ionsAffectAction</code> returns
 true for that command. The menu items correspond to available configurations; when selected, an item runs the
 project action once with that configuration in effect without changing the active configuration. Java SE
 projects enable this mode for the <b>Run Main Project</b> and <b>Debug Main Project</b> buttons.

 A menu item <b>Set Main Project Configuration</b> is also added to the <b>Build</b> menu with similar
 semantics.
