Complied success in ros noetic gazebo 11

[AngryTurtle2]

Complied success in ros noetic and test it in docker-ros-noetic-gazebo-11.10

There are so many warning like this, cause it is ignored by gazebo. So I didn't do anything about it

Warning [parser.cc:833] XML Attribute[version] in element[sdf] not defined in SDF, ignoring.

`There is another question occurs to me. Gazebo always has black scene like the photo.
It happened too often that I can't know when will it success.
I have no idea that what happened. Maybe the reason is my poor computer, or I demo it inside docker, or the VPN I used,or network or......

And My computer is
