TFS on-premises agent version mismatch

[jdshkolnik]

Hi,

I'm on TFS 2015: Update 2 on my test box and Update 3 on my prod box. You require version 1.99.0 but the version available for on-premises is 1.95.x.

@jdshkolnik Quick question... are all of the build tasks in the extension failing to load or is it only the VSTS Keep task that is failing to load? For example, after installing the extension, do you see any of the "VSTS-???" tasks when you go to add a task to a build definition?

The VSTS Keep task requires 1.99 (or greater) because of an API change that was made in VSTS but has yet to be applied to TFS (on premises). If the other tasks are showing up then this would explain why you're not seeing the VSTS Keep task. However, if all tasks are failing to install then that's another issue.

Let me know if you're seeing any of the other tasks.

--- Thanks, Jeff

@jbramwell It's only that one; I see the others.

[jbramwell]

OK. Thanks! In that case, this is expected since that particular task (VSTS Keep) does not yet work for TFS on-premises. Once they update TFS with the proper API support it should start working. Until then, unfortunately, that task only works with VSTS.

Closing this issue since it's out of my control at the moment.
