使用 .NET 6 和发布命令成功安装具有 .NET 8 SDK 的 CodeBuild 项目

Question

我们正在使用 AWS 提供的

aws/codebuild/amazonlinux2-x86_64-standard:5.0

CodeBuild 映像，并在我们的构建规范文件中安装 .NET 8 SDK：

 /usr/local/bin/dotnet-install.sh --channel 8.0

运行成功，我们用

dotnet --list-sdks

确认并得到以下输出：

[Container] 2024/03/28 00:29:20.812199 Running command dotnet --list-sdks
6.0.419 [/root/.dotnet/sdk]
8.0.201 [/root/.dotnet/sdk]
8.0.203 [/root/.dotnet/sdk]

但是，当我们尝试使用

dotnet lambda package --configuration Release --framework net8.0 --output-package deploy-package.zip

构建/打包我们的 .NET 8 应用程序时

似乎忽略了已安装 .NET 8 SDK 的事实并选择了 .NET 6。这是不兼容且出错的。

在本地大致相同的情况下（同时安装多个 SDK 版本 [6.X.X、7.X.X 和 8.X.X] - 在本地此某些解决方案上运行

dotnet build

以及

dotnet lambda package [...]

，结果会成功。

Answer 1

最终依靠 CodeBuild 功能在

runtime-versions

阶段提供您想要的

install

。

从 buildpsec 中完全删除了步骤

/usr/local/bin/dotnet-install.sh --channel 8.0

，转而采用下面的步骤，效果很好。

version: 0.2
phases:
    install:
        runtime-versions:
            dotnet: 8.0

6 和 8 将同时可用/安装。

6.0.419 [/root/.dotnet/sdk]
8.0.201 [/root/.dotnet/sdk]

但是现在运行时

dotnet lambda package --configuration Release --framework net8.0 --output-package deploy-package.zip

使用了正确的SDK并且发布/打包成功了。
