[tycho-user] How to get access to "StructuredTextEditor" in my plugin, a

["David M. Karr" <davidmichaelkarr@xxxxxxxxx>]

I'm working with an existing Eclipse plugin codebase that I'm still 
learning how to work on.  I've actually managed to implement some fixes 
and get them integrated, but I'm having an issue with the next task, and 
this is likely just a simple thing with working on Eclipse plugins.

I'm adding a new "source page" to the plugin, which is already a 
multi-page editor.  This new page will be very similar to the "Effective 
POM" view in M2E, so I'm modeling it off of that.

M2E uses an "IEditorPart" which is a 
"org.eclipse.wst.sse.ui.StructuredTextEditor".  I see that I don't have 
access to that class in my plugin, so I'm guessing I have to add a new 
dependency to my target platform file, or perhaps to my "plugin.xml" file.

At this point, I think my problem is that I don't know which bundle has 
this class. Is there a general strategy for figuring out which bundle 
has particular classes?  I tried looking at the M2E source for a clue.  
In the "plugin.xml" for the project that references this class, I see 
that it depends on "org.eclipse.ui.editors" and 
"org.eclipse.ui.popupMenus".  The project in my codebase already has the 
former.  I don't imagine the latter would be relevant.

I see that "StructuredTextEditor" is found in 
"org.eclipse.wst.sse.ui<version>.jar".  I tried going through the target 
platform GUI for a package that might have this, but I'm only guessing.

Again, I could use "the answer", but I'd rather hear "the strategy".
