How to invoke the same msbuild target twice with different parameters from within msbuild project file itself

Question

I have the following piece of msbuild code:

  
    C:\\DirA\\
    C:\\DirB\\
           


        

Answer 1

Yes, what you want is called batching in MSBuild. The

;%(Dirs.Identity)

Defined in the Outputs will cause this task to be executed for each item in the Dirs ItemGroup.

Outputs:

Build started 8/19/2009 10:11:57 PM.
Project "D:\temp\test.proj" on node 0 (default targets).
  C:\DirA
CopyFiles:
  C:\DirB
Done Building Project "D:\temp\test.proj" (default targets).

Change the Message task to Copy task with the following condition and you are done:

Condition="Exists('%(Dirs.Identity)') AND '@(FilesToCopy)' != ''"
