我正在尝试使用JiBX Code Gen工具为[OTA2003B]（http://www.opentravel.org/Specifications/SchemaIndex.aspx?FolderName=2003B）提供的OTA模式生成代码（使用自定义）。以下是为实现此目的而编写的代码。

当我尝试从配置的模式生成代码时，生成的代码没有绑定文件，我收到以下错误：

我可以看到两个模式中都指定了上面显示的错误中引用的元素，例如 InventoryStatusType 可用。由于这个问题正在发生。但是我已经指定了 prefer-inline =“true”，并且在我的每个模式代码中生成了不同的包 custom1.xml ，这意味着对于这两个模式， InventoryStatusType 的完全限定名称（假设这将被创建为内部类）将是不同的，这不应该创建像我遇到的那样重复错误。
1）导致问题的是什么以及 generate-all =“false”如何能够避免此问题？
2）如何在不使用 generate-all =“false”的情况下解决重复名称错误？
注意：当使用generate-all =“false”生成绑定文件时，但在编译绑定时，我面临以下错误：

在发布问题后，我在网上查看了OTA模式（http://www.opentravel.org/Specifications/SchemaIndex.aspx?FolderName=2003B）我试图从中生成代码，我发现上面链接中可用的那个和我所拥有的那个是不同的。所以我认为架构的扁平化版本 我可能会导致这个问题。所以我下载了模式的在线版本，它的结构正确，包含了 常见的模式，即
<xs:include schemaLocation="OTA_VehicleCommonTypes.xsd"/>
<xs:include schemaLocation="OTA_SimpleTypes.xsd"/>
<xs:include schemaLocation="OTA_CommonTypes.xsd"/>
<xs:include schemaLocation="OTA_CommonPrefs.xsd"/>
<xs:include schemaLocation="OTA_AirCommonTypes.xsd"/>
注意：我没有在我的代码中使用OTA_AirCommonTypes.xsd，因为在此架构定义中出现了与架构元素相关的一些错误。
所以我认为现在提到的模块化生成技术（http://jibx.sourceforge.net/fromschema/example-modular.html）可以提供帮助。 我继续进行相同的操作，以下是我编写的代码：
jibx-maven-plugin配置

首先，我应用了生成代码的 custom_a.xml 并运行了jibx：bind目标，该目标成功编译了绑定（base-binding.xml）。 然后我评论了应用custom_a.xml的配置部分，并启用了配置部分以应用 custom_b.xml 它成功生成了代码但运行绑定编译器产生了以下错误：

答案 0 :(得分：1)
Jignesh，
当您使用平面模式（前缀为FS_的模式）时，最好不要一次编译多个模式，因为所有包含的模式将在每个顶级模式中重复。
由于您无论如何都需要不同的包名称，请将其拆分为两个项目，其中一个包括：
<includeSchemas>
<includeSchema>FS_OTA_VehAvailRateRQ.xsd</includeSchema>
</includeSchemas>
和另一个包含此内容：
<includeSchemas>
<includeSchema>FS_OTA_VehAvailRateRS.xsd</includeSchema>
</includeSchemas>
这是在不使用generate-all =“false”的情况下解决重复名称错误的最简单方法。
