Install HWC Buildpack Errand Fails

Products

• VMware Tanzu Application Service for VMs

Issue/Introduction

Symptoms:
In PASW 2.2 and 2.1, the post-deploy 'Install HWC Buildpack' errand fails due to the '-s' flag included in the 'create-buildpack' and 'update-buildpack' command. 

The error shown by the errand is as follows:

Use 'cf.exe target' to view or set your target org and space. 
FAILED 
Stderr 

Option '-s' requires CF API version 2.114.0 or higher. Your target is 2.112.0. 1 errand(s) 

Errand 'install-hwc-buildpack' completed with error (exit code 1) 
Exit code 1

Environment

Cause

The '-s' flag of the 'cf create-buildpack' and 'cf update-buildpack' command is used to associate a stack with the buildpack, which is a new feature in PAS 2.3. The CF API in PAS 2.2 and 2.1 does not recognise this flag and the create/update command fails.

Resolution

Install the release of the PASW tile which has the HWC buildpack containing the fix for this issue (hwc-buildpack v3.0.3).
hwc-buildpack v3.0.3 is included with PASW 2.3.2
