解决方案
IntelliJ IDEA --> Preferences --> Build，Execution，Deployment --> Build Tools --> Maven --> Importing -->JDK for importer选择我们已经安装的JDK版本
在这里插入图片描述
如果还是解决不了问题，可以尝试添加如下两个参数：
1）maven -> Importing -> VM options for importer
-Xmx768m -Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true -Djava.net.preferIPv4Stack=true
2）maven -> Runner -> VM Options
-Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true -Dmaven.wagon.http.ssl.ignore.validity.dates=true -Djava.net.preferIPv4Stack=true
