Use this dialog to set the facets of the current project.
You can access this wizard in one these ways:
Facets are used to specify the type of project, add standard libraries, set compiler options, control publishing tasks, set the build path and/or add an annotation processor. The facets that are displayed will vary depending on the type of project. Required facets are shown in boldface. Simply click the checkbox beside the facet name to add it to the current project.
