ruby-runtime 0.11 completely breaks RVM #86

Closed evanphx closed 11 years ago

evanphx commented 11 years ago

Indicating a ruby to build with via the RVM plugin results in:

Downgrading to 0.10 fixes the issue.

Please let me know the version of Jenkins.

I confirmed this on Jenkins 1.517 + ruby-runtime 0.11 + rvm plugin 0.4. The cause of this problem is old gem dependency (jenkins-plugin-runtime 0.1.17) of rvm plugin 0.4.

Because the latest master of rvm plugin is using jenkins-plugin-runtime 0.2.3 (latest) at jenkinsci/rvm-plugin@e54486ebfa0513c5b6ca74764a8cbcd7c98dbb61, install rvm plugin from master should solve this problem. Though, there is another incompatibility issue (class hierarchy changes) between jenkins-plugin-runtime 0.1.17 and 0.2.3. Just upgrading rvm plugin may lose job configurations :(

evanphx commented 11 years ago

It was Jenkins 1.504. I thought that upgrading the RVM plugin might solve the issue, but 0.4 is the latest released version, leaving me stuck.

yyuu commented 11 years ago

Yep, rvm plugin 0.4 is the latest release version. The latest development version can only be accessed via github repo.

Tested with small script.

#!/usr/bin/env ruby
require "java"
puts(RUBY_DESCRIPTION)
java.lang.System.out.write("hello, world\n")

JRuby 1.6 translates call of write(String) on java.io.PrintStream as call of java.io.PrintStream#print(String).

hello, world

JRuby 1.7 doesn't treat so.

Confirmed that setting java_alias on java.io.PrintStream will solve problem on ruby-runtime 0.11+.

require "java"
java_import java.io.PrintStream
class PrintStream
  java_alias(:write, :print, [java.lang.String])
end
