(In reply to EPP Error Reports from comment #0) > This is due to a missing uses constraint in org.eclipse.recommenders.jdt; > org.eclipse.recommenders.utils.names is missing. > > Export-Package: org.eclipse.recommenders.jdt; > uses:="org.eclipse.jdt.core, > com.google.common.base, > org.eclipse.jdt.core.dom, > com.google.common.collect", This is ugly. Due to Bug 458845, PDE's "Calculate Uses" functionality cannot calculate the uses constraint (to org.eclipse.recommenders.utils.names) automatically. This makes it *very* easy to reintroduce this bug. In fact, it has been fixed previously already [1], but was reintroduced later.

The class in question (QueryConstruction) invokes org.eclipse.recommenders.jdt.AstBindings.toTypeName(...), but apparently the bundles org.eclipse.recommenders.jdt and com.codetrails.codesearch.rcp have been wired to different versions of the org.eclipse.recommenders.utils bundle. This is due to a missing uses constraint in org.eclipse.recommenders.jdt; org.eclipse.recommenders.utils.names is missing.
