SonarQube provides the capability to check the health of an application and also to highlight issues newly introduced.SonarQube addresses not just find bugs but also coding rules, test coverage, duplications, API documentation, architecture, and complexity, providing all these details in a dashboard. It gives you a moment-in-time snapshot of your code quality today, as well as trends of lagging and leading quality indicators. SonarQube not only addresses core developers and programmers but, also project managers and even higher managerial levels due to the management aspect it offers. The Basic concept of SonarQube is a set of requirements that tell whether or not a new version of a project can go into production.

Steps to implement sonarQube in the maven project:

1. Download the sonarQube server from the link -"https://www.sonarqube.org/downloads/". And then extract it.
2. Go to your maven project then add the following dependency:

    <dependency>
        <groupId>org.codehaus.sonar</groupId>
        <artifactId>sonar-maven-plugin</artifactId>
    </dependency>

3. Also, add the following profile in your pom.xml:

      <profiles>
        <profile>
            <id>sonar</id>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
            <properties>
                <!-- Optional URL to server. Default value is http://localhost:9000 -->
                <sonar.host.url>
                  http://localhost:9000
                </sonar.host.url>
            </properties>
        </profile>
     </profiles>

4. Go to "xyz/sonarQube/sonarqube-7.4/bin/Linux-x86-64(OS)" open it into the terminal. Then run the "./sonar.sh start" command to start the sonar server. The default port of the sonarQube server is 9000. You can change it according to your requirements.
5. Then go to your browser open sonarServer using localhost:9000.
