Error description

• Abstract:
  
  Attempts to removing the .apt_generated folder from a web
  project causes the project to become non-single root and results
  in a degradation of publishing performance to a local WebSphere
  Application Server instance.
  
  Problem:
  
  1. If Annotation processing is enabled, a Dynamic Web project
  has the folder .apt_generated added to these files:
  
  .classpath
  .settings/org.eclipse.wst.common.component
  
  2. If you delete the .apt_generated folder from the Enterprise
  Explorer or from the Project Explorer (as opposed to the
  Navigator View) then:
  - The folder is automatically re-added
  - The folder is no longer in the .classpath file
  - The folder is still in the
  .settings/org.eclipse.wst.common.component file.
  
  3. If you enable the Project Structure Validator
  (Windows?Preferences?Validation), the following warning is
  displayed:
  
  Broken single-root rule: The source path '/.apt_generated' must
  map to a Java source folder    org.eclipse.wst.common.component
  
  4. If you publish the project a local WebSphere Application
  Server, the process is slower because the project is non-single
  root.
  
  5. If you look at the Assembly and Deploy property of the
  project, the folder .apt_generated is not shown, so you cannot
  detect the mismatch between .classpath and
  .settings/org.eclipse.wst.common.component
  
  Local fix:
  
  There is no known workaround at this time.
