JAXB+；JAK java.lang.ClassCastException

我阅读了关于pom.xml文件（）中的一段代码的页面。这段代码实际上是在pom.xml文件中注释的，所以我取消了注释，以便添加我自己的模式进行编译。之后，我运行命令mvn-e clean install，得到以下错误：

ivansek ~/Sites/Xlab/KMLTest/javaapiforkml-read-only $ mvn -e clean install

有什么建议吗？

看起来像是JAXB版本的地狱问题，与线程中提到的问题相同：JAK插件依赖于JAXB 2.2，但您的JDK有另一个版本

尝试安装JAXB2.2（使用认可的机制）。请参阅。

可以在此处找到解决此版本问题的好方法：
