java - Eclipse Activiti 中的 BPMN 错误

标签 java eclipse activiti bpmn

我正在尝试使用 Activiti eclipse BPMN Designer 5.9 制作一个简单的 Hello world 应用程序。我在 eclipse 中创建了一个 activiti 项目，并将 check.bpmn 图添加到 src/main/resources 文件夹，将 .java 添加到 src/test/java ，将 activiti.cfg.xml 文件添加到 src/test/resources 文件夹。该应用程序只是假设向控制台显示警报“Hello”，但我似乎无法让它执行此操作。下面是我用来运行应用程序的所有文件。我不知道我错过了什么。我已经安装了 Activiti Eclipse BPMN 2.0 设计器。

更新:

我已经添加了jar文件 enter image description here

错误:

最佳答案

错误

Invalid escape sequence (valid ones are \b \t \n \f \r \" \' \ )

告诉您您的字符串无效。

private String filename = "C:\Users\User\workspace\Proj\src\main\resources\diagrams\Check.bpmn";

应该转义

private String filename = "C:\\Users\\User etc...";
