Rake bootstrap fails on with JRuby 9.1.13.0

[jakelandis]

To reproduce:

git clone https://github.com/elastic/logstash.git
(ensure clean environment)
rvm implode
\curl -sSL https://get.rvm.io | bash -s stable
rvm install jruby-9.1.13.0
(new shell)
cd logstash
rvm use jruby-9.1.13.0
rake bootstrap

results in

 rake bootstrap
mkdir -p vendor
mkdir vendor/_

Workarounds:

• Use JRuby 9.1.12.0 to bootstrap (.13 will still be used when running)
• (assuming rake is installed elsewhere):

gem uninstall -i  ~/.rvm/gems/jruby-9.1.13.0@global rake

[jordansissel]

The workaround (remove rake) fails on Windows JRuby:

PS C:\Users\jls\IdeaProjects\logstash> gem uninstall rake
ERROR:  While executing gem ... (Gem::InstallError)
    gem "rake" cannot be uninstalled because it is a default gem

[jordansissel]

Attempting to use rake 12.1.0 directly also fails:

PS C:\Users\jls\IdeaProjects\logstash> jruby C:\jruby-9.1.13.0\lib\ruby\gems\shared\gems\rake-12.1.0\exe\rake --version 
rake, version 12.1.0

PS C:\Users\jls\IdeaProjects\logstash> jruby C:\jruby-9.1.13.0\lib\ruby\gems\shared\gems\rake-12.1.0\exe\rake bootstrap Installing minitar 0.5.4 because the build process needs it.
[bootstrap] Fetching and installing gem: minitar (0.5.4)
rake aborted!
Gem::UnsatisfiableDependencyError: Unable to resolve dependency: user requested 'rake (= 12.1.0)'

[jordansissel]

Workaround confirmed - Downgrade system jruby to 9.1.12.0

PS C:\Users\jls\IdeaProjects\logstash> jruby -S rake bootstrap

let us call it a day, bootstrap seems fine these days using JRuby 9.2
