使用 maven-jaxb2 插件从 xsd 生成 Java 代码时出现以下错误，使用命令行中的 xjc 一切正常。任何人都知道如何调试 maven-jaxb2 插件？

为了解决手头的问题，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 中有太多声明。

我个人不会声明/导入任何我不用来保持模式简单的东西。

我将 xjb 文件移动到与 xsd 文件相同的目录中，因此架构位置现在有效。

您应该检查命名空间 (tnsn) 是否在 xsd.xml 中声明。如果是，那么它可能是一个无法访问的 xsd 导入，可能会出现这样的错误。否则：http://confluence.highsource.org/display/MJIIP/User+Guide 调试和详细选项可用...
