IntelliJ IDEA - Maven2 -安装

Question

我从私有存储库下载了一个项目，当我尝试安装时，显示了我需要一个Maven2的错误。问题是，当我下载IntelliJ IDEA时，我下载的是提供Maven3的最新版本。

问题是。有没有可能在IntelliJ中改变Maven的版本？

因为其他问题是当我安装项目时，在控制台中显示下一个错误。

Try downloading the file manually from the project website.

Then, install it using the command: 
    mvn install:install-file -DgroupId=org.apache.maven.plugins -DartifactId=maven-install-plugin -Dversion=2.2 -Dpackaging=maven-plugin -Dfile=/path/to/file

Alternatively, if you host your own repository you can deploy the file there: 
    mvn deploy:deploy-file -DgroupId=org.apache.maven.plugins -DartifactId=maven-install-plugin -Dversion=2.2 -Dpackaging=maven-plugin -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]


  org.apache.maven.plugins:maven-install-plugin:maven-plugin:2.2

from the specified remote repositories:
  central (http://repo1.maven.org/maven2)


  org.apache.maven.plugins:maven-install-plugin:maven-plugin:2.2

from the specified remote repositories:
  central (http://repo1.maven.org/maven2)

但我认为问题不在于代理，问题在于repo1.maven.org是为maven3服务的。

IntelliJ IDEA (Mac上的版本2019.1.3 )设置路径以更改maven主目录。
