title: Missing maven dependencies from deployment assembly
body: <p>I've recently upgraded from eclipse 4.4.2 (Luna) to 4.5 (Mars). My dynamic web project now doesn't include the Maven Dependencies in its deployment assembly "Project->Properties->Deployment assembly".</p>
  
  <p>I can add them manually (using "Project->Properties->Deployment assembly->Add->Java Build Path Entries->Maven Dependencies"), but every time I run "Project->Maven->Update Project Configuration", the Maven Dependencies are removed again.</p>
  
  <p>Note that I run the project using the Apache Tomcat Server within the Eclipse IDE.</p>
  
  <p>I have installed </p>
