title: "Cannot resolve symbol" in XML files in IDEA
body: <p>Suddenly I am getting the red stylings of IDEA letting me know that it cannot resolve my JSP paths in my struts-config.xml file. E.g., I get "Cannot resolve symbol 'Definition /WEB-INF/pages/healthCheck.jsp'" when I mouseover the path in the following forward:</p>
  
  <pre><code>&lt;action path="/monitor/lb-healthcheck"
          type="com.rc.mexp.action.HealthCheck"
          scope="request"&gt;
      &lt;forward name="success" path="/WEB-INF/pages/healthCheck.jsp"/&gt;
  &lt;/action&gt;
  </code></pre>
  
  <p>In my view IDEA is displaying "/WEB-INF/pages/healthCheck.jsp" in red. The code builds fine, as normal, but IDEA suddenly doesn't know how to resolve it. Can't find anything useful in a Google search. To reiterate, this was all fine but is now fekachteh. I don't think I did anything that could have caused this. I tried restarting IDEA, invalidating caches, and re-specifying the path to JVM, but none of these things fixed it. I am running 9.0.4 (I know, I know) on Snow Leopard. </p>
  
  <p>So the code works fine, but it's inconvenient IDEA not knowing how to get to my JSPs. I would greatly appreciate any help fixing this. Thanks.</p>
