Ho to make packages in my feature available to plug-in developers [message #461122]

A few of the plug-ins within my feature define interfaces and abstract
classes that should be visible to plug-in developers after they have
installed the feature and added my plug-ins as dependencies. However, the
classes do not appear to be available unless, after installing the
feature, I go to the plug-ins view and import the plug-in as a source or
binary project. For other plug-ins, such as org.eclipse.ui, adding the
plug-in as a dependency in my plug-in project is all I need to do to be
able to use the packages/classes that org.eclipse.ui exports. What am I
doing wrong? (For now, all packages in all of my plug-ins are in the
"Export Packages" list and "visible to downstream plug-ins" is selected).

Hi Dan,

In the plugin.xml file, go to the runtime subtab. There add all the
packages that you want to expose to other plugin developers.

Hope this solves your problem. :)

Regards,
Krishna

Krishna,
All of my packages are already listed under the Exported Packages section
on the Runtime tab. Any other ideas?

Expose them in your plugins, not your features.

Andy, I'm not sure what you mean. For each plugin in my feature, I have
gone to the plugin.xml file and on the Runtime tab I have selected all of
the packages in my project. I then created a feature project and included
my plug-ins, but that seems to be independent of what gets exported.

Steps to reproduce this problem. I am using Eclipse 3.2. Create a new
plug-in project, TestExport, use the defaults (targeted to run with
Eclipse 3.2). Click next.
 
Uncheck "this plug-in will make contributions to the UI". Click next.
 
Uncheck "Create a plug-in using one of the templates".
 
In your new plug-in project, create a new class, such as MyTestClass.java.

 
Be sure to list the package under the Exported Packages on the Runtime
tab.
 
Export the project using the export wizard for Deployable plugins and
fragments to a zip file.
 
Extract the zip file into an eclipse installation. Create a new plug-in
project, TestImport, and list the TestExport project as a dependency.
Create a new java class and try to reference the MyTestClass. I cannot
reference the MyTestClass. Am I doing something wrong?
