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 lik=
e
so:

export PATH=3D$PATH:/home/lesliev/data/bin/netbeans-6.5/ruby2/jruby-1.1.4/b=
in
export PATH=3D$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
=3D=3D=3D 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" <script>:1:
file:/home/lesliev/monkey/ummpcomposer/package/jar/ChangeMe.jar!/main.class=
:1:
Invalid char `\276' ('=BE') in expression (SyntaxError)
from <script>:1:in `require'
from <script>:1
...internal jruby stack elided...

which I assume is because of this:
http://jira.codehaus.org/browse/...
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 an=
d
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 =20
on setting up Rawr to be a JRuby only gem. This is so we can ride some =20=

of JRuby's code, such as classpath name mangling for the compiler, and =20=

perhaps the compiler itself (so you don't get incompatible versions =20
between your runtime JRuby and your environment JRuby in terms of what =20=

you compiled).

You can use jruby -S to invoke a script from JRuby's bin. For example, =20=

jruby -S gem install rawr

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 # =20
recompile the files
2) Find out if your environment JRuby differs from your runtime JRuby: =20=

jruby -v; java -jar lib/java/jruby-complete.jar -v
You may need to ensure these are the same by upgrading the version =20
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 =20
fixes certain problems. I believe 1.1.7 was just released.
3) Turn off Ruby compilation in your build configuration. All this =20
will do is copy the Ruby files into the jar. The end result should be =20=

that the startup time is a little slower than compiled mode (JRuby =20
will compile these files are they are required instead of having them =20=

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, =20=

jrake, etc. Remembering where to install gems (did I update this gem =20
in MRI or JRuby?) was a problem at first, but that was the only =20
heartache I remember.

I just had a chance to actually read the ticket. I would upgrade the =20
JRuby that's on your path (or just drop in a new one and put that on =20
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.
