在上篇博客[Cake] 1. CI中的Cake中介绍了如何在CI中利用Cake来保持与CI/CD环境的解耦。
1. 简化cake的安装
当时dotnet 2.1还未正式发布,dotnet 还没有工具的支持,使得安装cake非常麻烦。不过随着 dotnet tool 的加入,这一问题得到了很好的解决。目前安装cake(0.30.0版本之后)只需要一行命令即可:
1 dotnet tool install -g cake.tool
然后就可以使用cake了。用 dotnet cake 或者 dotnet-cake 都可以,推荐使用前者。
1 $ dotnet cake --help 2 3 Usage: Cake.exe [script] [--verbosity=value] 4 [--showdescription] [--dryrun] [..] 5 6 Example: Cake.exe 7 Example: Cake.exe build.cake --verbosity=quiet 8 Example: Cake.exe build.cake --showdescription 9 10 Options: 11 --verbosity=value Specifies the amount of information to be displayed. 12 (Quiet, Minimal, Normal, Verbose, Diagnostic) 13 --debug Performs a debug. 14 --showdescription Shows description about tasks. 15 --showtree Shows the task dependency tree. 16 --dryrun Performs a dry run. 17 --exclusive Execute a single task without any dependencies. 18 --bootstrap Download/install modules defined by #module directives 19 --version Displays version information. 20 --info Displays additional information about Cake execution. 21 --help Displays usage information.
2. 简化cake的引导脚本
上一篇博客[Cake] 1. CI中的Cake中出现的cake的引导脚本 build.ps1 和 build.sh ,绝大部分代码都是在下载安装cake用的,既然有了上面的 dotnet tool 命令可以安装cake,那么当然也就可以简化一下了。
引导脚本中包含安装和执行命令的代码。nuget相关的环境变量是项目需要的,cake脚本可以读取这些信息来使用。
2.1 cake.ps1
1 [string]$SCRIPT = '0-build/build.cake' 2 [string]$CAKE_VERSION = '0.33.0' 3 4 # nuget server config 5 $ENV:NUGET_REPOSITORY_API_URL = "http://nuget-server.test/nuget" 6 $ENV:NUGET_REPOSITORY_API_KEY = "123456" 7 8 # Install cake.tool 9 dotnet tool install --global cake.tool --version $CAKE_VERSION 10 11 # Start Cake 12 [string]$CAKE_ARGS = "-verbosity=diagnostic" 13 14 Write-Host "dotnet cake $SCRIPT $CAKE_ARGS $ARGS" -ForegroundColor GREEN 15 16 dotnet cake $SCRIPT $CAKE_ARGS $ARGS
查看一下cake脚本都有哪些task:
1 $ .cake.ps1 --showtree 2 Tool 'cake.tool' is already installed. 3 dotnet cake 0-build/build.cake -verbosity=diagnostic --showtree 4 5 .... 6 7 default 8 └─test 9 └─build 10 ├─clean 11 └─restore 12 13 push 14 └─pack 15 └─test 16 └─build 17 ├─clean 18 └─restore
2.2 cake.sh
1 #!/bin/sh 2 3 SCRIPT='0-build/build.cake' 4 CAKE_VERSION='0.33.0' 5 6 # nuget server config 7 export NUGET_REPOSITORY_API_URL='http://nuget-server.test/nuget' 8 export NUGET_REPOSITORY_API_KEY='123456' 9 10 # Install cake.tool 11 dotnet tool install --global cake.tool --version $CAKE_VERSION 12 export PATH="$PATH:$HOME/.dotnet/tools" 13 14 # Start Cake 15 CAKE_ARGS="$SCRIPT -verbosity=diagnostic" 16 17 echo "
