Hello.
Sorry if the problem was solved on this group before but I couldn't find it
anywhere.
I have started developing Taverna plugin based on tutorials on Taverna website.
I have managed to create generic plugin, build and deploy it to dropbox repo. I
am also able to install it in standalone Taverna application. Service is
recognized correctly and installs without errors.
Problems start when I try to add created service to the workflow. From Taverna
I get dialog with: "Uncaught exception …".
Logs say that one class from guava library cannot be found:

This error pops up despite the fact that guava jar is downloaded during plugin
installation process and I can locate it in ~/Libraries/Application
Support/taverna-2.4.0/repository directory. This problem does not occur when I
try plugin from TavernaWorkbenchWithExamplePlugin class.
Does anyone have any idea why this happens? I will appreciate any help.
Best Regards,
Dawid Nejman
