hi,

I have developed a plugin which works fine when i run it on the runtime
workbench but when I have packaged it and deployed it on eclipse, and when
I activate a control thats supposed to open up a ContainerSelectionDialog,
I get a NoClassDefFoundError, The stack trace is as follows,

java.lang.NoClassDefFoundError:

Does you plugin have org.eclipse.ui.dialogs as a required bundle in the
MANIFEST?

I met a similar situation, and I DO add <requires> : When I'm trying to
patch someone's plugin(not known the author), I added <import
plugin="org.eclipse.core.resources"/> on its manifest to use
ResourcesPlugin, but it does not work.(NoClassDefFoundError:
ResourcesPlugin... when acvitated it on runtime workbench)

What's wrong with it?

hi,

yes it has the org.eclipse.ui.dialogs in the required bundle of the
MANIFEST.MF.

I vaguely remember that your described problem occured in cases,
when export was done. Please try the following: Before doing your export
go into your filesystem and delete manually **all** files from the
configuration directory, where you want to export in! There exist cases
where the export process does not completely clean the target directory.

Hope that helps,
