Windows generated .bat commands broken for JRuby on RubyGems 3 / Bundler 2

[karlhe]

I'm having a problem or would like to suggest a feature.

My current problem is the bundle command does not work as expected with JRuby on Windows.

Filed an issue against JRuby a while back (jruby/jruby#5632), but I don't think it's a problem on the JRuby side.

C:\jruby-9.2.8.0\bin>bundle
'"C:\jruby-9.2.8.0\bin\ruby.exe"' is not recognized as an internal or external command,
operable program or batch file.

It simply appears as if the .bat files are not generated correctly. The contents of bundler.bat/bundle.bat are:

@ECHO OFF
@"%~dp0ruby.exe" "%~dpn0" %*

For comparison, it looks like this in my JRuby 9.2 folder (which is using older Rubygems/Bundler):

@ECHO OFF
IF NOT "%~f0" == "~f0" GOTO :WinNT
@"C:\jruby-9.2.0.0\bin\jruby.exe" "C:/jruby-9.2.0.0/bin/bundle" %1 %2 %3 %4 %5 %6 %7 %8 %9
GOTO :EOF
:WinNT
@"C:\jruby-9.2.0.0\bin\jruby.exe" "%~dpn0" %*

On the surface jbundle seems to work but then rails.bat, rake.bat, etc are still defined like this:

@ECHO OFF
@"%~dp0ruby.exe" "%~dpn0" %*

So any command other than jbundle install will end up failing anyway.

This issue is related to:

• Network problems
• Installing a library
• Publishing a library
• The command line gem
• Other

Here are my current environment details:

$ gem env version
3.0.4

Bundler: 2.0.4
JRuby 9.2.8.0
Windows Server 2016 Standard

I will abide by the code of conduct.

This seems caused by #2119.

@MSP-Greg Could you have a look at it?

@deivid-rodriguez

See PR #2876. Uses the same logic as Gem.ruby for the exe file name.

Thanks @MSP-Greg!

@karlhe I think you can double check that @MSP-Greg's fix works by manually applying his patch to your rubygems installation (it's very simple), and then reinstalling bundler (gem install bundler).

You can revert to your previous rubygems if you want after you confirm the fix with gem update --system 3.0.4 (or whatever).

Replaced the file at lib\ruby\stdlib\rubygems\installer.rb

bundle.bat and rake.bat both look correct, and seem to work as expected.

Thanks!

@karlhe I released 3.0.6 with #2876 . Can you confirm to resolve this issue?

[karlhe]

It still seems to be the same behavior, I don't think the PR actually made it into 3.0.6?

rubygems/lib/rubygems/installer.rb

Line 802 in 9c142f5

@"%~dp0ruby.exe" "%~dpn0" %*

Still looks like the old one

Ah, Sorry. I missed this at 3.0.5 and 3.0.6, I will release with 3.0.7.
