Getting Started

Installation

The easiest way to install the SonarLint plugin is to search the marketplace from the IDE.

Go to File > Settings:

Then select the Plugins > Marketplace tab:

Then click OK and restart the IDE to finalize the installation.

You can now enjoy SonarLint!

Offline installation

In case you want to install SonarLint offline, you need to first get access to the plugin zip file.

You can download official versions on the marketplace from this page. Sometimes an ad-hoc version can be built mainly for debugging purposes when a user reports a bug on our community forum.

To install the zip, you can go to File > Settings > Plugins, click on the wheel at the right, then Install Plugin from Disk...

First taste of SonarLint

Let's analyze a first source file and see what SonarLint can bring.

Copy paste this Java code snippet in a project. It contains a code smell because of duplicated methods:

package org.mycompany;

class MyClass {
  private static final String CODE = "XXX";

  public String calculateCode() {
    doTheThing();
    return CODE;
  }

  public String getName() {
    doTheThing();
    return CODE;
  }

  private void doTheThing() {
    // do it
  }
}

If you open this Java file within the editor, you should see SonarLint reporting the issue by highlighting the text range.

You can hover on the highlight to get a short description of the issue. Clicking on the lightbulb that appears in the left margin will reveal a tooltip containing one or more options, including the option to open a detailed Sonar Rule Description.

Sonar Rule Descriptions

Simply select an issue in the SonarLint view or choose SonarLint: Show rule description from the tooltip to open the Rule tab. Here you will find a brief explanation of the rule as well as Noncompliant and Compliant code samples.

SonarLint for IntelliJ supports syntax highlighting. In addition, users are able to visualize a diff view for the non & compliant code sample which should help you fix your issue. Note that diff highlighting is only available for rules descriptions migrated to the new format, and we're progressively migrating all existing rules to the new format.
