[news.eclipse.platform.pde] Custom update site problem

[James Williams <jrw502@xxxxxxxxxxxxx>]

Hi all,

I recently decided to create an update site for some plug-ins that I developed and I've having trouble with the update site.  I created two features for my plug-ins and referenced them from my update site project.  Clicking Build All happily packages up my jars with no errors.

When I try to install the plug-ins using the site, however, I get an error.  I added the site to my list of update sites (using the Local option and selecting the update site project directory), and this lists the features available to install.  When I try to install the plug-ins, I get the following error:

Searching around the internet I find a lot of people reporting errors like this to plug-in developers but not answers to what the cause of the problem is.  I'm guessing there's something wrong with my plug-ins rather than the site or features?  Furthermore, the manually adding the jars to the plugins folder works fine.

Any help much appreciated.
