生日快乐！

我正在尝试使用 AWS 开发人员工具为 Flutter android 应用程序创建 CI/CD 管道。但我无法使用 AWS Codebuild 编译 apk 包。你能帮帮我们吗？

设置非常简单。 enter image description here

为简单起见，我使用了 Flutter HelloWorld dart 代码

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Welcome to Flutter',
      home: Scaffold(
        appBar: AppBar(
          title: Text('Welcome to Flutter'),
        ),
        body: Center(
          child: Text('Hello World'),
        ),
      ),
    );
  }
}

buildspec.yml

version: 0.2
phases:
  install:
    runtime-versions:
      android: 29
      java: openjdk8
    commands:
      - pwd
pre_build:
    commands:
      - echo Pre Build started on `date`
      - git clone https://github.com/flutter/flutter.git -b stable
      - export PATH="$PATH:`pwd`/flutter/bin"
      - flutter precache
      - flutter doctor
build:
    commands:
      - echo Build started on `date`
      - flutter build apk
      - ls -al
post_build:
    commands:
      - echo Build completed on `date`
artifacts:
  files:
    - "**/*"

CodeBuild 过程成功，但每次运行后它都会创建新的随机名称输出工件，但不会创建 .apk 文件。

我尝试了几种组合，但最终都出现了错误。

artifacts:
  files:
    - "**/app-release.apk"

与

artifacts:
  type: apk
  files:
    - "**/*"

找到解决方案。将工作目录更改为 helloworld 后，我设法编译了 apk 文件。

正确的 buildspec.yml 应该如下所示：

version: 0.2
phases:
  install:
    runtime-versions:
      android: 29
      java: openjdk8
    commands:
      - pwd
  pre_build:
    commands:
    - echo Pre Build started on `date`
    - git clone https://github.com/flutter/flutter.git -b stable
    - export PATH="$PATH:`pwd`/flutter/bin"
    - flutter precache
    - flutter doctor
  build:
    commands:
    - cd helloworld
    - pwd
    - ls -al
    - echo Build started on `date`
    - flutter build apk
  post_build:
    commands:
      - echo Build completed on `date`
artifacts:
  files:
  - helloworld/build/app/outputs/flutter-apk/app-release.apk
  discard-paths: yes
