Azure-pipelines-tasks: %25 detected in ##vso command in some Tasks

[ElvenSpellmaker]

Note

##[warning]%25 detected in ##vso command. In March 2021, the agent command parser will be updated to unescape this to %. To opt out of this behavior, set a job level variable DECODE_PERCENTS to false. Setting to true will force this behavior immediately. More information can be found at https://github.com/microsoft/azure-pipelines-agent/blob/master/docs/design/percentEncoding.md

Question, Bug, or Feature?
Bug

Enter Task Name:

• AzureResourceManagerTemplateDeployment@3
• FileTransform@2
  EDIT:
• Docker@2
• PublishTestResults@2
• CopyFile@2
• AzureRmWebAppDeployment@3
• AzureCli@2 (with % in parameter or inline script)
• AzureResourceGroupDeployment@2

Issue Description

As of today we've been getting warnings in Template deploys and in FileTransforms relating to the % encoding feature. The tasks seem to be emitting ##vso commands which contain these characters and so clutter our build logs with warnings.

I have the exact same issue on Docker@2.
It started only a few hours ago

jobs:
  - job: BuildAndPush
    displayName: Build and Push Image
    pool:
      vmImage: ubuntu-16.04
     steps:

      - task: Docker@2
         inputs:
         command: login
         containerRegistry: docker-service-connection

      - task: Docker@2
         displayName: Build and push image
         inputs:
          command: buildAndPush
          containerRegistry: docker-service-connection
          repository: ${{ parameters.imageRepository }}
          dockerfile: ${{ parameters.dockerfilePath }}
          tags: |
            ${{ parameters.tag1 }}
            ${{ parameters.tag2 }}

output:

##[warning]%25 detected in ##vso command. In March 2021, the agent command parser will be updated to unescape this 
to %. To opt out of this behavior, set a job level variable DECODE_PERCENTS to false. Setting to true will force this behavior

I have the same issue. Also, release is not triggered after a new build is available. I am sure it was working

[bahadir-be]

Same issue!!

We have started hitting this with the PublishTestResults task as well:

These are coming from tasks that are build in this repo and so it seems like we need to get these all updated before we start blasting everyone's builds with these warnings.

We are seeing this warning during our build when we push a Docker image to a container registry

Bumping, we get this with when using:

[PetrPospisil]

maybe related to this?
microsoft/azure-pipelines-agent#3204

it also happens to us
AzureCli@2 (with % in parameter or inline script)
AzureRmWebAppDeployment@3 (did not try to update to @4 yet)

[mmajcica]

Same here.

[ElvenSpellmaker]

Which commands? I'm trying to keep an updated list in my issue

Which commands? I'm trying to keep an updated list in my issue

I get it by using AzureResourceGroupDeployment@2
Not sure what commands internally are used.

I see this too. But this is happening when the nuget security analysis job runs (This is injected by policy. So i do not control it).
