java - 调试 jaxb2 maven 插件

Question

使用 maven-jaxb2 插件从 xsd 生成 Java 代码时出现以下错误，从命令行使用 xjc 一切正常。有人知道如何调试 maven-jaxb2 插件吗？

为了解决当前的问题，您应该像这样更改导入:

<xs:import schemaLocation="schemas.microsoft.com.2003.10.Serialization.xsd" namespace="http://schemas.microsoft.com/2003/10/Serialization/" />
<xs:import schemaLocation="schemas.microsoft.com.netservices.2011.06.servicebus.xsd" namespace="http://schemas.microsoft.com/netservices/2011/06/servicebus"/>  

这不是错误，但 schemas.microsoft.com.netservices.2011.06.servicebus.xsd 中的声明太多。

我个人不会声明/导入任何我不使用的东西，以保持架构简单。

我将 xjb 文件移至与 xsd 文件相同的目录，因此架构位置现在有效。
