Question Subject

Turtle build command not building any files when running on CircleCI.

Question Description

When trying to run the turtle build:android command on CircleCI, it doesn't produce any files, despite not throwing any errors. I also already SSH'd into my container and tried to do the steps manually, and this did work.

Now, I'm completely lost on what I can do to fix this, especially because I don't receive any information regarding the build. There's no error thrown at all and all steps run before, are executed right. Including the turtle setup. As you can see in the screenshot, the build time is also 0s
