Azure Pipeline failed for maven app engine deploy - maven

Question

I have been trying to deploy my app engine app from azure pipeline now.
I was able to make mvn clean and package it but when i used mvn appengine:deploy it does throw this permission issue. I got through some common questions like this:
I cant init Google Cloud SDK on Ubuntu
and
gcloud components update permission denied
What I did, I added the script tag before my maven in yml file.
- script: |
sudo chown -R $USER /home/vsts/.config/gcloud/config_sentinel
- task: Maven#3
displayName: 'Maven api/pom.xml'
inputs:
mavenPomFile: 'api/pom.xml'
goals: 'clean package appengine:deploy'
But not sure what is the issue and which else permission i need to set my USER for pipeline is vsts here. Please let me know if i made any mistake so far.
Error log from the pipeline is below for reference:

Answer 1

As requested, posting my yaml file which may help few to solve the same problem.
Now I given the permission to the parent directory which is gcloud one, as I shown other directories were giving issue.
- script: |
sudo chown -R $USER:$USER /home/$USER/.config/gcloud/
- task: Maven#3
displayName: 'Maven api/pom.xml'
inputs:
mavenPomFile: 'api/pom.xml'
goals: 'clean package appengine:deploy'
I uses $USER to make it for all. As I used Azure maintained Agent my pipeline user was vsts which picked up automatically. And would help others irrespective of their user.
if any more help required let me know thanks.
