java - Apache Isis SimpleApp 原型(prototype) - 干净运行类路径错误

Question

我正在尝试使用此 mvn 命令运行从原型(prototype)生成的 Apache Isis 应用程序:

mvn archetype:generate  \
-D archetypeGroupId=org.apache.isis.archetype \
-D archetypeArtifactId=simpleapp-archetype \
-D archetypeVersion=1.6.0 \
-D groupId=com.mycompany \
-D artifactId=myapp \
-D version=1.0-SNAPSHOT \
-B

我已经按照这个screencast启动了Jetty应用服务器在我的 IntelliJ Idea 中，但当我尝试列出所有“SimpleObjects”时，我不断收到错误。

从原型(prototype)生成项目后是否还需要添加其他依赖项？

感谢您的帮助。

Answer 1

没有任何其他依赖项，但有一个问题:您是否正确设置了 datanucleus 增强器任务？这通常是问题所在。请参阅Apache Isis网站了解更多详情。
