 Code style is the thing you have to consider when you submit pull request for DolphinScheduler. We using [Checkstyle](https://checkstyle.sourceforge.io), a development tool to help programmers write Java code that adheres to a coding standard, in CI to keep DolphinScheduler codebase in the same style. Your pull request could not be merged if your code style checker failed. You could format your code by *Checkstyle* in your local environment before you submit your pull request to check code style. The activation step as below:

You could find configuration file in the path `style/checkstyle.xml` after you clone repository from Github.

Prepare Checkstyle configuration file: You could download it manually by [click here](https://github.com/apache/dolphinscheduler/blob/3.0.4/style/checkstyle.xml), but find it in DolphinScheduler repository would be a better way. You could find configuration file in the path `style/checkstyle.xml` after you clone repository from Github.
 
 2. Download Checkstyle plugins in Intellij IDEA: Search plugin by keyword **CheckStyle-IDEA** or install in [this page](https://plugins.jetbrains.com/plugin/1065-checkstyle-idea). You could see [install plugin](https://www.jetbrains.com/help/idea/managing-plugins.html#install_plugin_from_repo) if you do not know how to install plugin in Intellij IDEA

 当你向 DolphinScheduler 提交 pull request 的时候 code-style 是你不得不考虑的问题。我们在 CI 中使用 Checkstyle [参考](https://checkstyle.sourceforge.io/)来保持代码风格的统一,它是一种帮助开发者编写遵循编码规范的 Java 代码开发工具。如果你的 pull request 没有通过 Checkstyle 的检测,那它将不会被合并到主库中。你可以在提交 pull request 前使用 Checkstyle 来检测或者格式化你的代码。如下的步骤将引领你配置并激活 Checkstyle
 
-1. 准备 Checkstyle 配置文件:你可以点击[这里](https://github.com/apache/dolphinscheduler/blob/3.0.3/style/checkstyle.xml)手动下载,但是我们更加推荐在 DolphinScheduler 代码库中找到它。当你将代码库克隆下来后,你可以在路径 `style/checkstyle.xml` 下找到配置文件
