Problem with RSpec+Maven+jruby-complete.jar

Ruby JRuby
1

Hi,

I’m trying to run RSpec from Maven through the jruby-rake-plugin. I’m
getting an error where the plugin is looking for bin/spec:

[INFO] Error opening script file: /Users/mario/Desktop/
abstra.cc/projects/BMClient/file:/Users/mario/.m2/repository/org/jruby/jruby-complete/1.4.0/jruby-complete-1.4.0.jar!/META-INF/jruby.home/lib/ruby/gems/1.8/gems/rspec-1.2.9/bin/spec(No
such file or directory)
[WARNING] rake aborted!
[WARNING] Command

“src/test/ruby/spec/core/backend_spec.rb”
“src/test/ruby/spec/core/model_spec.rb” --format specdoc failed

and of course, bin/spec doesn’t exist in jruby-complete.jar.

A workaround for the moment is to have a full instalation if JRuby and
do a
-Djruby.home when calling mvn, but that’s a stopgap measure. Any ideas?
Should I report this as a bug?

Here’s the relevant part of my pom.xml. jruby.version is set to 1.4.0:

src/main/scala src/test/scala src/main/ruby org.jruby.plugins jruby-rake-plugin ${jruby.version} install-gems process-resources install-gems ${gem.options} ${required.gems} ${testing.required.gems} clobber clean rake ${basedir} clobber runtests test rake ${basedir} spec rdoc verify rake ${basedir} rdoc

-Mario.

Mario, where or when did you get that jar? I just downloaded the version
in
repo2.maven.org and it contains the spec file:

david@david-mirai ~/dev/jruby$ jar -tf

/home/david/Downloads/jruby-complete-1.4.0.jar
META-INF/jruby.home/lib/ruby/gems/1.8/gems/rspec-1.2.9/bin/spec
META-INF/jruby.home/lib/ruby/gems/1.8/gems/rspec-1.2.9/bin/spec

It’s also included in the development version:

david@david-mirai ~/dev/jruby$ jar -tf lib/jruby-complete.jar

META-INF/jruby.home/lib/ruby/gems/1.8/gems/rspec-1.2.9/bin/spec
META-INF/jruby.home/lib/ruby/gems/1.8/gems/rspec-1.2.9/bin/spec

There’s also a maven-rspec-plugin that I’ve used in the past.

Works okay, but not awesome.

I’ve added some hacks so you can run specs outside of maven, but still
get your maven-managed classpath also. After the first run involving
maven, you’re left with a target/spec-runner.rb you can use to execute
individual specs. (If I recall).

If the goal is writing / running tests – I have been using JtestR
successfully for quite some time, in a large maven 2 project. It has
maven plugin and comes with many test tools bundled in (for example,
Mocha, which I use for mocking.)

Looking in my jruby-complete.jar I see that it does indeed include
bin/spec.
However, the problem looks to be the way the jruby-rake-plugin sets up
the
load path. Look at the first error line:

[INFO] Error opening script file: /Users/mario/Desktop/
abstra.cc/projects/BMClient/file:/Users/mario/.m2/repository/org/jruby/jruby-complete/1.4.0/jruby-complete-1.4.0.jar!/META-INF/jruby.home/lib/ruby/gems/1.8/gems/rspec-1.2.9/bin/spec(No
such file or directory)

For some reason it’s prepending either the CWD or the directory where
the
pom.xml file resides to the file: URL.

try to remove in your pom.xml

${basedir}

that could cause the problem.

I remember that I spent quite some time to rectify the behavior of the
launchdirectory in jruby-rake-plugin (which I cloned for the
rails-maven-plugin) to work probably in various maven scenarios
(reactor, etc)

Feel free to file bugs and/or patches for the jruby-rake-plugin. I
wrote it quite a while ago but don’t use it heavily, and thus I don’t
know whether it works well for others and don’t promote it very much
(hence the lack of documentation).

@Nick

I submitted some patches. I would like to add following more to reach
something we can use for datamapper but first want to hear some
feedback:

  • allow to configure the GEM_HOME,GEM_PATH via properties in the
    settings.xml and use it for the forked jruby
  • add my rspec goal to the rake-plugin
  • allow to use nailgun for the forked

I guess I have more ideas but only limited time.

with regards
Kristian

I have the same problem running Test::Unit via jruby-rake-plugin.
Maven fails with:

it boils down to
/usr/lib/jvm/java-6-openjdk/jre/bin/java -Xmx384m -classpath
/home/kristian/.m2/repository/org/jruby/jruby-complete/1.4.0/jruby-complete-1.4.0.jar
org.jruby.Main -S rake spec

does not work and produces your error.

but if you install rspec gem with the install-gems goal things work
(with me).

Hi,

Thanks for filing the bugs!

I can easily reproduce the problem. It all boils down to the fact that
rake tries to execute rspec via external system() call, with
parameters like this:

file:/D:/work/jruby-dev/jruby/lib/jruby-complete.jar!/META-INF/jruby.home/bin/jruby.exe
-I"lib"
“file:/D:/work/jruby-dev/jruby/lib/jruby-complete.jar!/META-INF/jruby.home/lib/ruby/gems/1.8/gems/rspec-1.2.9/bin/spec”
“./spec/t_spec.rb”.

Naturally, this is one ugly-looking command line! :slight_smile: The first
argument (the executable) is dealt with JRuby’s in-process launching
magic, so we don’t try to execute that binary, we just launch
in-process. The actual script, the third argument, is also not pretty:

“file:/D:/work/jruby-dev/jruby/lib/jruby-complete.jar!/META-INF/jruby.home/lib/ruby/gems/1.8/gems/rspec-1.2.9/bin/spec”

And currently JRuby can’t execute scripts from JAR files. Try to run:

jruby
“file:/D:/work/jruby-dev/jruby/lib/jruby-complete.jar!/META-INF/jruby.home/lib/ruby/gems/1.8/gems/rspec-1.2.9/bin/spec”

You’ll get an error. I’m going to add this functionality to JRuby dev
version, so you could try it out.

Thanks,
–Vladimir

P.S. Actually, on Windows there is another problem, our in-process
magic doesn’t actually work there, since we don’t expect “jruby.exe”,
we only look for “ruby”. Will file a separate issue for that one. But
once both these issues fixed, you should be able to execute rake from
jruby-complete, and it will properly launch rspec.

OK, so both bugs have been fixed:

And executing the spec task via rake from jruby-complete.jar should
work now, verified on Windows and Linux.
