我有一个带有多个模块的Apache Maven项目。一些模块包含其他模块使用的实用程序类。某些模块是独立的Java应用程序，它们在其他模块中使用类。
每个应用程序都在运行时通过XML进行配置。我为每个应用程序定义了一个架构，该架构也通过JAXB / XJC转换为Java类。这就是我将配置信息传输到Java应用程序中的方式。
其中一个实用程序还具有用于配置的XML模式。我需要能够提供从该架构到其他应用程序配置架构的定义。这将允许我将实用程序的配置元素嵌入到应用程序配置中。
当我在maven-jaxb2-plugin网站上找到有关<catalog>和<episode>的信息时，我一直在试图找出最好的方法。我阅读了这些部分以及相关的代码示例，并尝试复制自己的代码中所做的事情，但不起作用。
对于下面冗长的代码和异常示例，我事先表示歉意。
这是我的设置的缩写示例：

当我尝试构建时，会得到冗长的异常跟踪：

我的任何模式都不以任何方式“提供”。它们没有通常意义上的URL。看起来该过程正在尝试在URL（example.org）上找到引用的实用程序架构，该URL不存在。从我在maven-jaxb2-plugin站点上阅读的印象中，所描述的技术可以用于“伪造”或“重写” URL。我错了吗？如何解决通过HTTP提供模式的问题？我没有使用Web服务器，也不是一个选择。我使用插件的方式有问题吗？
更新：美国东部夏令时间2018年8月9日星期四07:45:55
经过更多的网络搜索和反复试验后，我终于能够使它起作用。我发现信息表明XML模式的名称空间不需要可以是URL，但可以是或多或少的任何东西。
因此，我将模式名称空间更改为仅具有有意义的纯文本字符串。我终于能弄清的另一件事是如何在目录文件中正确指定Maven工件。一旦确定了可行的方法，便可以构建。
实用程序架构（camel-config.xsd）：
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="camel_config" xmlns:camel="camel_config"
elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:complexType name="CamelConfig">
...
</xs:complexType>
...
</xs:schema>
取决于上面的实用程序架构的应用程序架构：
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="injector"
xmlns:inj="injector" xmlns:camel="camel_config"
elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:import namespace="camel_config" />
...
<xs:complexType name="WireCaptureConfig">
<xs:sequence>
...
<xs:element name="camel-config" type="camel:CamelConfig" />
...
</xs:sequence>
</xs:complexType>
...
</xs:schema>
更正的目录文件：
PUBLIC "camel_config" "maven:{utility module group ID}:{utility module artifact ID}:jar::{utility module version}!/config/camel-config.xsd"
config目录位于src/main/resources下。我不明白如何在Maven或插件“ knew”中查找并找到它。
