TFS 2017 - how build/deliver only changed files?

Solution 1:

Lets assume how I solved this problem (if anyone has similar problem):

Since TFS 2017 always delivered all files - changed and unchanged, but I need only changed, I solved this as follows:

Since files that are transferred to Artifact keep timestamp (unchanged files have last_edited timestamp, and edited files have new, current timestamp) I decide to create FIXED Artifact directory (not depending on build version, but always the same). Then I wrote PowerShell script (as a first Release step ) which deletes all files (recursive) which have timestamp that is < (Now - x min), and all empty directories after that. On this way Artifact directory contains of ONLY CHANGED files (entire file structure (of changed files) is kept). Now Release will deliver only these files to destination.

Cheers! :)

Solution 2:

If you want to have an incremental build. When you add a Visual Studio Build / MSBuild task to build the project, just uncheck the Clean option. Thus it will sync the source and only get the changed files from the second time to build. See Build task Arguments for details.

Clean Option : Set to False if you want to make this an incremental build. This setting might reduce your build time, especially if your codebase is large. This option has no practical effect unless you also set Clean repository to False.

Set to True if you want to rebuild all the code in the code projects. This is equivalent to the MSBuild /target:clean argument.

Assuming you want to deliver the only changed files to a specific location, you can add a Copy Files step to copy the changed files to the location.
