Check code quality with sonarqube

SonarQube is an analysis tool code that allows you to automatically check the quality of the code based on the specified rules and standards. It's powerful a tool that can be used both for individual projects and for projects with a large volume code.

Installing SonarQube on Ubuntu is pretty straightforward. At first Java must be installed if it is not already installed. Next, you need to download SonarQube from the official website, unpack it and set up the database. After that, you need to edit the SonarQube settings file, so that it uses the database correctly. Finally, you can start SonarQube and access web application interface through a web browser.

Using SonarQube can help improve your code quality and detect possible problems before they appear in production. Also SonarQube can be used for automatic code validation in the continuous integration and delivery (CI/CD) process.

Installing SonarQube on Ubuntu can be done like this:

1. Install Java Before installing SonarQube, you need to make sure that Java is installed on your computer. If Java is not installed, you can install it like this:

sudo apt update
sudo apt install default jdk

1. Download and install SonarQube You can download the latest version of SonarQube from the official website: https://www.sonarqube.org/downloads/. Then you need unpack the archive using the command:

sudo tar xzf sonarqube-<version>.zip -C /opt

Replace <version> with the version you want you have uploaded.

1. Set up the database SonarQube uses a database to store information about projects and analysis results. You can use a PostgreSQL, MySQL or Oracle database. Install one of them and set it up.
2. Configure SonarQube Edit the file /opt/sonarqube/conf/sonar.properties and change the database settings on their own.
3. Launch SonarQube Start SonarQube with the command:

sudo /opt/sonarqube/bin/linux-x86-64/sonar.sh start

SonarQube will run on port 9000. You can get access the SonarQube interface by navigating in a web browser to http://your_address:9000.

To check the quality of the code through SonarQube, you need to do the following steps:

1. Install and configure SonarQube following the instructions above.
2. Run code analysis
   • Download and install the SonarScanner client application (https://docs.sonarqube.org/latest/analysis/scan/sonarscanner/).
   • Add the configuration file sonar-project.properties to root directory of your project (https://docs.sonarqube.org/latest/analysis/analysis-parameters/).
   • Run the command sonar-scanner in the root directory your project.
3. View analysis results
   • Go to the SonarQube interface available in a web browser at http://your_address:9000.
   • Open your project page to see the results analysis.
   • Assess code quality based on error reports, warnings, code coverage, and other metrics provided by SonarQube.
