Issue/Introduction

CF CLI v7 Push failing with below error:

Error <buildpack> must be an existing admin buildpack or a valid git URI

This eventually fails the App staging with the below error:

BuildpackCompileFailed - App staging failed in the buildpack compile phase FAILED

Environment

Product Version: 2.11

Resolution

Cause

• This is a known issue with cf CLI v7 as per this git issue.
• Looks like the stack is over-ridden by the cf CLI, so if you don't mention -s in cf push, it'll take it as <blank> and throw this error

 

Workaround

• The workaround is to specify -s <stack> in cf push command, irrespective of the stack mentioned in the manifest.

 

Permanent Fix

• Upgrade to cf CLI version 7.3.0
