ROS2 Build Action Tutorial "Colcon build Failed"

edit

I'm currently following ROS2 Build Action tutorial: link text, and I'm stuck with the colcon build, the tutorial asks to add some lines to my CMakeLists and package files before building the package (The lines are encased with comments). Yet I'm getting errors that suggests I should remove some lines. I'll provide the errors and the files.

Error 1:
