Couldn't load r.yml

[achuu126]

What version of Cloud Foundry and CF CLI are you using? (i.e. What is the output of running cf curl /v2/info && cf version?

What version of the buildpack you are using?

1.0.10

If you were attempting to accomplish a task, what was it you were attempting to do?

Trying to install R 3.6.0 while deploy my java api that calls R scripts.

What did you expect to happen?

Calling r-buildpack to install r 3.6.0

What was the actual behavior?

Got an error message

@achuu126 do you have a sample app we can test this out on? What stack are you running on? It sounds like you're using a multi-buildpack with R and Java - if so can you share your Java buildpack version too?

I have observed this error as well; adding an empty r.yml resolved the issue.

I'm not a Go programmer, but glancing at the relevant code, it appears that an r.yml may currently be effectively required?

r-buildpack/src/r/supply/supply.go
