brew doctor fails with java cask error

[offbyone]

Bug report

Please note we will close your issue without comment if you delete, do not read or do not fill out the issue checklist below and provide ALL the requested information. If you repeatedly fail to use the issue template, we will block you from ever submitting issues to Homebrew again.

• [X ] ran brew update and can still reproduce the problem?
• [X ] ran brew doctor, fixed all issues and can still reproduce the problem?
• [X ] ran brew config and brew doctor and included their output with your issue?

What you were trying to do (and why)

Run brew bundle --global to sync my homebrew

What happened (include command output)

Most of it works fine, but at the end of the run I get this:

Error: Cask 'java' is unreadable: undefined method `undent' for #<String:0x00007fed782eaa50>
Homebrew Bundle complete! 145 Brewfile dependencies now installed.

That in and of itself would be weird, since I don't have a cask reference to `java` in that brewfile, but it's weirder:

Command output

$ brew doctor --verbose
Error: Cask 'java' is unreadable: undefined method `undent' for #

## What you expected to happen brew doctor should have worked :) ## Step-by-step reproduction instructions (by running `brew` commands) I can repro it by running `brew doctor`. Odds are good that you won't be able to, so I would love to know how to get a better debug output so I can send you a stack trace, or delete the random broken think that I clearly have somewhere on this computer. ## Output of `brew config` and `brew doctor` commands

For what it's worth, I've tried to find a java cask too, or anything with undent called in my Homebrew cellar:

Can you see if brew update-reset fixes this for you?

It did not:

How about:

find -name java.rb /usr/local/Homebrew/Library/Taps

[offbyone]

Comes up empty (find -L /usr/local/Homebrew/Library/Taps -name java.rb specifically, to follow any symlinks if present)

If I expand to a java wildcard, I get this, but I think they're not related:

$ find -L /usr/local/Homebrew/Library/Taps -name 'java*.rb'
/usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask-versions/Casks/java-beta.rb
/usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask-versions/Casks/java6.rb
/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/javacc.rb
/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/javarepl.rb

[reitermarkus]

Probably caused by the saved cask file in $(brew --caskroom)/java/.metadata.

[offbyone]

Holy carp, that's it!

I ... I have no idea whatsoever how I would debug this in practice. I've literally never seen that path turn up in any log anywhere.

[legoritma]

@offbyone Did you solve the problem? I have exactly same issue and "$(brew --caskroom)/java/.metadata." exist

Update: I deleted "$(brew --caskroom)/java/" it's working now

[offbyone]

Yep. Removing that file cleaned up the situation. I haven't closed this in case the homebrew folks need anything from me to investigate (and I assume they consider this a bug)

[MikeMcQuaid]

Assuming this is a known issue on Cask side so closing, thanks all!
