Why doesn't netbeans see css styles included in jsp via @include?

Question

css

We have a jsp page. With the help we connect header. In the included file with
<%@include file="../include/include.jspf" %>

<link href="${pageContext.request.contextPath}/css/form.css" rel="stylesheet" type="text/css">

add css styles.
In the application, the page is displayed correctly, i.e. styles are included.
But at the same time, in the Netbeans code analyzer, errors are shown that supposedly "Class ____ not found".
Tried to connect via JSTL

<link rel="stylesheet" type="text/css" href="<c:url value='/css/table.css'/>">

He doesn't see it either. How to correctly connect a css file to jsp so that the static analyzer correctly determines the presence or absence of styles?
