Failed to download sources, not a gitlink tree

[Chris Hessing]

Hello all,


I'm attempting to create my first flatpak file, and have run headlong in 
to an error that searching the net hasn't turned up an answer for.  
Specifically, when I attempt to run flatpak-builder with the following 
command line :


flatpak-builder --ccache --repo=repo --subject="Test Build `date`" app 
org.open1x.Rollin.json


It indicates that it is fetching the git repo, then errors out with the 
following error message :


Failed to download sources: module Rollin: Not a gitlink tree: QtTestRunner


QtTestRunner is another git repo that I created to store some extra code 
used to run unit tests on part of the app. Originally, it was included 
in the repo as a submodule.   When I got this error, I originally 
thought it was because that repo needed to be linked as a sublink.   So, 
I attempted to remove the submodule, and convert it to a sublink.   That 
didn't resolve the issue, so I finally tried to purge the sublink, and 
just put the code directly in my repo to try to get things working. 
Unfortunately, it seems that I was unsuccessful in removing the 
submodule or sublink, because I continue to get this error. (Either 
that, or this error is referring to something else that I don't quite 
understand, yet.)


Is there someplace that someone can suggest that I can read up on what 
this error means, and how to fix it?   (Or, if it is easier, give me the 
solution to the problem, and I can study from there.)


Ideally, I'd like to be able to link to the other git tree for the 
QtTestRunner component, but at this point I am open to just keeping the 
source for that in-tree if that is easier.



FWIW - flatpak-builder --version returns :


flatpak-builder 1.0.1


And, my .json file looks like this :


{
     "id": "org.open1x.Rollin",
     "branch": "master",
     "runtime": "org.kde.Platform",
     "runtime-version": "5.9",
     "sdk": "org.kde.Sdk",
     "command": "Rollin",
     "finish-args": ["--socket=x11", "--socket=wayland", 
"--filesystem=host" ],
     "modules": [
         {
             "name": "Rollin",
             "buildsystem": "simple",
             "build-commands": [
                 "qmake",
         "make -j2"
             ],
             "sources": [
                 {
                     "type": "git",
                     "url": "https://github.com/fbatogo/Rollin.git"
                 }
             ]
         }
     ]
}




My goal with that JSON file is to get something very basic working, and 
then start to expand on it with everything else that I want to add.    
So, I am also open to any critique about the JSON file as well.


Thanks!
