Hello,
I have some plugins, which work fine in the runtime environment. I
exported them to an archive.
To test this archive, I extracted it to an empty eclipse directory,
added the .eclipseextension file and used this as an install location
for a fresh instance with its own workspace and configuration.
Everything seems to be fine: The Contributions show up in the UI and all
plugins are listed in the plugin registry.
But when I run some of the Actions of the plugins, I keep getting
NoClassDefFoundError(see below).
So I tried (from the test instance) to import the plugins in the
workspace, and again start a runtime with them -this worked! So the same
plugins to not work when included via install site, but do work in a
runtime.
The errors seem to refer to the same plugin(on which all the others
depend), this one seems not to be found. But it is there..and exporting
all classes via <export name="*"/>.
Thanks for any help.
Frank
