javax.persistence 不存在但安装在 maven

Question

I didn't get an answer when I googled it.

Currently, JDK is using 1.8. JPA Plugin is also installed.

I want to use Persistence, but I can't currently use it with the following error.

(but It is really questionable why importing is possible.)

As a result of Googling, many of the answers were maven refresh, etc.

This didn't work for me.

waiting for your answer.

Thank you very much!!

Make sure you're using JDK and not JRE. Enter File > Project Structure > SDKs. Also try to add this dependency from the link: https://mvnrepository.com/artifact/javax.persistence/javax.persistence-api/2.2
