如何编辑和重新运行只有失败的构建阶段？(How to edit and re-run only the build stage that failed?)

我试图让EF Migrations在VSTS上工作，这涉及到很多反复试验和错误的目录路径和命令行参数。 我的构建阶段运行迁移是：

使用NuGet 4.3.0 NuGet恢复 构建解决方案 测试组件 发布符号路径 运行EF迁移（命令行任务）

大约需要6分钟才能到达第6阶段，仅仅因为它会失败。 有什么办法可以冻结第1-5阶段的结果，只需编辑并重新运行我正在编辑的阶段？

（我试过禁用阶段1-5，但是当然没有任何DLL用于迁移运行）

I'm trying to get EF Migrations working on VSTS which is involving a lot of trial and error changing directory paths and command line arguments. My build stages up to running the migrations are:

Use NuGet 4.3.0 NuGet Restore Build solution Test Assemblies Publish symbols path Run EF Migrations (a command line task)

It takes about 6 minutes to get to stage 6, only for it then to fail. Is there any way to freeze the results of stages 1-5 and just edit and rerun the stage I'm editing?

(I've tried disabling Stages 1-5, but there are then of course no DLLs present for the migrations to run)

最满意答案

如果您使用私人代理 ，则可以冻结步骤1-5的结果，并直接运行步骤6（运行EF迁移）。

在获取源代码步骤中，您只需将clean设置为false即可实现以下功能：

如果您使用托管代理 ，则生成结果无法冻结，只能用于当前生成。

但是您可以添加多个命令行任务以重新运行第6步。详细设置如下（假设失败时重新运行EF Migrations 3次）：

在步骤6（运行EF迁移）之后，克隆命令行任务（运行EF迁移）两次：

运行EF Migrations clone1（命令行任务）

运行EF Migrations clone2（命令行任务）

然后设置步骤7和步骤8 将此任务选项设置为仅当之前的任务失败时 。

所以EF Migrations命令最多运行3次。

If you are using private agent, you can freeze the result of step1-5, and run step 6 (Run EF Migrations) directly.

In Get sources step, you just need to set clean as false to achieve that:

If you are using Hosted agent, the build result can not freezed, it can only be used for current build.

But you can add multiple Command Line tasks to re-run step 6. Detail settings as below (assume re-run EF Migrations 3 times if it’s failed):

After the step 6 (Run EF Migrations), clone the Command Line task (Run EF Migrations) for twice:

Run EF Migrations clone1 (Command Line task)

Run EF Migrations clone2 (Command Line task)

And then set step 7 and step 8 Run this task option as Only when a previous tasks has failed.

So EF Migrations command will run 3 times at most.
