我正在尝试从用于FHIR的xsd生成java代码。
我从这里下载了代码生成模式，然后运行：
xjc patient.xsd
但我有以下例外：
parsing a schema...
[ERROR] src-resolve: Cannot resolve the name 'Account' to a(n) 'type definition' component.
line 332 of file:/Users/gerard/Downloads/fhir-codegen-xsd/fhir-base.xsd
[ERROR] src-resolve: Cannot resolve the name 'DetectedIssue' to a(n) 'type definition' component.
line 354 of file:/Users/gerard/Downloads/fhir-codegen-xsd/fhir-base.xsd
[ERROR] src-resolve: Cannot resolve the name 'ImplementationGuide' to a(n) 'type definition' component.

[ERROR] src-resolve: Cannot resolve the name 'QuestionnaireResponse' to a(n) 'type definition' component.
line 409 of file:/Users/gerard/Downloads/fhir-codegen-xsd/fhir-base.xsd
[ERROR] src-resolve: Cannot resolve the name 'Parameters' to a(n) 'type definition' component.

[ERROR] src-resolve: Cannot resolve the name 'MeasuredQuantity' to a(n) 'type definition' component.
line 225 of file:/Users/gerard/Downloads/fhir-codegen-xsd/questionnaireanswers.xsd
我已经将所有xsd导入eclipse，但在fhir-base.xsd中看到了相同的错误。不确定如何解决它，因为例如account.xsd在同一目录中。
我也遇到了同样的问题。我尝试了fhir网站上提供的档案中的三种资源：
fhir-base.xsd
fhir-all.xsd
fhir-single.xsd
针对fhir-base.xsd…，每个错误似乎都采用相同的形式（其中73个条目）
[ERROR] Property "Lang" is already defined. Use <jaxb:property> to resolve this conflict.
line 323 of file:/E:/fhir-spec/resources/fhir-all-xsd/fhir-xhtml.xsd
[ERROR] The following location is relevant to the above error
line 324 of file:/E:/fhir-spec/resources/fhir-all-xsd/fhir-xhtml.xsd
只是在尝试一些暴力战术。。我在fhir-xhtml.xsd:中发现并评论了几行
Lines 323, 324
<xs:attribute name="lang" type="LanguageCode"/>
<xs:attribute ref="xml:lang"/>
Line 1351
<xs:attribute name="lang" type="LanguageCode"/>
在这之后，我能够成功地生成代码。
mkdir gen
xjc -d gen fhir-base.xsd
我找不到任何"官方"（如github等）来提交问题。我不完全确定xhtml内容的意图，但我想知道这里可能发生的是fhir数据类型"LanguageCode"和语言代码的html规范之间的冲突吗？
祝你好运！
有一个单独的模式叫做fhir-all.xsd。当所有内容都在一个文件中时，代码生成器往往会更快乐，所以我们发布这个模式就是为了这个目的。
