For my own reference:

  • Create a new GWT-Project
  • Give it a standard Plug-In name (e.g. de.jastram.gwtexample)
  • Give the Project the Plug-In Nature (Right-click on Project > Configure > Convert to Plug-in Projects…)
  • Add Dependency to de.jastram.jettyrunner
  • Add Extension de.jastram.jettyrunner.warrunner
  • Add a war-element
  • That’s it – don’t forget to compile.
