Bash Completions Kills Shell (Mac/Homebrew)

[mrg]

I'm not sure if the Homebrew packaging is maintained here (if not, maybe add a comment to the README), but after installing via Homebrew and adding source /usr/local/bin/mvnd-bash-completion.bash to my ~/.bash_login, all future shells were killed with:

Last login: Tue Dec 20 06:51:54 on ttys009
-bash: /usr/local/Cellar/mvnd/0.8.2/libexec/bin/mvnd-bash-completion.bash: Permission denied
-bash: exec: /usr/local/Cellar/mvnd/0.8.2/libexec/bin/mvnd-bash-completion.bash: cannot execute: Undefined error: 0

Fortunately, I had other shells open and it was easy to undo. The contents of source /usr/local/bin/mvnd-bash-completion.bash are:

#!/bin/bash
JAVA_HOME="${JAVA_HOME:-/usr/local/opt/openjdk/libexec/openjdk.jdk/Contents/Home}" exec "/usr/local/Cellar/mvnd/0.8.2/libexec/bin/mvnd-bash-completion.bash"  "$@"

If I replaced /usr/local/bin/mvnd-bash-completion.bash with /usr/local/Cellar/mvnd/0.8.2/libexec/bin/mvnd-bash-completion.bash, the sourcing works, but isn't robust if the version number changes.

The home-brew package sources are at https://github.com/mvndaemon/homebrew-mvnd/tree/master.
I can't find where a file such as the one you have would come from, but I have the same locally, so I suppose it's generated by home-brew during the installation process. So I don't think the hardcoded version is a problem, as it will be updated by home-brew. I think the problem is that the /usr/local/Cellar/mvnd/0.8.2/libexec/bin/mvnd-bash-completion.bash has no executable flag.
