This is indeed a bug. I have just filed this bug here – https://github.com/jfrog/jfrog-cli/issues/883
The issue is specific to the placeholders feature. JFrog CLI seems to misinterpret the correct definition of –flat, when it is used together with placeholders in the “jfrog rt download” command. I believe this issue will be worked on very soon.
Thanks a lot for sharing this!
