azure-pipelines-tasks: Download Pipeline Artifact - wrong match pattern

Type: bug

Enter Task Name: Download Pipeline Artifact uses wrong match pattern

Environment

• Server - Azure Pipelines
• Agent - Hosted

Issue Description

When the build pipeline produces multiple artifacts and we want to choose just a few of them in the release pipeline, the artifact is not downloaded because of a wrong file match pattern. In the sample below out of 3 artifacts we chose 2: IPA and dSYM. Observe how the minimatch pattern tries to filter files which are ALREADY filtered when downloading IPA artifact from the build pipeline:

Here’s an example when ALL artifacts are selected for download. Note the minimatch pattern correctly assumes ** pattern here:
