wsimport 在解析 WSDL 时遇到问题

Question

我正在尝试通过使用此处https://gpcs.3m.com/Gpcs/ClaimProcessingService?wsdl 的 wsimport 解析 WSDL 文件来生成 java 客户端，但无法正常工作。
我在 Windows 中使用 JDK8。以下是详细信息。我正在使用 JVM 参数来解决这样的问题 WebService Client Generation Error with JDK8

C:\workspace\client\src>wsimport -J-Djavax.xml.accessExternalSchema=all -keep https://gpcs.3m.com/Gpcs/ClaimProcessingService?wsdl

[ERROR] Two declarations cause a collision in the ObjectFactory class.
  line 1899 of https://gpcs.3m.com/Gpcs/ClaimProcessingService?xsd=gpcs_standard_2016_3_0.xsd
[ERROR] (Related to above error) This is the other declaration.

我还在本地下载了 WSDL 文件并通过删除一些引用对其进行了修改，因为错误太多而无法看到。当我这样做时，我能够看到下面显示的错误消息的开头

    [ERROR] A class/interface with the same name "com._3m.gpcs.standard._2016_0.ClaimErrorType" is already in use. Use a class customization to resolve this conflict.
      line 3409 of https://gpcs.3m.com/Gpcs/ClaimProcessingService?xsd=gpcs_standard_2016_0_0.xsd

有人知道为什么这无法生成 java 代码吗？我还尝试使用 Eclipse 创建一个 java 客户端，但这也失败并出现以下错误。提前致谢。

我得到它来生成客户端。 WSDL 包含所有系统版本的版本。在 WSDL URL 中传递版本参数将为您提供特定版本。很明显，我在阅读他们的文档时不知何故错过了这一点。

我尝试传递此处提到的 -B-XautoNameResolution 的 JVM 参数 How to use a class customization to resolve file generating conflicts 但这没有用。我找到了一个在线 WSDL 验证网站，发现它缺少太多 XSD 引用，这些都是可用的系统版本。这让我意识到我只需要下载特定版本的 WSDL。
