2.1 Create a new Workspace file in the same level directory of maven just now, and create a new MavenRepository folder in the file directory, which is used as the local library of maven
2.2 Find settings.xml in conf in the maven directory, open the file with Notepad, and enter the following code:
<!-- 下面是自己设置的本地仓库位置-->
<localRepository>MavenRepository文件位置</localRepository>2.3 Enter the following code in cmd
maven help:system

</mirror>
4. After successful operation,

The following files will appear in the MavenRepository folder
success!
Replenish:
In idea, maven’s local warehouse is still c:/user/.m2/repository. When your idea automatically downloads the package for you, it will not be placed in the location you set, so you need to do it in idea Modification, other development tools should be the same.
Modification location: in file - setting (and file - other settings -default settings), search for maven, modify maven home directory and User settings file,
Change the Maven Home directory to the directory of your own maven program. This must be specified, otherwise the Maven program of idea will be used by default.
Change User settings file to settings.xml in your own maven directory config
Note: local repository If you set up your own maven local repository according to the previous steps, you don’t need to modify it at this time, otherwise you need to manually specify the folder directory of your Jar package.
