- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我正在构建一些测试 BPMN 2.0 模型并将它们保存到 xml 文件,在一个 Java 项目中,按照官方提供的示例doc ,在本例中为示例 2。
我在我的 pom 中导入了 lib,如下所示:

我终于通过切换到流畅的模型构建器 API 使其工作,遵循这个 https://blog.camunda.com/post/2014/02/the-new-camunda-bpmn-model-api/
