我正在用Java开发astah插件。我正在使用astah UML（具有学生许可证）。
我已将以下依赖项添加到pom.xml：
${astahPath}/astah-api.jar
${astahPath}/astah-uml.jar
$ {astahPath} /lib/slf4j-api-1.6.6.jar
$ {astahPath} /lib/logback-loader-1.0.9b.jar
在eclipse的所有工作中，我都能成功构建项目（astah-build）。当我启动astah（astah-launch）时，它将加载我创建的扩展视图，但是当代码到达时：
IPresentation cp = conn.getPresentations()[0]; // conn is a IConnector
cp.setProperty(PresentationPropertyConstants.Key.LINE_COLOR, "#FF0000"); '
控制台打印：
java.lang.NoClassDefFoundError：com / change_vision / jude / api / inf / presentation / IPresentation
具有以下跟踪信息：

我使用ASTAH API中的其他类没有问题。 您能帮我指出这里可能出什么问题吗？
谢谢。
