You plug-in depends on the plug-in org.eclipse.ui.forms is that plug-in
available at runtime? In your launch configuration there is a "Plug-ins"
tab which gives you several ways to indicate what plug-in your plug-in(s)
need. For example we are using the "Choose plug-ins and fragments to
lauch from list". When I create a new launch configuration or change a
project's dependent plug-ins, what I do is press the "Deselect All"
button, check the workspace plug-ins that are part of this launch and then
press the "Add Required Plug-ins" button.

I hope that helps,

Ian
