VS2013, falha na construção do TFS 2013

Question

Estou tentando usar o TFS build para executar um arquivo em lote 'tt.bat', é um arquivo de lote muito simples que cria uma pasta. mkdir d: \ ttt O arquivo de lote está funcionando corretamente, mas quando eu construí-lo com o VS 2013 eu tenho erro aqui está o log:
