Question

我想在调用MSBuild 3.5时输出当前时间（最好在每个任务之前或至少在开始/完成每个目标时）。

我尝试创建一个我会不断调用的目标：

<Target Name="EchoTime">
    <Time Format="yyyy-MM-dd HH:mm:ss.fff">
        <Output TaskParameter="FormattedTime" PropertyName="currentTime" />
    </Time>
    <Message Text = "$(currentTime)" />
</Target>

...但事实证明，每次执行一个目标只能调用另一个目标。

所以，如果我尝试......

<Target Name="TimeTest" >
    <Message Text = "--------------------------------------------------" />
    <CallTarget Targets="EchoTime" />
    <Message Text = " " />
    <Message Text = "Try calling EchoTime again" />
    <Message Text = " " />
    <CallTarget Targets="EchoTime" />
    <Message Text = "--------------------------------------------------" />
</Target>

然后输出看起来像......

Build started 10/12/2011 2:24:52 PM.
Project "C:\Temp\MSBuildSandbox\MSBuild_EchoTime.xml" on node 0 (TimeTest target(s)).
  --------------------------------------------------
EchoTime:
  2011-10-12 14:24:52.756
TimeTest:

  Try calling EchoTime again

  --------------------------------------------------
Done Building Project "C:\Temp\MSBuildSandbox\MSBuild_EchoTime.xml" (TimeTest target(s)).

任何人都知道一个简单的方法来实现这个目标吗？

CallTarget无法执行相同的目标两次，但使用MSBuild任务有workaround：

<Target Name="TimeTest" >
    <Message Text = "--------------------------------------------------" />
    <MSBuild 
        Targets="EchoTime" 
        Projects="$(MSBuildProjectFile)" 
        Properties="prop1=val1" 
    />
    <Message Text = " " />
    <Message Text = "Try calling EchoTime again" />
    <Message Text = " " />
    <MSBuild 
        Targets="EchoTime" 
        Projects="$(MSBuildProjectFile)" 
        Properties="prop1=val2" 
    />
 <Message Text = "--------------------------------------------------" />
</Target>

请注意，为每个后续呼叫将prop1的值设置为不同的值。

有没有办法在MSBuild（版本3.5）中轻松输出当前时间？
