eCRM uses several open source projects.

When the open source project changes I need to get those changes, build the code on my machine and then copy the new dll's into eCRM's DependentFiles/<ProjectName> folder.

I have this somewhat automated using ruby (more specifically rake)

Here is a simple class called LibCopy

class LibCopy

  def copy(lib_files, lib_build_dir)
    libs_in_use = lib_files
    libs_in_use.each do |lib|
      puts "Check for " + lib
      lib_file = lib_build_dir + "/" +  lib.pathmap("%f") 
      if File.exists?(lib_file)
        puts "Found " + lib_file
        cp lib_file, File.expand_path(lib.pathmap("%p"))
      else
        puts "lib not found:" + lib_file 
      end
    end
  end
end

And then the way I use this is like so

task :castle_to_ecrm do
    dest_castle_libs = FileList['./ecrm/DependentFiles/Castle/*']
    LibCopy.new.copy(dest_castle_libs,CASTLE_BUILD_DIR)
end
