azure-pipelines-agent: Cache persist doesn't work on server 2012 R2 or 2016 (I assume) because it doesn't inclued tar

Having issue with Tasks?

Since this is the embedded cache task I believe this belongs here.

Agent Version and Platform

Version of your agent? 2.160 on prem

OS of the machine running the agent? Windows 2012 R2

Azure DevOps Type and Version

dev.azure.com

https://dev.azure.com/gmollc

What’s not working?

CacheBeta@1 isn’t saving the cache because tar isn’t included in 2012 R2.

Let’s make this error clearer that TAR needs to be on the path

Hi @johnterickson , @b-barthel already has a PR out for “Can we add C:\Program Files\Git\usr\bin to the search path for tar on Windows?”

Docs are live: https://docs.microsoft.com/en-us/azure/devops/pipelines/caching/index?view=azure-devops#required-software-on-self-hosted-agent

Thanks @fadnavistanmay!

@fadnavistanmay Can we add C:\Program Files\Git\usr\bin to the search path for tar on Windows?

johnterickson on Jan 10, 2020

Hi @garfbradaz , sorry for the delay in documentation update. We have a PR out, it looks like it haven’t merged yet. I’ll follow up to get the docs updated.

@fadnavistanmay I was able to reproduce this on my public azure devops. It really is as simple as installing the agent on a 2012 r2 server. I just created one in azure: https://dev.azure.com/mike-barry/Demo2012Issue/_build/results?buildId=420&view=results

If you need additional access please let me know
