Hi Erik, Following your advice, I send my patch for the ANTLR task. It uses a "real" parser to find dependencies between ANTLR files. Attached is a zip containing new sources for ANTLR task, extended test set (that makes the current task fail) and diffs against 1.5.1beta.
If there are any problems, I am ready to fix them.
