I'm trying to validate a PDF file with VeraPDF using WCAG2_1 as a validation methodology.

If I change the methodology to another such as PDFA_4, everything works fine, however with WCAG2_1 something goes wrong.

Right now I have the following:

  public void test()
      throws FileNotFoundException, EncryptedPdfException, ModelParsingException, ValidationException {
    VeraGreenfieldFoundryProvider.initialise();
    //PdfBoxFoundryProvider.initialise();
    PDFAFlavour flavour = PDFAFlavour.WCAG2_1;
    PDFAParser parser = Foundries.defaultInstance().createParser(new FileInputStream(
        "/myfile.pdf"), flavour);
    PDFAValidator validator = Foundries.defaultInstance().createValidator(flavour, true);
    ValidationResult result = validator.validate(parser);

    ListIterator<TestAssertion> ltr = result.getTestAssertions().listIterator();
    while (ltr.hasNext()) {
      System.out.println(ltr.next().getErrorMessage());
    }

    assertTrue(result.isCompliant());
  }

pom.xml

  </dependencies>

I have this output:

java.util.NoSuchElementException: PDFAFlavour wcag2 is not supported by this directory.

at org.verapdf.pdfa.validation.profiles.ProfileDirectoryImpl.getValidationProfileByFlavour(ProfileDirectoryImpl.java:104) at org.verapdf.pdfa.validation.validators.ValidatorFactory.createValidator(ValidatorFactory.java:69)

What can I do to support WCAG2_1 methodology?
