Yes, you most likely have to.
In general I’d suggest you to try the CLI locally on your Mac/Linux (https://www.bitrise.io/cli / How to experiment with Bitrise configs locally, on your Mac/Linux), that way you can check what’s moved automatically into the $BITRISE_DEPLOY_DIR and what isn’t.
The build log in general should also include the files which are moved into the deploy dir; e.g. the Gradle Runner prints every file at the bottom of it’s “step log box” which are moved into the deploy dir.
If you’d have any questions just let us know!
