Setting generic launch/run configuration in eclipse

When I select a class and choose Ru开发者_Go百科n as, how can have eclipse give sub menu options such as Java application, Android application?

Basically, it's up to the plugin-contributor to set those actions. They are called lanuch-configuration-shortcuts, and unless it was not added in the plugin contribution, it will not be there. Also, lunch shortcuts appear where are configured to appear, so if your current file (content-type) does not match the configuration rule, it will not appear in the Run-As.
