edit

HI all! I'm trying create a moveit package for my own robot following the tutorial Create_a_MoveIt_Pkg_for_an_Industrial_Robot. When I finished the second part Update Configuration Files I tested the configuation.However, there was something wrong. When I start the planning _and_execution.launch, there was something output like this:

OSError: [Errno 13] Permission denied: '/home/shantengfei/catkin_ws/src/jaka_ur_moveit_config/default_warehouse_mongo_db'

I checked the ros package jaka_ur_moveit_config and there are just two folders: launch and config. In the launch folder, there is a default_warehouse_db.launch file which was generated when I set up the moveit assistant:

<launch>

  <arg name="reset" default="false"/>
  <!-- If not specified, we'll use a default database location -->
  <arg name="moveit_warehouse_database_path" default="$(find jaka_ur_moveit_config)/default_warehouse_mongo_db" />

  <!-- Launch the warehouse with the configured database location -->
  <include file="$(find jaka_ur_moveit_config)/launch/warehouse.launch">
    <arg name="moveit_warehouse_database_path" value="$(arg moveit_warehouse_database_path)" />
  </include>



 <!-- If we want to reset the database, run this node -->
  <node if="$(arg reset)" name="$(anon moveit_default_db_reset)" type="moveit_init_demo_warehouse" pkg="moveit_ros_warehouse" respawn="false" output="screen" />
</launch>

and here is the moveit_planning_execution.launch

<launch>

  <arg name="sim" default="true" />
  <arg name="robot_ip" unless="$(arg sim)" />

  <include file="$(find jaka_ur_moveit_config)/launch/planning_context.launch" >
    <arg name="load_robot_description" value="true" />
  </include>

  <group if="$(arg sim)">
    <include file="$(find industrial_robot_simulator)/launch/robot_interface_simulator.launch" />
  </group>

  <group unless="$(arg sim)">
    <include file="$(find [robot_interface_pkg])/launch/robot_interface.launch" >
      <arg name="robot_ip" value="$(arg robot_ip)"/>
    </include>
  </group>

  <node name="robot_state_publisher" pkg="robot_state_publisher" type="robot_state_publisher" />

  <include file="$(find jaka_ur_moveit_config)/launch/move_group.launch">
    <arg name="publish_monitored_planning_scene" value="true" />
  </include>

  <include file="$(find jaka_ur_moveit_config)/launch/moveit_rviz.launch">
    <arg name="config" value="true"/>
  </include>

  <include file="$(find jaka_ur_moveit_config)/launch/default_warehouse_db.launch" />

</launch>

As can be seen, <arg name="moveit_warehouse_database_path" default="$(find jaka_ur_moveit_config)/default_warehouse_mongo_db" />. But I didn't find the default_warehouse_mongo_db.Could someone please give a method to solve the problem? Thanks.
