解决IDEA Maven Cannot reconnect

我的idea是2022.2版本，我的电脑是Mate book14 windows11的版本。jdk1.8的版本
然后经常遇到这种情况，

点击maven的reload按钮，会抛出以下异常：

java.lang.RuntimeException: Cannot reconnect.

java.lang.RuntimeException: Cannot reconnect.

后来发现是jdk版本选的不对

其原因是因为IDEA的maven中的importing使用的JDK与你实际项目使用的JDK版本不一致,

将JDK 改为自己安装的jdk即可
