raven, rake, ant and ruby

[Thufir]

I don't really know how to put these together. What I do know is that my
previous experience with ant was that I found it awkward, so I'd rather
use rake. I'm not so sure about raven if only because I'm not convinced
that JRuby is viable and that if I run into a problem there may be no
solution, or that I won't be able to find it in a timely fashion.

I'm inclined to go with rake and ruby, but don't know how to get started
with rake. What would be the first step in creating a rake compile task
from Tasks.compile ?

thufir@arrakis:~/java$
thufir@arrakis:~/java$ cat tasks.rb
#/usr/bin/ruby

require 'fileutils'
module Tasks

JAVA = "/home/thufir/java/"
SRC = "src/"
BUILD = "build/"
COM = "com/"
WEB_TOMORROW = "web_tomorrow/"
PACKAGE = "package/"

def Tasks.clean
puts "\n\nclean...\n"
Dir.chdir("#{JAVA}")
puts "working directory:\t\t" + Dir.getwd + "\n\n"

FileUtils.rm_rf("#{BUILD}")
FileUtils.rm_rf("#{PACKAGE}")

Dir.mkdir("#{BUILD}")
Dir.mkdir(File.join(BUILD, COM))
Dir.mkdir(File.join(BUILD, COM, WEB_TOMORROW))
Dir.mkdir("#{PACKAGE}")

end


def Tasks.compile
puts "\n\ncompile...\n\n"
Dir.chdir(File.join(JAVA,SRC))
puts "working directory:\t\t" + Dir.getwd + "\n\n"
system("javac -cp . -d #{JAVA}#{BUILD} com/web_tomorrow/
CPTest2.java ")
end

def Tasks.create_manifest
puts "\n\ncreate_manifest...\n\n"
Dir.chdir(File.join(JAVA,BUILD))
File.open( 'manifest.txt', 'w' ) {
|f|
f.write("Main-Class:
com.web_tomorrow.CPTest2\n\n")
}
end


def Tasks.package
puts "\n\npackage...\n\n"

create_manifest

Dir.chdir("#{JAVA}")
puts "working directory:\t\t" + Dir.getwd + "\n\n"
# FileUtils.cp("/home/thufir/java/manifest.txt", "/home/
thufir/java/build/manifest.txt")
Dir.chdir("#{BUILD}")
puts "working directory:\t\t" + Dir.getwd + "\n\n"
system("jar -cfmv foo.jar manifest.txt com/web_tomorrow/
*.class")
FileUtils.mv("/home/thufir/java/build/foo.jar", "/home/
thufir/java/package/foo.jar")
end


def Tasks.examine_jar
puts "\n\nexamine_jar...\n\n"
Dir.chdir("#{BUILD}")
puts "working directory:\t\t" + Dir.getwd + "\n\n"
system("jar -tf foo.jar")
system("jar -xf foo.jar META-INF/MANIFEST.MF")
system("cat META-INF/MANIFEST.MF -n")
end


def Tasks.test
puts "\n\ntest...\n\n"
Dir.chdir("#{JAVA}")
Dir.chdir("#{PACKAGE}")
puts "working directory:\t\t" + Dir.getwd + "\n\n"
system("java -jar foo.jar")
end

end

Although they seem to have lost their stylesheets for the last while,
rake has fine documentation at
http://docs.rubyrake.org/

but, to start, rake tasks basically look like
desc 'Compile the program from the Java sources'
task :compile do
compile_my_program
end

I suggest looking at buildr: http://incubator.apache.org/buildr/

I read the tutorial at http://www.railsenvy.com/2007/6/11/ruby-on-rails-rake=
-tutorial
and came up with:

C:\code>
C:\code>rake all
(in C:/code)
clean
compile
jar
test
all

C:\code>
C:\code>type rakefile.rb
task :clobber do
puts "clobber"
end

task :clean do
puts "clean"
end

task :compile =3D> :clean do #really not a dependancy, but my
programs are small, so shouldn't matter
puts "compile"
end

task :jar =3D> :compile do
puts "jar"
end

task :test =3D> :jar do
puts "test"
end


task :all =3D> :test do
puts "all"
end

C:\code>
C:\code>

which looks promising, I think I can convert my ruby script to a rake
file

On ubuntu, at least, I can't get the required gems to install correctly.
So, sticking with rake for the time being.

thank you, though.

I had some difficulty installing buildr too (actually a problem compiling
rjb) but managed to get it working by installing some missing libraries:

sudo apt-get install ruby
sudo apt-get install ruby1.8-dev
sudo apt-get install build-essential
sudo apt-get install libopenssl-ruby

sudo gem install --source http://gems.tron.name/gems.rubyforge.org/ buildr

(from the discussion here
http://groups.google.com/group/buildr-talk/browse_thread/thread/640f9903f0a3f290/437e14f8367be1fc
