chunjun_client pom 增加：

chunjun_core pom 修改

<target>
    <copy file="${basedir}/target/${project.artifactId}-${project.version}.jar"
         tofile="${basedir}/target/${project.artifactId}.jar"/>
    <copy todir="${basedir}/../core/"
         file="${basedir}/target/${project.artifactId}.jar"/>
    <delete>
       <fileset dir="${basedir}/../core"
              includes="${project.artifactId}-*.jar"
              excludes="${project.artifactId}.jar"/>
    </delete>
</target>
