我将一个项目从 迁移Java 8到Java 11，在生成代码时遇到了一些XSD麻烦cxf-xjc-plugin.

即使我确实升级cxf-xjc-plugin到版本3.3.0，在构建项目时仍然会出现异常

我的pom.xml

希望这可以帮助其他面临同样问题的人，

我根据这个stackoverflow answer解决了这个问题，所以我最终添加了 JAXB 依赖项，如下所示：

...
<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.2.8</version>
</dependency>
<dependency>
    <groupId>com.sun.xml.bind</groupId>
    <artifactId>jaxb-core</artifactId>
    <version>2.2.8</version>
</dependency>
<dependency>
    <groupId>com.sun.xml.bind</groupId>
    <artifactId>jaxb-impl</artifactId>
    <version>2.2.8</version>
</dependency>
...

我的项目构建通过，但在运行时我收到一些警告：

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by com.sun.xml.bind.v2.runtime.reflect.opt.Injector (file:/home/tra/.m2/repository/com/sun/xml/bind/jaxb-impl/2.3.0/jaxb-impl-2.3.0.jar) to method java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int)

WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

我在这里读到这个问题将成为 JAXB 未来版本的解决方案
