解決方法

1.IntelliJ IDEA --> Preferences --> Build，Execution，Deployment --> Build Tools --> Maven --> Importing -->JDK for importer選擇我們已經安裝的JDK版本

如果還未解決，執(zhí)行下面兩個操作

2.maven -> Importing -> VM options for importer

-Xmx768m -Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true -Djava.net.preferIPv4Stack=true

3. 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

這里JRE原本選的是Project JDK，我改成了JAVA_HOME，不知有沒影響，最后是成功不報錯了。

總結

以上為個人經驗，希望能給大家一個參考，也希望大家多多支持腳本之家。
