can we do helm init before build?

[ryandawsonuk]

There are two 'helm dep build' in the makefiles e.g.:

https://github.com/jenkins-x/draft-packs/blob/master/packs/maven/charts/Makefile#L9
https://github.com/jenkins-x/draft-packs/blob/master/packs/maven/charts/Makefile#L26

When I add a requirements.yaml and a chart in it (e.g. postgres) then I get:

"Couldn't load repositories file ... you might need to run helm init"

I hit this in https://github.com/ryandawsonuk/example-runtime-bundle/tree/develop/charts/example-runtime-bundle (see the requirements.yaml and Makefile there)
