Skip asset pre-compilation when deploying if the assets didn't change

rescue

end
if err_no || capture("cd #{latest_release} && #{source.local.log(from)} vendor/assets/ app/assets/ | wc -l").to_i > 0
run %Q{cd #{latest_release} && #{rake} RAILS_ENV=#{rails_env} #{asset_env} assets:precompile}
else
logger.info "Skipping asset pre-compilation because there were no asset changes"
