Code analysis reports

Sonar is one of the most popular quality management tools that gives a complete analysis of a project in terms of lines of code, documentation, test coverage, issues, and complexities. As a developer, we are mainly interested in the following areas:

• Duplicate lines of code

• Lacking comments in the source code, especially in public APIs

• Not following coding standards and best practices

• Finding code complexity

• Code coverage produced by unit tests

In this section, we will discuss Gradle integration with Sonar. The only prerequisite is, the Sonar server should be installed and running.

A prerequisite to run Sonar is to have Java installed on the box. Once prerequisites are met, you can install Sonar in just three simple steps as follows:

1. Download the distribution from http://www.sonarqube.org/downloads/ and unzip it.

2. Open a console and start the Sonar server:

   • On Windows platforms, start $SONAR_HOME\bin\windows-x86-32\StartSonar.bat

   • On other platforms, start $SONAR_HOME/bin/[OS]/sonar...
