Birt UnsupportedFormatException

Question

我使用的是birt版本3.7.0。

我正在尝试创建PDF文件。每次我得到一个错误。

代码：

private byte[] generateAttachment(Map<String, Object> reportParams) throws EngineException {

IReportRunnable design = this.reportEngine.openReportDesign(this.getClass().getClassLoader().getResource(
                                                     ATTACHMENT_PATH).getFile());

// Create a task to run and render the report
IRunAndRenderTask runAndRenderTask = this.reportEngine.createRunAndRenderTask(design);

// Set parent class loader for engine
runAndRenderTask.getAppContext().put(
                     EngineConstants.APPCONTEXT_CLASSLOADER_KEY,
                     CAFInjectorService.class.getClassLoader());

// Set report parameter values and validate
if (reportParams != null)
    runAndRenderTask.setParameterValues(reportParams);
runAndRenderTask.validateParameters();

// Setup PDF renderer
ByteArrayOutputStream outStream = new ByteArrayOutputStream();
PDFRenderOption pdfOptions = new PDFRenderOption();
pdfOptions.setOutputFormat("pdf");
pdfOptions.setOutputStream(outStream);
pdfOptions.setOption(
             IPDFRenderOption.PAGE_OVERFLOW,
             IPDFRenderOption.FIT_TO_PAGE_SIZE);
runAndRenderTask.setRenderOption(pdfOptions);

// Run and render the report
runAndRenderTask.run();
runAndRenderTask.close();

return outStream.toByteArray();
}

我收到以下错误

org.eclipse.birt.report.engine.api.UnsupportedFormatException: The output format pdf is not supported.

编辑:我只有这个birt相关的gradle依赖：

compile group: 'org.ow2.orchestra.eclipse.birt', name:'org.ow2.orchestra.eclipse.birt.report.engine', version:'3.7.0'

我需要再来一杯吗？

编辑2：

新增:compile group: 'org.eclipse.birt.runtime', name:'org.eclipse.birt.runtime', version:'4.4.1'

并在尝试下载依赖项时出现此错误：

Answer 1

我不确定org.ow2.orchestra对BIRT做了什么；我正在使用mt4e将官方的Eclipse BIRT包转换成Maven可以处理的JAR。不幸的是，这是一个相当冗长/复杂的过程：

您需要检查它们是否与某个地方的org.apache.batik.pdf有依赖关系；在我的代码中，捆绑包org.eclipse.birt.runtime就是这样做的。
