[autoware.auto] build code from Atom does not work in ADE

edit

In the docs it says Atom should be able to build the project:

https://autowarefoundation.gitlab.io/...

These are the terminal commands I am using (they include the workspace preparation steps for code navigation); I just copied and pasted from the docs:

me@host:~/adehome/AutowareAuto 1$ ade start
me@host:~/adehome/AutowareAuto 1$ ade enter                              
me@ade:~$ cd ~/AutowareAuto
me@ade:~/AutowareAuto (master u=)$ rm -rf .clang_complete build install log
me@ade:~/AutowareAuto (master u=)$ export CC=$PWD/tools/clang_complete/cc
me@ade:~/AutowareAuto (master u=)$ export CXX=$PWD/tools/clang_complete/g++
me@ade:~/AutowareAuto (master u=)$ ctags -R .
me@ade:~/AutowareAuto (master u=)$ colcon build --cmake-args '-DCMAKE_BUILD_TYPE=Debug'
me@ade:~/AutowareAuto (master u=)$ atom

In Atom, I go to File > Add Project Folder... and I add the top level AutowareAuto folder. Then I add something like localization_nodes as a project folder, select it, and hit F9 and this is what I see:

Does anyone know what might be wrong?
