How to Run a SonarQube Scan Locally in 2025

Running a SonarQube scan locally is essential for developers who aim to ensure code quality and maintainability before pushing their changes. In 2025, SonarQube continues to be an indispensable tool for static code analysis. In this comprehensive guide, we’ll walk you through the steps to run a SonarQube scan locally, helping you to identify bugs, vulnerabilities, and code smells early in the development process.

Why Use SonarQube Locally?

Running SonarQube locally offers several advantages:

• Immediate Feedback: Quickly identify issues in your code before they make it to the shared repository.
• Enhance Code Quality: Enforce coding standards and best practices locally.
• Efficiency: Integrates seamlessly into your development workflow.

Prerequisites

Before running SonarQube locally, you need to set up a few prerequisites:

1. Java Runtime Environment (JRE): Ensure that you have Java 11 or later installed on your system.
2. SonarScanner: Download and install the SonarScanner CLI for your operating system.
3. SonarQube Server: You need access to a SonarQube server. This could be a locally managed instance or a remote server.

Step-by-Step Guide to Run SonarQube Locally

Follow these steps to execute a SonarQube scan locally:

Step 1: Install and Configure SonarQube Server

If you don’t already have a SonarQube server, you can install it locally:

1. Download the latest version of SonarQube from the official website.
2. Extract the downloaded files and navigate to the extracted directory.
3. Start the SonarQube server: bash ./bin/<OS>/sonar.sh start Replace <OS> with your operating system (e.g., linux-x86-64, macosx-universal-64). ### Step 2: Configure SonarScanner 1. Download and unzip the SonarScanner for your operating system. 2. Add the bin directory of SonarScanner to your PATH environment variable. 3. Create a sonar-project.properties file in the root of your project directory with at least the following configuration: - sonar.projectKey - sonar.sources ### Step 3: Run the SonarQube Scan In your project directory, run the following command to execute the scan: bash sonar-scanner

This command will analyze your project based on the configurations in your sonar-project.properties file.

Step 4: Review the Results

Once the scan is complete, open your web browser and go to the SonarQube server’s dashboard (e.g., http://localhost:9000). Review the results to identify any issues and potential improvements in your code.
