For one of our build definitions (Scheduled, from Monday to Friday, at 2:00 AM) we receive the following error message every night: One or more of the steps defined in the build does not have an associated task definition Unfortunately no log is written. Manually queuing a new build works most of the time. The error occurs only for builds scheduled during the night. I found a link: https://github.com/Microsoft/vsts-tasks/issues/1170 but that link was not very helpful. They mailed to each other and MS says they solved some caching issues. Not something we could do by our own. So has someone the same issue and found a solution? Additional information: We are using: Visual Studio 2015 Update 3 Visual Studio TFS 2015 we are using 3 build servers, but before it starts on any of the build servers, it is already crashed. There is no log which can be downloaded: see picture ("Download all logs as zip" can't be clicked) Only message we receive is: "One or more of the steps defined in the build does not have an associated task definition." Source Version of failed builds is always "T". Source Version of successful builds is a number (int) -> most recent build has highest number. Update 20160815: We are using TFS 2015 update 2. Our architect has planned a meeting, to check if we can update to update 3 , maybe the caching fixes from MS will do the trick.

TFS2015 build: "One or more of the steps defined in the build does not have an associated task definition"

Unfortunately no log is written. Manually queuing a new build works most of the time. The error occurs only for builds scheduled during the night.

Additional information: We are using:

We have TFS 2015u3 with the same issues. We use scheduled builds and all builds (on 2 build agents) are crashing. As suggested in the GitHub thread I disabled SSH in the TFS Console. It works now again.

The source version "T" means the build agent are running tf get /version:T command which will get the latest version of your source code during build process. Please refer to tf get command for details:

Specifies the maximum version, or the minimum and the maximum versions, to display in the history data. The default is /version:T (the latest version).

According to your screen shot, the phenomenon looks like the build is not picked up by any agent. Another possibility is the build process hangs when obtaining the latest version.

You can set up a daily scheduled build to observe if there is such a phenomenon, and you can also go to the "_diag" folder in build agent folder and event view to check if there are any related the logs.
