Search engine does not find annotation type references in required plug-ins

[subyssurendran666]

Using the search engine to find references of an annotation type does not produce any findings in the required plug-ins of a plug-in project. Take a look at the following search configuration:

SearchPattern pattern = SearchPattern.createPattern(myAnnotationName, IJavaSearchConstants.ANNOTATION_TYPE, IJavaSearchConstants.ANNOTATION_TYPE_REFERENCE, SearchPattern.R_EXACT_MATCH);

IJavaSearchScope scope = SearchEngine.createJavaSearchScope(new IJavaElement[] {myJavaProject}, true);

The above configuration does not find the expected matches of myAnnotationName inside the required plug-ins of myJavaProject. The required plug-ins are binary.

The strange thing is that all references are found when extending the scope to the entire workspace searching for type references:

SearchPattern pattern = SearchPattern.createPattern(myAnnotationName, IJavaSearchConstants.TYPE, IJavaSearchConstants.REFERENCES, SearchPattern.R_EXACT_MATCH);

IJavaSearchScope scope = SearchEngine.createWorkspaceScope();

So it seems that broadening the search space leads to more findings, although IMHO all matches should also be found when the search space is restricted to the respective project only.

The JUnit test case is operating without any issues, so we are now closing the ticket.
