我正在尝试使用Activiti eclipse BPMN Designer 5.9创建一个简单的Hello world应用程序。我在Eclipse中创建了一个activiti项目，并将我的check.bpmn图添加到src / main / resources文件夹中，并将.java添加到src / test / java，并将activiti.cfg.xml文件添加到src / test / resources文件夹中。该应用程序只是假设向控制台显示警报“ Hello”，但是我似乎无法做到这一点。下面是我用于运行该应用程序的所有文件。我不知道我缺少什么。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

最佳答案
错误
无效的转义序列（有效的是\ 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";
应该逃脱
private String filename = "C:\\Users\\User etc...";
