Jenkins - Erro ao buildar pelo MSBuild

Quando tento buildar pelo Jenkins ocorre o seguinte erro:

12:13:19 Core\\LicenseManager.cs(209,51): error CS0103: The name 'License' does not exist in the current context [C:\\T1Development\\T1\\Development\\T1\\Source\\T1.CoreBusiness\\CoreBusiness9.csproj] 12:13:19 Core\\LicenseManager.cs(450,55): error CS0103: The name 'License' does not exist in the current context [C:\\T1Development\\T1\\Development\\T1\\Source\\T1.CoreBusiness\\CoreBusiness9.csproj]

Alguém tem ideia do que poderia ser ?
