团队城市中的 Dart 构建步骤

Question

我尝试在 teamcity 中创建构建步骤来构建 dart Angular 应用程序。 第一步，我运行命令行脚本：

set https_proxy=http://myproxyaddress
pub get

日志看起来像：

[18:23:46][Step 1/5] Process exited with code 0

有第一个问题：

Transformer library "package:angular/transform/codegen.dart" not found.

接下来我尝试构建：

pub build

并且有错误：

我做错了什么？如何在 teamcity 中构建 dart 项目？

pubspec.yaml：

environment:
  sdk: '>=1.24.0 <2.0.0'

dependencies:
  angular: "4.0.0-alpha"
  angular_components: "^0.6.0-alpha"
  http: ^0.11.3+14
  uuid: ^0.5.3
  stream_transformers: ^0.3.0

dev_dependencies:
  browser: '^0.10.0+2'
  dart_to_js_script_rewriter: ^1.0.3

transformers:
- angular:
    entry_points:
    - web/main.dart
    - web_test/main.dart
- $dart2js:
    commandLineOptions: [--show-package-warnings]
- dart_to_js_script_rewriter

web:
  compiler:
    debug: dartdevc

Answer 1

代理设置中的问题。

set https_proxy=http://myproxyaddress

在构建过程中，pub 尝试通过代理服务器连接到本地主机（我认为）。我们需要在系统环境或构建/获取步骤中声明no_proxy：

set no_proxy=localhost,127.0.0.0/8, <corporate addresses>

我将步骤 1 更改为：

set https_proxy=http://myproxyaddress
set no_proxy=localhost,127.0.0.0/8, <corporate addresses>
pub get

第 2 步：

set no_proxy=localhost,127.0.0.0/8, <corporate addresses>
pub build

Answer 2

首先我建议使用4.0.0（最终）而不是4.0.0-alpha

移除pubpsec.yaml 中的codegen 转换器。

transformers 部分应如下所示

transformers:
- sass_builder
- angular:
    entry_points: web/main.dart
