TFS SourcesDirectory is null/empty when used in Expression Editor

Question

I have a build definition which has two working folders specified. One of these has the following columns:

• Status: Active
• Source Control Folder: $/MyCompany/MyDivision/Solution2
• Build Agent Folder: $(SourceDir)\\Solution2

I am trying to access this Build Agent Folder from within the Expression editor in TFS 2012?

I've tried SourcesDirectory but when it gets evaluated it is null/empty. Is there something specific I need to do to get SourcesDiretory to work in the expression editor? Or is there a better way to reference this specific build agent folder in it's entirety?

Answer 1

The SourcesDirectory and indeed the BinariesDirectory are not set till later in the build. They are not immediately available at the start of the build.
