A new Java Project is created. Here Maven is used as the building management tool and a pom.xml file is created to manage the dependent packages. In the Intellij IDE, how to locate the settings.xml when the Maven is a bundled Maven 3? I did the following opertations
IntelliJ IDEA -> Preferences -> Build, Execution, Deployment -> Build Tools -> Maven
and I navigated myself to a place where the Maven home directory can be overwritten and thus the path of settings.xml file can be visible and the settings can be changed outside this Java project scope.
Do I have to overwrite the Maven home directory and prepare a local Maven copy for each Java project? Is there a shortcut in the IntelliJ IDE such that I can have access to the setting files of a bundled Maven?

新建一个Java工程，使用Maven做搭建管理，在pom.xml中规划依赖软件包，在Intellij开发环境中，怎么找到Bundled Maven 3的配置文件settings.xml？
假如我做以下的操作
IntelliJ IDEA -> Preferences -> Build, Execution, Deployment -> Build Tools -> Maven
然后我可以找到到一个页面，在这个页面上整个Maven主目录可以被设置覆盖，这样的话配置文件settings.xml的路径就可见了，settings可以在这个Java项目的范围外被修改。
一定要覆盖Maven的主目录才能修改配置文件的吗，针对每个工程都得下载一次Maven的吗？有没有一种快捷方式在IntelliJ中，可以直接读取捆绑的Maven的配置文件呢？
