Adobe XMP library not found

[leticia.l.silva]

Como faço para adicionar esta biblioteca no meu projeto ?

Pois quando  vou gerar meu PDF/A  , ele diz que : Adobe XMP library not found

Este e o meu codigo 

 List<Aluno> alunos = alunoRepository.findAll();        File file = ResourceUtils.getFile("src/main/resources/aluno.jrxml");        JasperReport jasperReport = JasperCompileManager.compileReport(file.getAbsolutePath());        JRBeanCollectionDataSource dataSource = new JRBeanCollectionDataSource(alunos);        JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, new HashMap<>(), dataSource);        JRPdfExporter pdfExporter = new JRPdfExporter();        pdfExporter.setExporterInput(new SimpleExporterInput(jasperPrint));        pdfExporter.setExporterOutput(new SimpleOutputStreamExporterOutput(new FileBufferedOutputStream()));        SimplePdfExporterConfiguration configuration = new SimplePdfExporterConfiguration();        configuration.setPdfaConformance(PdfaConformanceEnum.PDFA_1A);        configuration.setIccProfilePath("src/main/resources/icc/sRGB_IEC61966-2-1_black_scaled.icc");        setDefaultPdfFontEmbedded();        pdfExporter.setConfiguration(configuration);        pdfExporter.exportReport();        {        }        return ("PDF/A criado com sucesso !");    }}
