Question

在项目上运行mvn -e enunciate:docs时，我得到了以下错误：

error: [core] java.lang.StackTraceElement: A TypeDefinition must have a no-arg constructor or be annotated with a factory method.

我的java文件在任何地方都没有被提及。有没有办法找出是哪个文件导致了问题？

我还在启用了-X选项的情况下运行了该命令，我得到的唯一调试消息是[class name] is a potential schema type definition, but we're not going to add it directly to the model. (It could still be indirectly added, though.)类型

知道哪里出问题了吗？

Answer 1

Enunciate正试图将java.lang.StackTraceElement视为类型定义。你必须有一个访问器或者一些返回异常的东西。您可以让Enunciate输出您可以遵循的“引用跟踪”，以确定哪个属性将包含java.lang.StackTraceElement作为类型定义：

  <enunciate includeReferenceTrailInErrors="true">
    ...
  </enunciate>
