Re: [cdt-dev] CDT bundling with RCP app.

[Chris Recoskie <recoskie@xxxxxxxxxx>]

Considering that the CDT provides IDE functionality, trying to use it in an RCP app sort of doesn't make sense, as it relies on such concepts as the Eclipse project/resource model, builders, debugging, etc. etc. It's not a surprise that you would have problems trying to use it that way.

Hi,

I'm trying to bundle CDT along with my RCP app. RCP app runs perfectly fine when 
executed through IDE but fails when executed as product i.e. it throws null 
pointers and SWT exceptions and so on which I don't see when i run my RCP app 
through IDE. 
As far as the RCP app is concerned, it works fine in both the cases, executed 
using ide or as product. But when executed as a product, CDT never works. Even 
if right click in Project Explorer throws SWT and NullPointer exceptions.

I have tried following things,
- handled dependencies
- validated
- have not made any change in CDT code

And here is the stack trace,

Am I missing anything here?
Please provide some pointers. Stuck badly. Any help would be great.

Thanks in advance,
