如何更新 JDK 中使用的 JAXB RI 版本？

Question

当我使用 JDK 8 编译我的 XSD 时，我得到了我期望的输出。

当我用 JDK 7 编译我的 XSD 时，它似乎没有读取我的 binding.xjb 文件。

我很确定这是 jaxb-v2 之间修复的众多缺陷之一

• JDK7 第一版 JAXB RI 2.2.4-1

• JDK8 第一版 JAXB RI 2.2.8

发行说明：JAXB

如果可能的话，谁能帮我解决如何更新 JDK 使用的 JAXB RI 版本？

我正在使用 Maven 构建并使用...的依赖项

  <dependency>
    <groupId>org.jvnet.jaxb2_commons</groupId>
    <artifactId>jaxb2-basics-runtime</artifactId>
    <version>0.6.4</version>
  </dependency>

我使用的插件是...

我可能接近这个错误，也许我需要看看org.jvnet.jaxb2.maven2:maven-jaxb2-plugin

这显示了 JDK 和 JDK 8 运行之间的区别。 在左侧，它似乎忽略了 binding.xjc 文件，因此不知道枚举大小。

我们还可以看到生成的java类有不同的类型。

此外，它在 JDK 8 中生成适配器类，但在 JDK 7 中不生成。

Answer 1

一些建议：

1. args 在两个地方定义。一个在/plugin/executions/execution/configuration/args 下，一个在/plugin/configuration/args 下。您可以在/plugin/configuration/args 中获得它。
2. /plugin/configuration 下有 schemaDirectory 和 bindingDirectory 两个属性。在上面的插件用法中看不到，xsds 和 xjbs 都在资源目录本身吗？
3. 您也可以尝试设置这些参数吗： forceRegenerate=true 和 cleanPackageDirectories=false。

只提一个示例插件定义供参考，您可以修剪不需要的细节。
