You can actually debug MSBuildscripts with Visual Studio 2010 now. It requires some hacking, and it isn't officially supported, but it is an option.
您现在实际上可以使用 Visual Studio 2010调试 MSBuild脚本。它需要一些黑客攻击，并且它不受官方支持，但它是一种选择。
Otherwise use the Messagetask. Normal rules for referencing Properties, Itemsand Item Metadata(also referred to as batching) apply.
否则使用Message任务。用于引用一般规则Properties，Items和Item Metadata（也被称为配料）申请。
This example:
这个例子：
<Project DefaultTargets="Build"
xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<ItemGroup>
<TestItem Include="test1" />
<TestItem Include="test2" />
<TestItem Include="test3" />
</ItemGroup>
<PropertyGroup>
<TestProperty>Property Value</TestProperty>
</PropertyGroup>
<Target Name="TestMessage" AfterTargets="Build" >
<!-- Use $(Property Name) to reference a property -->
<Message Text="$(TestProperty)" Importance="high"/>
<!-- Use @(Item Name) to output a semi-colon
separated list of items on one line -->
<Message Text="@(TestItem)" Importance="high"/>
<!-- Use %(Item Name.Metadata Property Name) to
call the Message task once for each item. -->
<!-- This will output each item on a separate line -->
<Message Text="%(TestItem.Identity)" Importance="high"/>
</Target>
</Project>
Will produce this output:
将产生此输出：
Property Value
test1;test2;test3
test1
test2
test3
