Re: [platform-ui-dev] PDE: NoClassDefFoundError
|
In fact, this question has been asked and answered
at least 100 hundred times already at the eclipse.platform
newsgroup. By far, the most favorite FAQ.

Hi Timo!
You're right, this isn't the right place to ask this kind of question.
The mailinglists
are intended mainly for those who develop Eclipse and questions like
this are better
asked in one of the newsgroups. They're followed by far more people and
questions like
this will thus be answered much faster.
Anyway, it looks like your plugin.xml is missing the reference to the
org.eclipse.swt
plugin. To fix this, open the plugin.xml with the 'Plug-in Manifest
Editor' and switch
to the dependecies tab. Add 'org.eclipse.swt' to the list of required
plugins. This'll
fix that problem but I guess there will be more missing requirements.
The plugin.xml lists the runtime requirements of your plugin (and
several other things)
while the classpath only lists the compile-time requirements. In
general, it's a much
better idea to make changes to the plugin.xml, then using "Update
Classpath" (on
plugin.xml's context menu) to update the classpath accordingly.
Cheers,
Boris
