如何两次调用同一msbuild目标? [英] How to invoke the same msbuild target twice?

问题描述

我有以下msbuild脚本:

I have the following msbuild script:

<?xml version="1.0" encoding="utf-8"?>
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003"
         DefaultTargets="All">

  <PropertyGroup>
  ...
  </PropertyGroup>

  <UsingTask AssemblyFile="$(GallioTaskPath)" TaskName="Gallio.MSBuildTasks.Gallio" />
  <Import Project="$(MSBuildCommunityTasksPath)\MSBuild.Community.Tasks.Targets" />

  <ItemGroup>
  ...
  </ItemGroup>

  <Target Name="CheckServerHostsItemGroup"
          Condition="'$(NoServerHosts)' != True">
  ...
  </Target>

  <Target Name="RunServerHosts" DependsOnTargets="CheckServerHostsItemGroup"
          Condition="'$(NoServerHosts)' != True">
  ...
  </Target>

  <Target Name="KillServerHosts" DependsOnTargets="CheckServerHostsItemGroup"
          Condition="'$(NoServerHosts)' != True">
    ...
  </Target>

  <Target Name="KillServerHosts2"
          Condition="'$(NoServerHosts)' != True">
    <MSBuild Projects="$(MSBuildProjectFile)" Targets="KillServerHosts" Properties="Configuration=$(Configuration)" />
  </Target>

  <Target Name="All" DependsOnTargets="Build;RunServerHosts;Test;KillServerHosts2">
    <OnError ExecuteTargets="KillServerHosts2" />
  </Target>

  <Target Name="Test">
    ...
    <Error Text="Tests execution failed with exit code $(ExitCode)" Condition="'$(ExitCode)' != 0" />
  </Target>

  <Target Name="CheckSolutionsItemGroup">
  ...
  </Target>

  <Target Name="Build" DependsOnTargets="CheckSolutionsItemGroup;KillServerHosts">
  ...
  </Target>

  <Target Name="Clean" DependsOnTargets="CheckSolutionsItemGroup;KillServerHosts">
  ...
  </Target>

</Project>

我删除了目标的主体以节省空间，因为它们无关紧要.但是，如果有人认为自己是，那么我会把它们包括在内.

I have removed the bodies of the targets to save space and because they are irrelevant. However, if someone thinks they are, I will include them.

无论如何，正如人们所看到的，有一个目标-KillServerHosts，我希望有两次调用，这是有充分理由的.在构建之前，一次是为了确保没有程序集被锁定，另一次是在测试完成后才能清理表".

Anyway, as one can see, there is one target - KillServerHosts, which I wish to invoke twice and for a good reason. Once before the build, in order to ensure no assemblies are locked and the other time after the tests complete to "cleanup the table".

自然，尝试两次调用目标KillServerHosts无效，MSBuild拒绝两次构建同一目标.因此，我试图通过调用目标KillServerHosts2作弊.问题在于有时它可以工作，有时却不能.

Naturally, trying to invoke the target KillServerHosts twice does not work, MSBuild refuses to build the same target twice. So, I am trying to cheat by invoking the target KillServerHosts2. The problem is that sometimes it works and sometimes it does not.

如果我从命令行运行KillServerHosts目标，它总是会杀死相关的服务器主机，因此从这一方面来看，它可以正常工作.

If I run the KillServerHosts target from the command line it always kills the relevant server hosts, so from this respect it works fine.

有什么想法吗?

推荐答案

根据设计，MSBuild目标不会多次执行.您不应将MSBuild目标视为方法或函数，因为MSBuild不是一种功能编程语言.

By design MSBuild targets are not executed more than once. You should not think of an MSBuild target as a method or function, bucause MSBuild is not a functional programming language.

如果您想多次执行目标，则可以使用MSBuild任务执行此操作，只需传入一组不同的属性即可.例如这样的东西

If you want to execute a target more than once you can use the MSBuild task to do so, just pass in a different set of properties. For example something like this

<Target Name="SomeTarget">
    <MSBuild Projects="$(MSBuildProjectFile)" Targets="YourTarget" Properties="FakeProperty=one" />
    <MSBuild Projects="$(MSBuildProjectFile)" Targets="YourTarget" Properties="FakeProperty=two" />
</Target>

注意:我实际上并没有尝试过，所以如果我拼写错误或记错了，可能会出现语法问题，但是您应该能够使它正常工作.

Note: I didn't actually try this out so there might be syntax issues if I mis-spelled or remembered incorrectly but you should be able to get it working.
