requirement is a plugin.
in the plugin manifest (plugin.xml) an extension to org.eclipse.core.runetime.products has to be created, in which Product Id, name and description have to be indicated.
create a Product in the menu with data file/new/other/plugin Development/Product Configuration (the easiest way is out of „use a launch configuration“). Indicate the Product Id there like in the Plug-in.
If a Splahscreen is desired, then a file „splash.bmp“ can be filed in the root-directory of the plugin and the Plug-in can be chosen in the register Splash of the Product-editor.
last, the product can be exported (file/Export or directly in the ProductEditor).
now, you can start the exe-file.
