helm: "helm dep build" fails if requirements.yaml contains local dependencies and remote one

Hello

I have a chart that contains two dependencies, one is located in our internal helm registry, one is copied into the charts sub-directory. I can either use “helm dep build” with only the one from the registry or the local one, but not in combination:

$ tree .
|-- Chart.yaml
|-- README.md
|-- charts
|   `-- oraclepdb
|       |-- Chart.yaml
|       `-- templates
|           `-- oraclepdb.yaml
|-- requirements.yaml
|-- templates
|   |-- _helpers.tpl
|   |-- deployment.yaml
|   |-- ingress.yaml
|   |-- secrets.yaml
|   `-- svc.yaml
`-- values.yaml

The helm registry is added:

$ helm repo list
NAME    URL
stable  https://kubernetes-charts.storage.googleapis.com
local   http://127.0.0.1:8879/charts
mobi    https://git.bitbucket.server/projects/K8S/repos/charts/raw

Using this requirements yaml:

$ more requirements.yaml
dependencies:
  - name: mobi-postgresql
    version: 1.0.1
    repository: "@mobi"
    alias: postgresql
  - name: oraclepdb
    version: 0.0.1

and then “helm dep list”

NAME            VERSION REPOSITORY      STATUS
mobi-postgresql 1.0.1   @mobi           missing
oraclepdb       0.0.1                   unpacked

then trying “helm dep update” fails:

Error: no repository definition for . Please add them via 'helm repo add'
Note that repositories must be URLs or aliases. For example, to refer to the stable
repository, use "https://kubernetes-charts.storage.googleapis.com/" or "@stable" instead of
"stable". Don't forget to add the repo, too ('helm repo add').

for some reason the sub-chart in charts is no longer a local one.

Just using this requirements.yaml and running “helm dep update” works:

dependencies:
  - name: mobi-postgresql
    version: 1.0.1
    repository: "@mobi"
    alias: postgresql

It also works if both sub-charts are copied and extracted already.

I tried pointing to the file using this requirements.yaml:

dependencies:
  - name: mobi-postgresql
    version: 1.0.1
    repository: "@mobi"
    alias: postgresql
  - name: oraclepdb
    version: 0.0.1
    repository: "file://./charts/"

$ helm dep list
NAME            VERSION REPOSITORY              STATUS
mobi-postgresql 1.0.1   @mobi                   missing
oraclepdb       0.0.1   file://./charts/        unpacked

$ helm dep build

Deleting newly downloaded charts, restoring pre-update state

this does not download the mobi-postgresql file anymore.

So currently I can only use remote charts or both within the charts sub-directory. But mixing them havong one from remote and one unpacked (in case some chart does not yet offer some values, so we temporarly copy them) does somehow not work.

using helm 2.8.2 on windows.

Is there a workaround?
