org.osgi.framework.BundleException: The activator "my plugin" is invalid [message #66490] Wed, 26 January 2005 21:45 Go to next message

Hi,
I created an eclipse plugin. I usually test the plugin by running it as a
run-time workbench and it works fine in the runtime workbench.

After I am sure that the plugin works, I exported the plugin as Deployable
plugin and put it in eclipse plugins' directory. The menus and options all
showed up when I load eclipse. However, when I try to run it, there was an
error popup saying that the class needed is not found. When I check the
log file, it gives me the exception : "org.osgi.framework.BundleException:
The activator "my plugin" is invalid"

anybody knows what's happening?

Thanks in advance,
Erwin

Hi Erwin,

try to delete eclipse/configuration folder and restart.
The folder contains a cache of exsiting plugins and will be recreated during
next startup.

If it's "out of sync" with the content of the plugin folder there are really
strange and not really understandable errors.
So this might alway happen when you "install" a new plugin by dropping it
into the plugin folder.

Best regards
Eckart
