Sonarqube Sonar ant任务失败，提供程序org.apache.xerces.jaxp.SAXParserFactoryImpl未找到异常

我正在竹机上执行声纳蚂蚁任务。同样的任务在我的本地机器（ant版本1.9.3和ant版本1.8.2）上运行良好，但在Bambol ant 1.8.2上失败，出现以下错误

我曾尝试将xercesImpl.jar放在ant类路径中

我在运行sonarqube 4.2时遇到类似问题，findbugs会因为缺少解析器而失败。我可以通过将xercesImpl.jar放在[sonar.home]/web/web-INF/lib文件夹中并重新启动服务器来解决这些问题。一旦通过将其他需要的jar放在同一位置解决了所有其他依赖性问题，问题就消失了

希望这有帮助。

我也遇到了同样的问题，也使用了竹子和声纳蚂蚁任务

我发现这是因为我用一个旧的java版本运行了ant。我从1.6切换到1.7，问题就解决了

希望这对将来有帮助。

谢谢。我将很快尝试并让您知道。当我将xercesImpl.jar放入该文件夹时，sonar根本不会启动。我最终能够通过将xercesImpl.jar之外的xml-API.jar放入上述文件夹来解决此问题。谢谢
