我正在尝试将代码从GitHub部署到AWS Amazon中的CodeDeploy。 我有示例HelloWorld应用程序。我有如下所示的appspec.yml：

os: linux

files:
  - source: /
    destination: /home/ec2-user/server

permissions:
  - object: /
    pattern: "**"
    owner: ec2-user
    group: ec2-user

hooks:
  ApplicationStop:
    - location: stop.sh
      timeout: 20
      runas: ec2-user
  ApplicationStart:
    - location: start.sh
      timeout: 20
      runas: ec2-user
  ValidateService:
    - location: validate.sh
      timeout: 120
      runas: ec2-user

和buldspec.yml：

phases:
  install:
    runtime-versions:
      java: openjdk8
  build:
    commands:
      - mvn clean package --quiet
artifacts:
  discard-paths: yes
  files:
    - target/*
    - scripts/*
    - appspec.yml

start.sh

cd /home/ec2-user/server
sudo /usr/bin/java -jar -Dserver.port=80 \
    *.jar > /dev/null 2> /dev/null < /dev/null &

stop.sh：

#!/usr/bin/env bash

sudo killall java
exit 0

和validate.sh：

#!/bin/bash

echo "Waiting for 15 seconds before checking health.."
sleep 15

status_code=$(curl --write-out %{http_code} --silent --output /dev/null http://localhost:80)
if [[ "$status_code" -ne 200 ]] ; then
  echo "App is not healthy - $status_code"
  exit 1
else
  echo "App is responding with $status_code"
  exit 0
fi

我的部署失败，错误提示：

位于指定位置的脚本：以用户ec2-user身份运行的start.sh失败，退出代码为127 日志 LifecycleEvent-ApplicationStart 脚本-start.sh [stderr] / usr / bin / env：bash：没有这样的文件或目录

请有人可以帮助我
