Java 具有相对路径的Jaxb2目录文件

我试图从相当多的XSD生成一些Java代码。它们中的大多数都工作得很好，但是我在使用一个特定的XSD导入另一个具有相对路径的XSD时遇到了问题。例如：

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns:xmpl="http://example.com/this/is/namespace" xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://example.com/this/is/namespace">
    <include schemaLocation="../../0301/required.xsd" />
    <some> ... xml ... </some>
</schema>

---

但它就是不起作用。有人有什么想法吗？

不幸的是，maven-jaxb2-plugin项目在这个问题上有一个公开的问题：
