May 20, 2016 To do so I use a copy task from CurrentBuild to LastBuild and skip changes. This works fine until here. I take the Output CopiedFiles as SourceFile of a second copy task to the Delta folder. My problem is the Output CopiedFiles returns ITaskItems with filename only, without the file path. C: Test C: Test CurrentBuild C: Test Delta.

Use this task to copy files from a source folder to a target folder using match patterns.

In Microsoft Team Foundation Server (TFS) 2018 and previous versions,build and release pipelines are called definitions,runs are called builds,service connections are called service endpoints,stages are called environments,and jobs are called phases.
Demands
None
Arguments
Argument | Description |
---|---|
SourceFolder Source Folder | (Optional) Folder that contains the files you want to copy. If you leave it empty, the copying is done from the root folder of the repo (same as if you had specified $(Build.SourcesDirectory) ). If your build produces artifacts outside of the sources directory, specify $(Agent.BuildDirectory) to copy files from the directory created for the pipeline. |
Contents Contents | (Required) File paths to include as part of the copy. Supports multiple lines of match patterns. More Information. For example:
|
TargetFolder Target Folder | (Required) Target folder or UNC path files will copy to. You can use variables. Example: $(build.artifactstagingdirectory) |
CleanTargetFolder Clean Target Folder | (Optional) Delete all existing files in target folder before copy Default value: false |
OverWrite Overwrite | (Optional) Replace existing files in target folder Default value: false |
flattenFolders Flatten Folders | (Optional) Flatten the folder structure and copy all files into the specified target folder Default value: false |
preserveTimestamp Preserve Target Timestamp | (Optional) Using the original source file, preserve the target file timestamp. Default value: false |
Notes
If no files are matched, the task will still report success.If a matched file already exists in the target, the task will report failure unless Overwrite is set to true.
Usage
A typical pattern for using this task is:
- Build something
- Copy build outputs to a staging directory
- Publish staged artifacts
For example:
Examples
Copy executables and a readme file
Goal
You want to copy just the readme and the files needed to run this C# console app:

Q & A
Where can I learn more about file matching patterns?
How do I use this task to publish artifacts?
See Artifacts in Azure Pipelines.
Q: I'm having problems. How can I troubleshoot them?
A: Try this:
- On the variables tab, add
system.debug
and set it totrue
. Select to allow at queue time. - In the explorer tab, view your completed build and click the build step to view its output.
The control options arguments described above can also be useful when you're trying to isolate a problem.
Q: How do variables work? What variables are available for me to use in the arguments?
A:
$(Build.SourcesDirectory)
and $(Agent.BuildDirectory)
are just a few of the variables you can use.Variables are available in expressions as well as scripts; see variables to learn more about how to use them.There are some predefined build and release variables you can also rely on.Do I need an agent?
You need at least one agent to run your build or release.
I'm having problems. How can I troubleshoot them?
See Troubleshoot Build and Release.
I can't select a default agent pool and I can't queue my build or release. How do I fix this?
See Agent pools.

I use TFS on-premises and I don't see some of these features. Why not?
Some of these features are available only onAzure Pipelinesand not yet available on-premises. Some features are available on-premises if you haveupgraded to the latest version of TFS.
Ah, copying a file — something so simple, it happens all the time. Copy this file there; copy that file here. But what exactly takes place when you copy a file? You actually create a new file, and fill it with the same contents as the original file. And how do you do that?
Well, it sounds like you have to read each and every byte from the first file, and write it to the second. Big-time yuck.
But to make matters worse, copying a file means you have to make sure that you copy it exactly the same, that you don’t accidentally tack an extra 0 or two at the end of the file, or an extra carriage return or linefeed at the end of the file (which could happen when you copy a text file).
When all is done, the two files should be identical — not only contain the same information, but also be the same size.
And on top of all that, most good copy routines do even more! They give the new file a date that matches the date of the original file, and they will set all the attributes — including, say, read-only if the original is a read-only file. (If the file is read-only, then maybe you shouldn’t be able to copy it in the first place. . ..)
Suddenly copying a file doesn’t sound so easy after all!
If you’re programming in Windows, you’re in luck! As long as you’re not using the ancient Windows 3.1, you get a CopyFile function! To get ready to use it, you include the line #include <windows.h> in your application. Then here’s all you have to do:
This copies from c:/dog.txt to c:/dog2.txt. But notice the final parameter: It’s the word TRUE in all capitals. What’s that? That’s a preprocessor macro defined somewhere in the bowels of the Windows header files.
You have to use either TRUE or FALSE when calling any of the Windows functions. That’s because in the old days of C, when the early versions of Windows were invented, no bool type existed. Those resourceful people of the late 20th century had to define their own TRUE and FALSE as integers (usually either 1 and 0, respectively, or 0 and 1, respectively).
And by the way, that final parameter in CopyFile tells the function what to do if the file you’re copying to already exists: TRUE means don’t overwrite the existing file; just abort. FALSE means overwrite it.
