What approach should be to change Eclipse Preferences?
They are stored in <workspace>/.metadata/.plugin/org.eclipse.core.runtime/.settings
But I hope to find Java API and a way to discover any preference ID.

Looked at Eclipse plugins? The M2 plugin can set a lot of project settings, it might inspire. What do you want to achieve? – Thorbjørn Ravn Andersen Sep 30 '14 at 06:18

Is this for a plugin that you are writing or are you trying to change existing preferences of other plugins? – greg-449 Sep 30 '14 at 07:03

Somewhat confusingly there are several APIs a plugin can use for preferences.
If your plugin activator extends AbstractUIPlugin then you can call
IPreferenceStore prefStore = getPreferenceStore();
in the activator to get the preference store for your plugin.
You can also use
IEclipsePreferences prefs = InstanceScope.INSTANCE.getNode("node id");
to get a slightly different interface to the preferences.
There is also the org.eclipse.equinox.preferences.preferences extension point which lets you define an 'initializer' to set the default values for preferences.
