Request Matcher not resolved while migrating spring security from 3 to 4 - spring

Question

I am migrating my spring security from 3.1.4 to 4.1.5. I am using RequestMatcher in my security config to filter out urls.I updated RequestMatcher to the correct package as suggested in Migration document to org.springframework.security.web.util.matcher.RequestMatcher.
I am pointing request-matcher-ref in to point the a custom class which implements RequestMatcher. But i am getting the following error in intellij - Cannot resolve required base class 'org.springframework.security.web.util.RequestMatcher'.
How to resolve this issue.
