+// For Solr, a 'resolve' task is much more complex. There are three folders:
+// lib/
+// test-lib/
+// lucene-libs/
+//
+// There doesn't seem to be one ideal set of rules on how these should be created, but
+// I tried to imitate the current (master) logic present in ivy and ant files in this way:
+//
+// The "solr platform" set of dependencies is a union of all deps for (core, solrj, server).
+//
+// Then:
+// lib - these are module's "own" dependencies, excluding Lucene's that are not present in the
+//       solr platform.
+// lucene-libs - these are lucene modules declared as module's dependencies and not
+//       present in solr platform.
+// test-lib/ - libs not present in solr platform and not included in solr:test-framework.
+//
+// None of these are really needed with gradle... they should be collected just in the distribution
+// package, not at each project's level.
+//
+// Unfortunately this "resolution" process is also related to how the final Solr packaging is assembled.
+// I don't know how to untie these two cleanly.
+//
