title: javax.servlet.http.HttpServlet was not found even if maven dependency exists
body: <p>I have an issue with my Eclipse Neon configuration on my maven project. The issue that appears many times is the following <strong><em>The superclass "java.servlet.http.HttpServlet" was not found on the java build path</em></strong>. I know there were few posts about that and know also that there is two solutions. The first one is to add a Tomcat server on runtime and the second one is to add servlet dependency in the pom.xml. 
  As it's an SVN project, the depedency was already in it and anyone in my team has a Tomcat configured on runtime but the project is building well on their eclipse. 
  Any idea ? </p>
