How to deal with the syntax of the jstl tag library (although it runs correctly) in IDEA?

uric:out
JavaWeb,jstl1.2jarlib,.
maven

only those built with this selected one have these problems.
I have also looked up some

wow, I think it would be nice if it could be solved as they say. But it doesn"t work.
now I don"t expect IDEA Nengba to help me complete the jstl automatically, just make sure that the error is no longer displayed, okay? For some reason, it seems that after I restart the server, the code of my jsp page will automatically change back to the page that IDEA thinks is right! This is so fucking awesome.
Thank you

you don't have to go to problems like google, when you encounter this kind of problem, you can basically infer that the progress of the project is not much, right?
reconfigure a java maven web project from scratch
add dependencies to maven

    <dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>jstl</artifactId>
      <version>1.2</version>
    </dependency>

then just wait for loading. There are not so many messy troubles.
I thought there was a problem with IDEA's support for jstl because I went to google and found that a lot of people encountered this problem.
in fact, it's not. Everything you see in search problems is problematic. In fact, there is no problem with IDEA's support for jstl. Maybe there's something wrong with my previous environment.

it is better to add

<%@ page isELIgnored="false" %>
