MSBuild Message Output Twice - tfs

Question

I have the following Target:
<Target Name="SetBinariesLocationForTeamBuild">
<!--We add the following location paths because TFS Team Build first copies to \sources and \binaries folders
rather than simply having the binaries in a \bin folder of the source folder
at this point the build will be at: C:\Builds\3\x.Int.MIS\SupportBTDF\Sources\x.Int.MIS\Dev\V1.0\Src\Solutions\MIS\x.Int.MIS.Deployment
so we need to go up 4 levels before going back down to binaries-->

I run the project from the command line passing in /p:TeamBuild=True /t:SetBinariesForTeamBuild. The output has me very puzzled...

I want the location path to be the one with 8 ..\ but it is not - any idea why and why it gets printed twice!?

Answer 1

The #(Schemas) and #(Pipelines) item arrays are each getting another item tuple added to them, or else they couldn't be printing out. There must be another target that is getting run in which this happens. If you are running msbuild on the project using the exact command line, then the additional target would have to be either an entry in an InitialTargets on a Project, or else a target wired into the target above with a BeforeTargets or AfterTargets reference to this one.
