spark jars do not contain commons-jxpath jar, cause ClassNotFound exception

When submit a spark application using XPathExpressionEngine, a ClassNotFound exception will be thrown, even though I shade then class of commons-jxpath:commons-jxpath into my jar.

The main class of my jar is as follows:

object StaticTestMain {
   def main(args: Array[String]): Unit = {

       println(s"yanzhi class loader info ${getClass.getClassLoader}")
       val engine = new XPathExpressionEngine() // exception happends in this line

        // some other codes.
   }
}

And configuration of shade plugin as the attached picture file "shade_in_pom.jpg"

The exception stack trace is in the attached picture file "exception_stack_trace.jpg".
