  Every time when doing an update of the pom.xml file and then
  update project, get a popup with the above error.
  
  
  Using Spring 3.0.5 and JAX-WS 2.2 in a web module with @Resource
  when the build and merge error is encountered.
  
  Local fix:
  
  In this specific user web/servlet application it was enough to
  replace @Resource annotation, for injecting spring bean, with
  @AutoWire and @Qualifier; however, there is no general
  workaround.
