Working with Build Tools

与 Eclipse 类似，IntelliJ 并不为编辑 Maven/Gradle 配置文件提供可视化形式。

Like Eclipse, IntelliJ does not provide visual forms for editing Maven/Gradle configuration files.

一旦你导入/创建了你的 Maven/Gradle 项目，你就可以直接在文本编辑器中编辑其 pom.xml/build.gradle 文件。

Once you have imported/created your Maven/Gradle project, you are free to edit its pom.xml/build.gradle files directly in the text editor.
