在汇流插件中使用JAXB

我正在开发一个汇流插件,它包含一系列使用JAXB的类。当插件运行时,我得到以下运行时异常:

[INFO] [talledLocalContainer] javax.xml.bind.JAXBException: Provider com.sun.xml.bind.v2.ContextFactory not found
[INFO] [talledLocalContainer]  - with linked exception:
[INFO] [talledLocalContainer] [java.lang.ClassNotFoundException: com.sun.xml.bind.v2.ContextFactory]
