Tar Issues - Error opening archive and cleaning up compressor on Windows Image

[Cdoherty95]

We are seeing an issue when using the Restore and save cache task on a Microsoft Hosted Agent running a Windows image. The task runs just fine, with the same configuration, when we use a Linux image. We are trying to cache npm packages for our angular application but cannot seem to figure out this tar issue while running on a Windows image. Issue #35 is the same error we are getting but the issue has been closed for a few months now.

The error we get when restoring is: tar: Error opening archive: Failed to open '/D/a/1/s/tmp_cache/aaa579713b25a5a1b4e37b99c571beadb0b1ec3592e007eb503ac631.tar.gz'

The error we get when saving is: Issue creating tarball: tar: Failed to clean up compressor

Windows Image: windows-2019
Key file: RepositoryRoot\AngularApplication\package-lock.json
Target folder: RepositoryRoot\AngularApplication\node_modules

Running on Image: ubuntu-20.04 with the same Key file and Target folder the Restore and save cache task runs as expected.

I think the error when restoring might be a path issue. On both images, it tries to use a Linux path /D/. On the Windows image, I think it needs to be D:/.

Please let me know if more details are needed. Any help would be appreciated!

@Cdoherty95 sorry to hear that you've been running into this issue. Have you tried to use the Azure DevOp's built in Pipeline Caching tasks which are the successor to these tasks? The tasks in this repo inspired the official tasks but the tasks in this repo are not actively maintained.

Thanks for the reply. I was really hoping to use this task but I will give the Pipeline Caching task a shot
