无法运行具有httpclient依赖关系的maven jar

使用maven创建jar文件,当我尝试执行java-jar时,出现以下异常:

Error: A JNI error has occurred, please check your installation and try again
    Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/http/client/methods/HttpUriRequest
        at java.lang.Class.getDeclaredMethods0(Native Method)
        at java.lang.Class.privateGetDeclaredMethods(Class.java:2701)
        at java.lang.Class.privateGetMethodRecursive(Class.java:3048)
        at java.lang.Class.getMethod0(Class.java:3018)
        at java.lang.Class.getMethod(Class.java:1784)

请在这方面帮助我。
