Question

当执行的命令退出状态不为0时，Capistrano不会中止。并继续部署。如何在执行的命令失败时中止部署，返回不同于0的退出状态？

我尝试过测试，执行，捕获命令但却无法实现。这是我最近测试失败的代码，我实际上正在运行真正的工作。当我尝试在远程服务器上执行时，退出状态为1.

   desc "Command to abort"
   task :aborting_command do
      on roles(:all) do |host|
            within release_path do
               execute("false")
            end
         end
      end
   end

输出：

INFO [0ea66341] Running /usr/bin/env false on remote-server.xxx
DEBUG [0ea66341] Command: cd /projectdir/releases/20160315140516 && /usr/bin/env false
INFO [0ea66341] Finished in 0.044 seconds with exit status 0 (successful).

使用--trace：

** Invoke deploy:aborting_command (first_time)
** Execute deploy:aborting_command
DEBUG [d5f30008] Running /usr/bin/env if test ! -d /projectdir/releases/20160315140254; then echo "Directory does not exist '/projectdir/releases/20160315140254'" 1>&2; false; fi on remote-server.xxx

使用Capistrano版本：3.4.0（耙版：10.4.2）

任务失败时，Capistrano不会中止部署
