Polarion二次开发的插件中，对Servlet新增、修改或删除时，发布到应用需要删除.config文件才能使修改生效，每次需要手动执行，不如加到restart启动脚本中。只需修改start函数即可。

代码如下：

vi /opt/polarion/bin/polarion.init

start() {
        check_start
        echo;
        echo "Starting Polarion service..."
        echo "Please wait for background operation to finish! For more information see:";
        echo "tail -100f $logFile OR $0 log";
        echo;
        echo 'Launching the Polarion Server. This can take some time; please be patient...'
        echo "Delete .config directory..."
        rm -rf /opt/polarion/data/workspace/.config
        echo "Delete .config directory done"

        if check_systemd && check_polarionUnitFile; then
                systemctl start polarion
        else
                startPolarion
        fi

        if check_pid_f
        then
                echo -e "\nRunning Polarion service..."
#               (exec -a "Log waiting" tail -100f $logFile ) &
        fi
}
