However when I added the plugin as one of the dependencies of my application I am unable to import the file.

I get the following error when I tried to search it through "Open Type" in Eclipse as follow

What steps am I missing here ?

Answer 1

Usually it is done like this: in Eclipse go to File -> New -> Plugin Development -> Plugin From Existing Jar Files

Though it might not help in this case: please see this issue: https://java.net/jira/browse/COM4J-57

Answer 2

It sounds like you have not specified which classes are exported by the plugin.

Open the MANIFEST.MF editor for the plugin and select the Runtime tab. In the 'Exported Packages' section click Add and select all the packages which should be available to other plugins.
