在IDEA右上角
File -> Settings -> Build,Execution,Deployment -> Build Tools -> Maven
我们可以看到自己的Maven配置信息
如果不是自己配置的Maven，这样改 修改C:\Users\lx\AppData\Roaming\JetBrains\IntelliJIdea2020.1\options\project.default.xml文件，添加下面这段内容
<component name="MavenImportPreferences">
<option name="generalSettings">
<MavenGeneralSettings>
<option name="localRepository" value="D:\Javaweb\apache-maven-3.6.3-bin\apache-maven-3.6.3\repository" />
<option name="mavenHome" value="D:\Javaweb\apache-maven-3.6.3-bin\apache-maven-3.6.3" />
<option name="userSettingsFile" value="D:\Javaweb\apache-maven-3.6.3-bin\apache-maven-3.6.3\conf\settings.xml" />
</MavenGeneralSettings>
</option>
</component>
