For instance:\n\n```\n\u003cplugin\u003e\n  \u003cgroupId\u003eorg.apache.maven.plugins\u003c/groupId\u003e\n  \u003cartifactId\u003emaven-checkstyle-plugin\u003c/artifactId\u003e\n  \u003cversion\u003e...\u003c/version\u003e\n  \u003cconfiguration\u003e\n    ...\n  \u003c/configuration\u003e\n  \u003cdependencies\u003e\n    \u003cdependency\u003e\n      \u003cgroupId\u003ecom.puppycrawl.tools\u003c/groupId\u003e\n      \u003cartifactId\u003echeckstyle\u003c/artifactId\u003e\n      \u003cversion\u003e...\u003c/version\u003e\n    \u003c/dependency\u003e\n    \u003cdependency\u003e\n      \u003cgroupId\u003ecom.github.robtimus\u003c/groupId\u003e\n      \u003cartifactId\u003echeckstyle-extension\u003c/artifactId\u003e\n      \u003cversion\u003e...\u003c/version\u003e\n    \u003c/dependency\u003e\n  \u003c/dependencies\u003e\n  \u003cexecutions\u003e\n    ...\n  \u003c/executions\u003e\n\u003c/plugin\u003e\n```\n\n## Eclipse integration\n\nDownload the latest JAR file from Maven Central or the [GitHub release page](https://github.com/robtimus/checkstyle-extension/releases), copy it to Eclipse's `dropins` folder, and restart Eclipse.\n\n## IntelliJ integration\n\nFirst, make sure that you have the [CheckStyle-IDEA](https://plugins.jetbrains.com/plugin/1065-checkstyle-idea) plugin installed. Next, download the latest JAR file from Maven Central or the [GitHub release page](https://github.com/robtimus/checkstyle-extension/releases). Finally, configure IntelliJ to include it as part of its third-party checks:\n\n* Open `Settings...`\n* Open the Checkstyle settings\n* Add the JAR under the `Third-Party Checks` section\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frobtimus%2Fcheckstyle-extension","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frobtimus%2Fcheckstyle-extension","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frobtimus%2Fcheckstyle-extension/lists"}
