I had this problem recently what I found was that in the run configuration you need to direct the eclipse to the binary. Check if you have the path to the binary and verify the binary is present in the place. it will be something like this

/home/username/catkin_ws/devel/lib/package_name/executable_name

I also recommend you to follow this answer

I found this method much easier to get the parameter value from the server

 double map_resolution;
  // **rosparam list** < use this command to see all the parameters
  if (ros::param::get("/move_base/global_costmap/resolution", map_resolution))
  {
    ROS_INFO("map resolution: %f",map_resolution);
  }
  else
      ROS_INFO("couldn't get map resolution");
