jrubyexec task yaml load error with 9.0.0.0.pre2 #113

hleeldc · 2015-05-05T16:08:37Z

I have a directory with 2 files:

build.gradle
test.rb

Here's the content of build.gradle:

plugins {
    id "com.github.jruby-gradle.base" version "0.1.15"
}

jruby.execVersion '9.0.0.0.pre2'

import com.github.jrubygradle.JRubyExec

task run(type: JRubyExec) {
    script 'test.rb'
}

test.rb contains just one line:

require 'yaml'

Executing "gradle run" returns the following error:

:run
uri:classloader:/META-INF/jruby.home/lib/ruby/stdlib/rubygems/core_ext/kernel_require.rb:1:in `require':
It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your ruby.
LoadError: load error: psych -- java.lang.NullPointerException: null
...

It works if I remove the jruby.execVersion line, but then it falls back to jruby-complete 1.7.19.

Any idea?

The text was updated successfully, but these errors were encountered:

This definitely looks like it might be an issue with the jruby-complete archive for 9000pre2. If you set the Java flag debug.fullTrace=false that might show you more information (unless @headius meant a different flag)

hleeldc · 2015-05-05T18:47:52Z

I'm not sure if the problem is in the jruby-complete archive because the following works fine.

java -cp ~/.gradle/caches/modules-2/files-2.1/org.jruby/jruby-complete/9.0.0.0.pre2/5c21f8a488eda22f4dad9e92431a6754fb0acd77/jruby-complete-9.0.0.0.pre2.jar org.jruby.Main test.rb

BTW, gradle run -Ddebug.fullTrace=false didn't output more information.

enebo · 2015-05-05T20:12:10Z

@hleeldc @rtyler You can -Djruby.debug.fullTrace=true. I tend to use -Djruby.backtrace.style=raw for internal Java backtrace errors, but I think the former nests both Ruby and Java trace elements together.

rtyler · 2015-05-06T14:52:47Z

@enebo @headius I've taken @hleeldc's example and found that I only get errors with pre2, but I'm not able to get the stacktraces from it.

Here's an example run with pre1:

I've placed the repro case in this gist which can be executed with Gradle 2.1+

basically it sets up the jars in the same manner as it would pack it inside a jar and uses the usual loading semantic for loading jars with jruby. and with this the jrubyExec task does not need interfer with those embedded jars coming with jruby itself like bouncycastle jars, jline jar or snakeyaml jar. fixes #123 and #113

ysb33r · 2015-07-06T20:45:12Z

Has anyone tried this yet with 9.0.0.0.rc-1 ?

mkristian · 2015-07-06T21:55:35Z

actually this is not a problem with jrubyExec anymore after #123 got merged since all jars are loaded via require including snakeyaml.jar from psych.

removing this line keeps those require_jar working: 5d59833#diff-b881b1c59e2fb0993fddd8f8a361cc0cL115

jrubyExec should set JARS_HOME and use the jar as jruby does #123
