Jenkins windows从机无tty分配故障

我可能在解决在windows从属服务器上构建Jenkins作业的问题时遇到了障碍。我不确定需要做什么来解决以下问题？这是日志

我认为下面的日志消息表明了故障，我不确定如何修复它

2 [main] sh 140924 tty_list::allocate_tty: No tty allocated, 

谷歌快速搜索指向我，但我无法通过从

CYGWIN

环境变量中删除

tty

来解决这个问题

如果有人能解释这一失败的原因和修复步骤，那就太好了

…这是Jenkins构建作业将执行的shell命令

./update-repo.sh
