并行生成终止使子MSBuild.exe进程运行 [英] Parallel Build Termination Leaves Child MSBuild.exe Processes Running

问题描述

大家好，

我们将构建嵌入式代码封装在MSBuild项目文件中，预定义了适当的依赖项，以并行运行它们并减少构建时间.

We encapsulated building embedded code in MSBuild project files, predefining the proper dependencies, to run them in parallel and reduce build time.

运行良好，时间明显减少，直到我们注意到使用CTRL-BREAK终止命令行构建导致主MSBuild.exe进程停止，但子进程继续运行.使用Process Explorer，您可以看到 生成的MSBuild(通过Exec任务)如何在后台运行.我认为一旦完成被调用的任务，它们就会消失.无论如何，如果开发人员尝试启动另一个构建，这将是有问题的.

It was working beautifully with significant reduction in time until we noticed that terminating the command-line build with CTRL-BREAK caused the main MSBuild.exe process to stop but the child processes kept on running. Using Process Explorer, you can see how the MSBuild-spawned (via the Exec task) kept on running in the background. I assume they would go away once the called task is done. Anyway, this would be problematic if the developer tried to initiate another build.

我的问题是:

• 这是取消构建的预期行为吗?对于Visual Studio项目的并行编译，是否也存在此问题?
• 是否有更干净的方法来取消构建? (父MSBuild进程是否以某种方式指示子进程停止?)

• Is this the expected behavior from canceling a build? Does this problem exist for parallel compilation of Visual Studio projects as well?
• Is there a cleaner way to cancel the build? (Have the parent MSBuild process somehow signal the child ones to stop?)

我假设，如果一个Exec任务调用进程之一自然失败，那么构建将正常停止(所有MSBuild进程都将消失).

I assume if one of the Exec task-called processes failed naturally, then the build would stop gracefully (all MSBuild processes disappear).

提前谢谢！

 

推荐答案

Hi Dashrendar ，

 

感谢您的信息.

我想您将MSBuild封装到项目中以实现并行构建工具，

如果是这样，我想您可以创建一个新的线程来构建而不是建立进程，以避免该问题.
