Question

使用maven-jaxb2插件从xsd生成Java代码时出现以下错误，它在命令行中使用xjc运行良好。谁知道如何调试maven-jaxb2插件？

Answer 1

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，但在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schemalocations现在有效。

您应该检查是否在xsd中声明了命名空间（tnsn）。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...
