build path between different plugins [message #252290]

Hi,

I've got plugin A with class whose method returns an object.

This object extends a class contained in a specific .jar file contained in a
sub-directory of plugin A. I do not own this jar file and do not wish to
have its source.

Now plugin B calls plugin A's method and receives an instance of the object.

How do I specify a build path for plugin B so as to be able to use plugin
A's object? Currently eclipse marks an error saying "The project (i.e.
plugin B) was not built since its build path is incomplete. Cannot find the
class file for [the base class contained in plugin A's .jar file]" . This
looks as though plugin B needs a reference of plugin A's jar file in order
to use the extended object. How can I have such a reference without relying
on where plugin A is specifically going to be kept?

Thanks,

Robbie Jameson

Go to the Java Build Path property page for the plugin A project. Select
the Order and Export tab. Check the .jar file in question. This allows
dependent projects to reference this jar as well.

Note that this will only allow you to compile plugin B. In order for
plugin B to reference the .jar file at run time, it needs to be specified
properly in the plugin.properties file.
