We can't use TFS plugin on a project using configuration matrix. We've tried two different scenarios and both failed. It works fine on a project without a matrix.

For the following scenarios consider the configuration axes:
DB_PLATFORM ORACLE, SQL
TARGET_APP APP1

Also:

• Using ANT to build project.
• There´s no slave machines configured.

=================
Scenario 1 - Using Team Foundation Server with flag "Use update" checked.
=================

Problem description:
Jenkins can´t find build.xml file to start the job related to a matrix configuration combination. It does a successful "tf get" from the TFS workspace corresponding to the main job folder, but "tf get" to others configuration matrix does not get any file, raising an error.

MainJob console output:
=======================
Any file is downloaded at this time because a prior 'tf get' was executed and any file was updated in the server.

===========
Scenario 2 - Like scenario 1, but flag "use update" is unchecked
===========

Problem description:
It´s not possible to map a child TFS workspace to a work folder, because this folder is already mapped to the TFS workspace related to the main (or upstream) job. This TFS workspace was created by Jenkins in the same job execution.
