echo All Elements of an ItemGroup

I have an MSBuild ItemGroup and I would like to be able to echo it out in the "Post-Build Event".

However when I try commands like: echo My ItemGroup: @(Foo)

I get the error:

error MSB4164: The value "echo My ItemGroup: @(Foo)" of metadata "Command" contains an item list expression. Item list expressions are not allowed on default metadata values.

I'm not very good with ItemGroups as of yet. Is there a way I can just echo the list of files that Foo contains?

Solution

  • You'll want something like:

    <ItemGroup>
  <ForcedUsingFilesList Include="c:\path\to\files\*" />
</ItemGroup>
<Target Name="MyTarget">
  <PropertyGroup>
    <MyFiles>
        @(ForcedUsingFilesList->'%(FullPath)')
    </MyFiles>
  </PropertyGroup>
  <Exec>echo $(MyFiles)</Exec>
</Target>
