Eclipse Resource Search
You may need an example since you encounter some problems with writing the code of eclipse. It's easier for you to follow the example. The source code of eclipse itself is one of the best example, The problem is how to find these examples quickly.
Quick Search the information of Plug-in.
find Bundles with ExtensionPoint name,subPath,attribute name,attribute value. see example below.
search Eclipse Bundles which implements ExtensionPoint "org.eclipse.ui.viewActions" and with sub path "/viewContribution/action"
search Eclipse Bundles which implements ExtensionPoint "org.eclipse.ui.menus" and with sub path "/menuContribution/command@commandId"
The names of ExtensionPoint and Bundle are related,for example org.eclipse.ui.Actions is defined in org.eclipse.ui of bundle.
but not all of the extension point have this kind of matchup,such as org.eclipse.core.runtime.adapters is defined in org.eclipse.equinox.registry of Bundle.
Search the plugin where the Extensionpoint defined
Input org.eclipse.core.runtime.contentTypes in the search box
