Document is ambiguous error on executing ruta script.

[raghu298]

I am using below versions:

versions used:
[uimaj-3.4.1]
[uimafit-3.4.0]
[ruta-3.3.0]
[cleartk-3.0.0]

java.lang.IllegalArgumentException: Document is ambiguous, use one of the following instead : org.apache.uima.ruta.type.Document uima.tcas.DocumentAnnotation

@pkluegl Could you please help out what is going wrong and mostly its occurring when it runs in batch.
I don't have any multiple versions too.
and why Ruta thinks that "Document" should be a valid name for "Document" annotation.

I am unable to reproduce the issue on the 3.3.x branch

package org.apache.uima.ruta;

import static java.util.Arrays.asList;

import org.apache.uima.cas.CAS;
import org.apache.uima.cas.Type;
import org.apache.uima.cas.text.AnnotationFS;
import org.apache.uima.fit.factory.TypeSystemDescriptionFactory;
import org.apache.uima.resource.metadata.TypeSystemDescription;
import org.apache.uima.resource.metadata.impl.TypeSystemDescription_impl;
import org.apache.uima.ruta.engine.Ruta;
import org.apache.uima.util.CasCreationUtils;

public class RutaScriptExample {
 private static final String DOCUMENT = "org.apache.uima.ruta.type.Document";

 public static void main(String[] args) {
   try {
     // Create a TypeSystemDescription with a type x.y.z.Document
     TypeSystemDescription tsDesc = new TypeSystemDescription_impl();
     tsDesc.addType(DOCUMENT, "", "uima.tcas.Annotation");

     TypeSystemDescription tsDefault = TypeSystemDescriptionFactory.createTypeSystemDescription();

     TypeSystemDescription tsAll = CasCreationUtils.mergeTypeSystems(asList(tsDesc, tsDefault));

     // Create a CAS with the type system
     CAS cas = CasCreationUtils.createCas(tsAll, null, null);

     // Add some text to the CAS
     cas.setDocumentText("This is a sample document.");

     // Create an annotation of type Document
     Type documentType = cas.getTypeSystem().getType(DOCUMENT);
     AnnotationFS documentAnnotation = cas.createAnnotation(documentType, 0,
             cas.getDocumentText().length());
     cas.addFsToIndexes(documentAnnotation);

     // Define a Ruta script that uses the rule Document{-> ...}
     String rutaScript = "Document{-> NUM};";

     // Apply the Ruta script to the CAS
     Ruta.apply(cas, rutaScript);

   } catch (Exception e) {
     // Catch and handle any exceptions that occur
     System.err.println("An error occurred while applying the Ruta script:");
     e.printStackTrace();
   }
 }
}

@viorell91 suggested on the mailing list to try disambiguating the type in the scripts:

TYPE Document1 = org.apache.uima.ruta.type.Document;
TYPE Document2 = uima.tcas.DocumentAnnotation;

Document1{ -> CREATE(MyAnnotation)};
