How to Integrate SonarQube into IDEA for Pre‑Commit Code Quality Checks
This guide walks you through setting up SonarLint in IntelliJ IDEA, configuring the SonarQube server and project, and using the tool to automatically detect coding standards violations, potential bugs, complexity issues, duplication, and comment problems before committing code.
1. Goal
Integrate Sonar code inspection so that code is checked before committing, avoiding post‑commit reviews. Sonar evaluates seven quality dimensions; developers should focus on the first five: coding standards, potential bugs, complexity, duplication, and comment quality.
2. Prerequisites
SonarQube instance already deployed and a JDK 8 (JDK 7 also works) environment.
3. Install Plugin
In IDEA open Settings → Plugins, search for “SonarLint”, install it and restart the IDE.
4. Configure Project
1) Configure Server
Add the Sonar server address (usually an internal company URL) in the dialog.
2) Select Project
After the server is set, the available Sonar projects are listed; choose the desired one.
When configuration is complete, the Sonar panel appears in the lower‑left corner of IDEA.
