In rake how do I call a subdir Rakefile

Question

In ant I'd do the following

 <target name="subclient" >
     <ant antfile="suddir/build.xml" target="target1" useNativeBasedir="true"/>
 </target>

How do I do this sort of thing in JRuby/Rake

Answer 1

You can simply use Dir.chdir and launch a rake subprocess:

def rake(*args)
  ruby "-S", "rake", *args
end

task :subrake do
  Dir.chdir("subproject") do
    rake
  end
end
