Can my Eclipse plugin change the settings of other plugins?

Question

I am working on an Eclipse plugin that should change some settings defined by other plugins, for example. tab size in text editors. Is it possible?

Answer 1

Yes it is possible.

You will need this on the settings page:

setPreferenceStore( new ScopedPreferenceStore( new InstanceScope(), "bundle-name-of-other-plugin" ) );

Or you can do something like here .

FYI, preferences live here:

pathToWorkspace\.metadata\.plugins\org.eclipse.core.runtime\.settings
