Answer 1

Using absolute path through built-in release variable instead.
For example, System.DefaultWorkingDirectory ($(System.DefaultWorkingDirectory)): The directory to which artifacts are downloaded during deployment of a release. The directory is cleared before every deployment if it requires artifacts to be downloaded to the agent. Same as Agent.ReleaseDirectory and System.ArtifactsDirectory.
