I see. Yes that is annoying many people have been hitting that bug. It is already fixed, and from your comment it seems you probably already know that and found the issue with its workaround.
The workaround has worked for other people, so maybe double check again if you copied and renamed everything right.
The 'stuck' problem with the command prompt is really to be expected. This is because 'run-app' is a bit special in that the command doesn't typically terminate since the server is meant to keep running.
The command is stuck... because its essentially waiting for the command to finish / terminate.
Maybe there's something we can do about this, maybe make run-app a special case in the command prompt and somehow execute it asynchronously. I'll need to think about it a bit.
Thanks for elaborating on the details.
Edit: adding a link to issue with workaround for this error: "Error opening zip file or JAR manifest missing : null"
I realize you probably already found it, but other people may end up here via google search.
