[platform-update-dev] Problems running through tutorial at http://dev.ec

["Steve Woolley" <SWOOLLEY@xxxxxxxxxx>]

Hi Folks,

I've just been working through the very useful tutorial in the document
titled, "PDE Support for Eclipse Update Site Building" on eclipse.org:

http://dev.eclipse.org/viewcvs/index.cgi/~checkout~/pde-ui-home/working/site-builder.html


I got as far as step 9 in "Creating the site" when I ran into problems.
When I attempted to build the features, I was presented with a message that
looked like:

Problem Occurred
java.lang.NullPointerException

When I attempted the view the Build Log from the Build view, the link
wouldn't open anything.  However, scanning the .log file in my workbench
revealed the following:

!ENTRY org.eclipse.jface 4 2 May 08, 2003 18:44:13.462
!MESSAGE Problems occurred when invoking code from plug-in:
"org.eclipse.jface".

Apologies if this topic has been covered previously on this mailing list,
but I would appreciate some help here.  I'm running a V2.1 SDK (build ID
200303272130) on Windows 2000.

Many thanks,


Steve
