VSTS - build one of many projects from solution

Question

I want to centralize in a same VisualStudio solution a lot of projects: - API.Core (library class) - API.Mobile (.NET Core project) - API.Web (.NET Core project) - Database (SQL Server Database Project) - Functions (Azure Functions)

For each project except the library classes, I want to configure a build definition but I'd like to trigger the build if and only if I changed a portion of code of a project. Ex: I made some modifications in API.Web => so I want the build definition of API.Web to trigger only and not the others.

Is it possible ?

Answer 1

When setting up CI, you can setup a Path filter. this will result in the build only triggering when files are changed in that specific path

Answer 2

The simple way is using multiple build definitions, each build definition for a project.

Then as Remco said that, set the Path filters for each project in the build definition, then specify the corresponding project file or /t:{project} msbuild argument to just build the related project.

For example,

Build definition name: BuildDefForAPICore

Path filter: the path for API.Core project folder

Choose API.Core.csproj file in Visual Studio Build task.
