SonarQube Frequently asked questions (FAQ) | SonarQube FAQs

Answers – YES and NO

Why Yes?

Sonar will run CheckStyle, FindBugs and PMD, as well as a few other “plugins” such as Cobertura (code coverage) by default for Java projects. The main added value, however, is that it stores the history in a database. You can then see the trend. Are you improving the code base or are you doing the opposite? Only a tool with memory can tell you that.

Why No?

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want to spend their time fixing, upgrading (or waiting on it) those libraries (e.g. for Java 8), which for example uses outdated libraries.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.

Answer –

SonarLint is an extension to your favorite IDE that provides on-the-fly feedback to developers on new bugs and quality issues injected into their code.

Starting with SonarQube 4.2, multi-language projects are supported.

This automatically happens when sonar.language is not set.

See sample project here: https://github.com/bellingard/multi-language-project

try something like this:

sonar.exclusions=src/java/test/**

sonar.exclusions=system/**, test/**, application/third_party/**, application/logs/**
