Hi people!

I am trying to use RAWR to package a netbeans/monkeybars project, but am  
running into some bugs.

First (on version 1.1.1) I was getting:  
undefined local variable or method `processed\_file’ for main:Object

So I upgraded to 1.1.2, which apparently fixes that bug. Now I am  
getting:  
no such file to load – jruby\_fetch

This is even if I try to use ‘rake -T’ on the RAWR generated rakefile.  
So  
including RAWR is trying to load this  
mysterious jruby\_fetch gem that I cannot find any reference to anywhere.

Any help?

Les

Leslie,  
Looks like yet another bug during the release.  
Can you create an empty jruby\_fetch.rb (touch jruby\_fetch.rb) in your  
project root? I tried this after reproducing the bug, and it let me  
run the rawr:jar task after that.  
I’ll get a fix for that released on Monday.

Ok, did that. Then I get a message about a constant ‘Java’ that doesn’t  
exist - this didn’t happen before with 1.1.1.  
Anyway, so I took that as a cue to try and run everything through jruby  
like  
so:

export  
PATH=$PATH:/home/lesliev/data/bin/netbeans-6.5/ruby2/jruby-1.1.4/bin  
export PATH=$PATH:/home/lesliev/data/bin/netbeans-6.5/ruby2/jruby-1.1.4  
jruby /usr/bin/gem install -r rawr  
jruby /usr/bin/rake rawr:jar

This seems to work, I get:

(in /home/lesliev/monkey/ummpcomposer)  
Copying non-source file compose/Composer.form to  
/home/lesliev/monkey/ummpcomposer/package/classes/compose/Composer.form  
Copying non-source file README.txt to  
/home/lesliev/monkey/ummpcomposer/package/classes/README.txt  
=== Creating jar file:  
/home/lesliev/monkey/ummpcomposer/package/jar/ChangeMe.jar

…but when I try and run it:

lesliev@lesliev-laptop:~/monkey/ummpcomposer/package/jar$ java -jar  
ChangeMe.jar  
Exception in thread “main” :1:  
file:/home/lesliev/monkey/ummpcomposer/package/jar/ChangeMe.jar!/main.class:1:  
Invalid char `\276' ('¾') in expression (SyntaxError) from <script>:1:in `require’  
from :1  
…internal jruby stack elided…

which I assume is because of this:  
[http://jira.codehaus.org/browse/JRUBY-1628](http://jira.codehaus.org/browse/JRUBY-1628)  
I am running jruby 1.1.4 which came with netbeans.

So I guess I’ll keep tinkering with jruby. I’m not really sure how jruby  
and  
ruby play together on the same machine - everything runs fine in the  
Netbeans environment (my Monkeybars programs work well).

The latest Rawr is dependent on JRuby now. This weekend I’m planning  
on setting up Rawr to be a JRuby only gem. This is so we can ride some  
of JRuby’s code, such as classpath name mangling for the compiler, and  
perhaps the compiler itself (so you don’t get incompatible versions  
between your runtime JRuby and your environment JRuby in terms of what  
you compiled).

You can use jruby -S to invoke a script from JRuby’s bin. For example,  
jruby -S gem install rawr

> …internal jruby stack elided…

Something is terribly wrong there in terms of the bytecode generated.  
Things I would try:

1. jruby -S rake rawr:clean; jruby -S rake rawr:jar #  
recompile the files
2. Find out if your environment JRuby differs from your runtime JRuby:  
jruby -v; java -jar lib/java/jruby-complete.jar -v  
You may need to ensure these are the same by upgrading the version  
Netbeans is using, or making your project use the Netbeans version.  
1.1.4 is a bit old. Charles Nutter might know better than I if that  
fixes certain problems. I believe 1.1.7 was just released.
3. Turn off Ruby compilation in your build configuration. All this  
will do is copy the Ruby files into the jar. The end result should be  
that the startup time is a little slower than compiled mode (JRuby  
will compile these files are they are required instead of having them  
compiled to start with).

Please let me know how any of that works out for you.

I aliased my JRuby scripts to have a j in front. This way I have jgem,  
jrake, etc. Remembering where to install gems (did I update this gem  
in MRI or JRuby?) was a problem at first, but that was the only  
heartache I remember.

I just had a chance to actually read the ticket. I would upgrade the  
JRuby that’s on your path (or just drop in a new one and put that on  
your path instead) to 1.1.7.

Note that 1.1.7 is currently trunk and in development. You’d probably be  
better off grabbing 1.1.6.
