MSBuild:如何创建包含多个<Exec>任务的参数化内联任务

我有以下简单的任务:

<Exec Command="  icacls   &quot;$( [System.IO.Path]::Combine( $(_tempPublishUrl), Logs              ))&quot;  /grant      Users:(CI)(OI)M  /T  "  ContinueOnError="true" />
<Exec Command="  icacls   &quot;$( [System.IO.Path]::Combine( $(_tempPublishUrl), Logs              ))&quot;  /grant  IIS_IUSRS:(CI)(OI)M  /T  "  ContinueOnError="true" />

<Exec Command="  icacls   &quot;$( [System.IO.Path]::Combine( $(_tempPublishUrl), ReportResults     ))&quot;  /grant      Users:(CI)(OI)M  /T  "  ContinueOnError="true" />
<Exec Command="  icacls   &quot;$( [System.IO.Path]::Combine( $(_tempPublishUrl), ReportResults     ))&quot;  /grant  IIS_IUSRS:(CI)(OI)M  /T  "  ContinueOnError="true" />

<Exec Command="  icacls   &quot;$( [System.IO.Path]::Combine( $(_tempPublishUrl), ReportTemplates   ))&quot;  /grant      Users:(CI)(OI)M  /T  "  ContinueOnError="true" />
<Exec Command="  icacls   &quot;$( [System.IO.Path]::Combine( $(_tempPublishUrl), ReportTemplates   ))&quot;  /grant  IIS_IUSRS:(CI)(OI)M  /T  "  ContinueOnError="true" />

<UsingTask
  TaskName="RenameDirectory"
  TaskFactory="CodeTaskFactory"
  AssemblyFile="$(MSBuildToolsPath)\Microsoft.Build.Tasks.v4.0.dll"
>
  <ParameterGroup>
    <PathToDirToRename          ParameterType="System.String"    Required="true" />
    <PathToNewDirectoryName     ParameterType="System.String"    Required="true" />
  </ParameterGroup>

  <Task>
    <Reference  Include="System.Core" />
    <Using Namespace="System" />

    <Code Type="Fragment" Language="cs">
      <![CDATA[
          System.IO.Directory.Move(PathToDirToRename, PathToNewDirectoryName);
      ]]>
    </Code>
  </Task>
</UsingTask>

但我如何才能雇用<使用任务>将我的<分组;执行官>任务以创建一个可重用的任务(想想函数)?我找不到这样的例子。
