Azure Pipeline- Copy files from one Repo to another Repo using YAML - azure

Question

There is a folder in one of the repositories (Source Repo) that I like to copy to another repository (Destination Repo) using Azure Pipeline (as they needed to be in sync)
so far I can Copy a folder in the same repository using:
- task: CopyFiles#2
inputs:
SourceFolder: '$(Build.Repository.LocalPath)\MyFolder\'
Contents: |
**
!**\obj\**
!**\bin\**
TargetFolder: '$(Build.Repository.LocalPath)\DestFolder'
flattenFolders: false
CleanTargetFolder: true
OverWrite: true
preserveTimestamp: true
this is how I connect to another repository:
resources:
repositories:
- repository: SourceRepo
type: git
name: MyCollection/SourceRepo
but I don't know how to get files from the source repo and place them in the Destination Repo

Answer 1

after a lot of searching, this is the answer:
resources:
repositories:
- repository: SourceRepo
type: git
name: MyCollection/SourceRepo
steps:
- checkout: SourceRepo
clean: true
- checkout: self
persistCredentials: true
clean: true
- task: DotNetCoreCLI#2
displayName: "restore DestRepo"
inputs:
command: 'restore'
projects: '$(Build.Repository.LocalPath)/DestRepo/**/*.csproj'
feedsToUse: 'select'
- task: DotNetCoreCLI#2
displayName: "build DestRepo"
inputs:
command: 'build'
projects: '$(Build.Repository.LocalPath)/DestRepo/DestRepo/**/*.csproj'
configuration: Release
# configurations for using git command
- task: CmdLine#2
inputs:
script: |
cd $(Agent.HomeDirectory)\externals\git\cmd
git config --global user.email ""
git config --global user.name "$(Build.RequestedFor)"
- task: CmdLine#2
displayName: checkout
inputs:
script: |
git -C RootRep checkout $(Build.SourceBranchName)
- task: CmdLine#2
displayName: pull
inputs:
script: |
git -C DestRepo pull
- task: CopyFiles#2
inputs:
SourceFolder: '$(Build.Repository.LocalPath)\SourceRepo\SourceFolder'
Contents: |
**
!**\obj\**
!**\bin\**
TargetFolder: '$(Build.Repository.LocalPath)\DestRepo\DestFolder'
flattenFolders: false
CleanTargetFolder: true
OverWrite: true
# preserveTimestamp: true
- task: CmdLine#2
displayName: add
inputs:
script: |
git -C DestRepo add --all
- task: CmdLine#2
displayName: commit
continueOnError: true
inputs:
script: |
git -C DestRepo commit -m "Azure Pipeline Repository Integration"
- task: CmdLine#2
displayName: push
inputs:
script: |
git -C DestRepo push -u origin $(Build.SourceBranchName)

Answer 2

I was trying to find some solution related to this problem, but instead of using a copy file task, I found a better way and we can use any number of repositories are resources in the build pipeline and we don't need to check out all these.
This is how my build pipeline looks like.
As you can see I have used two variables
$(System.AccessToken), this variable is available in Azure DevOps aka PAT(Personal Access Token)
$(Build.Repository.Uri) URL of the repository (this could be the URL of any repo in resources).
