Re: [rawr] rawr failure with mixed ruby/java packages

[Logan Barnett]

Bruce,

I think I have the time to look into to this (Rawr and Monkeybars doesn't get a ton of love these days). Just so I understand clearly, this happens with the NestedSimple example? If not, can you give me a git link for your example where it breaks?

I'm having difficulty using rawr. The problem occurs under certain
circumstances, during the creation of the target jar file: the rake task
aborts. The key portions of the rawr output look like this (I include
the full output further down):

=== Creating jar file: package/jar/rawrtest.jar
Error during the creation of the jar file: package/jar/rawrtest.jar
rake aborted!
add failed. Entry rawrtest already exists

I'm using Jruby v. 1.7.3, with Java 1.7.0_17-b02
rawr v. 1.6.4 and monkeybars v. 1.1.2
Running in Win7 x64, but with the 32-bit version of Java.

The build_configuration.rb includes the following settings:
    c.executable_type = "console"
    c.compile_ruby_files = false
    c.target_jvm_version = 1.7

The project I'm using here is a very simple "hello world" style
console program. The src directory contains a file, main.rb,
with a single puts in it, org/monkeybars/rawr/Main.java, and
one other subdirectory, rawrtest, with two files in it. Neither file
is actually called from main.rb, all that matters is that one is a
ruby file and the other is a java file. The src/rawrtest subdirectory is
the rawrtest that "already exists" in the error message above.

What I mean by "all that matters" is that, if src/rawrtest only contains
the java file (not the ruby file), then rawr runs properly, and
produces executables the execute properly. If src/rawrtest contains
only the ruby file, rawr executes properly. If src/rawrtest contains
neither file (it is empty), rawr executes properly. It is only when
it contains *both* the java file and the ruby file that rawr fails.
Note: the java file is jextra.java, the ruby file is rextra.rb, so
they do not have the same filename (pre-extension).

In the rawr code, the error arises during the execution of the
following line, near the bottom of rawr-1.6.4\lib\rawr\jar_builder.rb:
            zipfile.add(file_path_in_zip, src_file_path)

I've included the complete output from the failed rawr task below.
In the output, there are lines prefixed with BBT: those are from
a puts that I added to jar_builder.rb on the line before the
zipfile.add line, showing the file_path_in_zip and src_file_path
values for each iteration.
I believe that they key lines to observe are the last BBT line before
the error, and two lines before that one. Both lines have the same
file_path_in_zip=rawrtest, coming from different src_file_path values.

At this point, I want to toss this to someone with more familiarity
than me about how rawr is supposed to work. I assume that this is
not expected behavior from rawr (I first ran into this when trying
to run rawr on the Nested-Simple project contained in the monkeybars
gem). What is the best fix for this?
