TFS 2015 vNext build fails with error Unable to perform the get operation because the file already exists locally

During our incremental builds, where the repository clean parameter is set to 'false'. Build fails intermittently during get source step with the following error: Unable to perform the get operation because the file already exists locally.

Is there a way to resolve the error without setting the repository clean parameter to true?

@Buck Hodges (Director of Engineering at Microsoft) has given the answer in this case:

The file is writable. When there's a writable file, get will not overwrite it unless the /overwrite option is used. However, you would need to figure out how the file is becoming writable. You may want to go back to the default option of creating a new workspace, running a build with verbose logs, and see what is making the file writable.

Build vnext agent (1.x) does not provide a way to control whether /overwrite is included. The new agent (2.x) does specify /overwrite every time in order to prevent writable files causing problems. The new agent will be the default in TFS "15" and in VS Team Services.
