我想用 xjc（版本 2.3.0-b170531.0717）从 XSD 生成 Java 类

不幸的是，XSD 导入了另一个在带有 Windows 路径分隔符（反斜杠\）的相对路径中给出的 XSD，根据 RFC-2396 中的xsi:schemaLocation 反斜杠不允许将其声明为排除字符？

运行时xjc，架构编译得很好。但是我想用命令行参数指定一些绑定，-b bindings.xjb然后反斜杠成为一个问题，导致模式解析失败。

我该如何解决这个问题？我曾尝试使用目录来解析路径，但在使用目录之前它似乎失败了。

最小的工作示例

a.xsd

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:b="b.xsd"
        xmlns:xsd="http://www.w3.org/2001/XMLSchema"
        elementFormDefault="qualified">
    <xsd:import namespace="b.xsd" schemaLocation=".\b.xsd"/>
</xsd:schema>

b.xsd

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    targetNamespace="b.xsd"
    elementFormDefault="qualified"/>

c.xjb

<?xml version="1.0" encoding="UTF-8"?>
<jaxb:bindings
    xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
    xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
    xmlns:xs="http://www.w3.org/2000/10/XMLSchema-instance"
    xs:schemaLocation="http://java.sun.com/xml/ns/jaxb http://java.sun.com/xml/ns/jaxb/bindingschema_2_0.xsd"
    jaxb:version="2.0" />

控制台输出

> xjc a.xsd
parsing a schema...
compiling a schema...

> xjc a.xsd -b c.xjb
parsing a schema...
[ERROR] Unable to parse ".\b.xsd" : File name is not an URI. Illegal character in path at index 1: .\b.xsd
  line 3 of a.xsd

Failed to parse a schema.

编辑：随着xjc -verbose我得到以下 StackTrace，说明 Java 的URI类符合标准并因此拒绝反斜杠是一个问题。
