform that allows developer teams to manage, track and eventually improve the quality of the source code. It’s a web based application that keeps historical data of a variety of metrics and gives trends of leading and lagging indicators for all seven deadly sins of developers.
Sonar is an open source platform used by development teams to manage source code quality. Sonar has been developed with a main objective in mind: make code quality management accessible to everyone with minimal effort.
As such, Sonar provides code analyzers, reporting tools, defects hunting modules and TimeMachine as core functionality. But it also embarks a plugin mechanism enabling the community to extend the functionality (more than 35 plugins available), making Sonar the one-stop-shop for source code quality by addressing not only developers but also managers needs.
Know About SonarJava! Is it replacement for Checkstyle, PMD, FindBugs?
SonarJava has a great coverage of well-established quality standards. The SonarJava capability is available in Eclipse and IntelliJ for developers (SonarLint) as well as throughout the development chain for automated code review with on-premise SonarQube or on-line SonarCloud.
SonarJava is a code analyzer for Java projects. Information about the SonarJava features is available below;
SonarQube is currently on the way to deprecate PMD, Checkstyle and Findbugs and use their own technology to analyze Java code (called SonarJava). They do it, because they don’t want to spend their time fixing, upgrading (or waiting on it) those libraries (e.g. for Java 8), which for example uses outdated libraries. Well at least since SonarQube 6.3+ it seems to be that Findbugs is (at the moment) no longer supported as a plugin.
