How to distribute a java app (jar file with bash launcher) through Homebrew?

[Krasnyanskiy]

I have two files: executable jar file jrsh-2.0.4.jar and jrsh.sh script to run the jar. I want to run it through the Homebrew. What should I do to make it possible?

My run.sh script

#!/usr/bin/env bash
java -jar *.jar $*

I created a tar.gz file and made a formula

brew create 'path/to/my/jrsh-2.0.4.tar.gz'

Then I downloaded it using brew install jrsh. But it doesn't work.

Something like this would work. You could either permit Homebrew to create a new Jar script for you, or simply replace bin.write_jar_script with bin.install_symlink libexec/"run.sh". Should work. Let us know if you hit any further issues.

I got this error

$ brew install jrsh

Here is my jrsh.rb file

class Jrsh < Formula
  desc "A Command Line Interface for JasperReports Server"
  homepage "https://github.com/Krasnyanskiy/jrsh/"
  url "https://github.com/Krasnyanskiy/jrsh/releases/download/v2.0.4/jrsh-2.0.4-jar-with-dependencies.jar"

  def install
    libexec.install "bfg-1.12.3.jar"
    bin.install_symlink libexec/"jrsh.sh"
  end

  test do
    system "#{bin}/jrsh"
  end
end

Make sure your brew is up-to-date with brew update.

[Krasnyanskiy]

After update I got this error

I fixed libexec.install and installed jrsh one more time.

[Krasnyanskiy]

But I still can not run the app

$ jrsh
-bash: jrsh: command not found

[Krasnyanskiy]

Hmmm... I made

brew create 'https://github.com/Krasnyanskiy/jrsh/releases/download/v2.0.4/jrsh-2.0.4.zip'
brew audit --strict jrsh
brew update
brew reinstall jrsh

And now it works fine.

[Krasnyanskiy]

Resolved.

[Krasnyanskiy]

Error: No available formula for jrsh Searching formulae... Searching taps...

[DomT4]

Did you create the new formula in a branch and then brew update? You may need to check the branch out again if so.

[Krasnyanskiy]

Oh, how can I do it?

[DomT4]

Any idea if you created the new formula in a branch or not?

[Krasnyanskiy]

Yes, I guess I changed it.

[Krasnyanskiy]

So, I need to make brew install ... again, right?

[DomT4]

Unless you've uninstalled it, the installation should still be there.

[Krasnyanskiy]

I've cleaned up all brew stuff and tried to reinstall the app. Here is what I got

$ brew install 'https://github.com/Krasnyanskiy/jrsh/releases/download/v2.0.4/jrsh-2.0.4.zip'

[Krasnyanskiy]

Seems I uninstalled it

$ brew uninstall jrsh
Error: No such keg: /usr/local/Cellar/jrsh

[DomT4]

You'll need to re-install it from the formula you created.

[Krasnyanskiy]

How can I do it? Could you tell me please what command should I use?

[Krasnyanskiy]

And I've noticed that I can't find the formula: http://brewformulas.org/search?utf8=%E2%9C%93&search%5Bterm%5D=jrsh&commit=Search

[DomT4]

brewformulas will only list official formulae, not user-generated ones that haven't been merged into the core.

You'll need to check out whichever branch you created the formula in, and then brew install jrsh again. You can see which branches exist by doing cd $(brew --prefix) && git branch.

[Krasnyanskiy]

Ok, now it works. But other people could not install it. I made pull request with my formula jrsh.rb.

[DomT4]

Thanks. Will let the test-bot review the submission, Closing here.

[Krasnyanskiy]

Ok, thanks.
