Hello, When using Ruta in a non-Workbench setup (in my case, Maven), I don't manage to catch Ruta script errors in a meaningful way. Here is an example:
"aaa\." -> MyAnnotation; // fails because of escaped dot The thrown error is quite uninformative: java.lang.ArrayIndexOutOfBoundsException: -1 at org.apache.uima.ruta.parser.RutaParser.emitErrorMessage( RutaParser.java:365) at org.apache.uima.ruta.parser.RutaParser.reportError(RutaParser.java:386) at org.antlr.runtime.BaseRecognizer.recoverFromMismatchedToken( BaseRecognizer.java:603) at org.antlr.runtime.BaseRecognizer.match(BaseRecognizer.java:115) at org.apache.uima.ruta.parser.RutaParser.file_input(RutaParser.java:680) at org.apache.uima.ruta.engine.RutaEngine.loadScript(RutaEngine.java:1058) at org.apache.uima.ruta.engine.RutaEngine.initializeScript( RutaEngine.java:743) ... Here is the code to reproduce: https://github.com/renaud/annotate_ruta_example/tree/ruta_error_message However, if I paste that script line in the Ruta Workbench, it nicely underlines it in red at the exact location, and even says "Mismatched input". How do I achieve the same programatically (from Java)? Thanks, Renaud
