SonarLint for Eclipse

SonarLint helps you deliver Clean Code in your IDE.

Installing and using

See https://docs.sonarsource.com/sonarlint/eclipse/getting-started/installation/ and https://marketplace.eclipse.org/content/sonarlint

For offline installation and older versions see the update site archive at https://binaries.sonarsource.com/?prefix=SonarLint-for-Eclipse/releases/

Have Questions or Feedback?

For SonarLint support questions ("How do I?", "I got this error, why?", ...), please first read the FAQ and then head to the SonarSource forum. There are chances that a question similar to yours has already been answered.

Be aware that this forum is a community, so the standard pleasantries ("Hi", "Thanks", ...) are expected. And if you don't get an answer to your thread, you should sit on your hands for at least three days before bumping it. Operators are not standing by. :-)

Contributing

If you would like to see a new feature, please create a new thread in the forum "Suggest new features".

Please be aware that we are not actively looking for feature contributions. The truth is that it's extremely difficult for someone outside SonarSource to comply with our roadmap and expectations. Therefore, we typically only accept minor cosmetic changes and typo fixes.

With that in mind, if you would like to submit a code contribution, please create a pull request for this repository. Please explain your motives to contribute this change: what problem you are trying to fix, what improvement you are trying to make.

Make sure that you follow our code style and all tests are passing.

Development setup in Eclipse

There are a few requirements for developing next to basic knowledge of Maven, Tycho and Eclipse plug-in development:

  • Eclipse IDE for RCP and RAP Developers (includes m2e, PDE)
  • RedDeer to run ITs

Normally, m2e will automatically suggest to install missing connectors (Tycho configurators, ...) or wants to configure missing lifecycle mappings. This can all be done later.

  1. Run mvn clean verify -DskipTests on the command line to fetch artifacts referenced in the parent pom
  2. In Eclipse, import the project root as a Maven project
  3. In Eclipse, import the project root of the ITs as a Maven project and add them to the main project
  4. Open target-platforms/dev.target with the target platform editor
    • Click Set as Target Platform (or Reload Target Platform) in the top-right corner

At this point you should be all set. Following the explanations here may help.

Running

Open plugin.xml of org.sonarline.eclipse.core (for example), and see the Run and Debug buttons in the top-right corner.

Running plugin unit tests

In Eclipse:

  1. Create a run configuration by running a test class first with Run As... / JUnit Plug-in Test

  2. Edit the configuration

    • On the Test tab, uncheck Run in UI thread
    • On the Main tab, under Program to Run, select Run an application with value [No Application] - Headless Mode

With Maven:

mvn clean verify

Running ITs

Please see the README.md inside the its folder!

Adding a dependency

We should avoid adding external dependencies, as we want all bundles we provide in our update site to be signed, and we don't want to sign third-party components. Third-party libs should be bundled/shaded into our own plugins.
