Re: [pde-dev] Determining API Usage within vs. between Plug-ins

Your approach sounds reasonable, so I would double check your setup.  Make 
sure there are no resolution errors in the report, ensure packages are 
properly exported as API, and report settings are correct.

Hello,

Problem: The ANT api usage task seems to work fine if I compare an api
producer in one jar file (say p1.jar) with an api consumer in another
jar file (say c1.jar). However I want to see instances of api usage **
within ** p1.jar itself. For example if p1.jar contains /src/test and
/src/demo packages then I want to see how those packages use the other
code within the jar there is no easy mechanism to support this and my
approach (below) does not work.

Approach:

1. The jar of interest is the open source jfreechart project whose
jfreeChart_1.0.13.jar contains org/jfree/chart/demo package and then
everything else org/jfree/chart/<all other packages>.

2. I created two plugin projects with API tooling enabled as follows:

a) use the source code in org/jfree/chart/<all other packages> to make
a plugin and expose all the packages as a public api in the manifest
file. Call this plugin noDemo_plugin.

b) use the source code in org/jfree/chart/demo to make a different
plugin that imports/has a dependency on the plugin created above
(noDemo_plugin). Call this new plugin justDemo_plugin.

c) Export both noDemo_plugin and justDemo_plugin as deployable plugin 
projects.

3. Run the ANT api usage task on the plugins from 2c above.

Results:

Actual Result:  ANT tasks runs successfully but does not contain any
actual data.
Expected Result: Report showing instances of how justDemo_plugin makes
use of the API exposed by noDemo_plugin


Any suggestions or recommendations are welcome.

Thanks,
-pkapur
