"Unknown Validator matches" error trying to run "provision"

[ryanwalls]

Not sure if the format of the s3 bucket name is the cause... but getting this error with a bucket name like "3dsim-infrastructure-configuration".

[ryanwalls]

Correction... happens with any bucket name I try. Trying to run the "hello world" example from the readme.

This also does not work threedsimlambda.

When I run with debug flag, I get this output:

Ryans-MacBook-Pro:payment-processor ryan$ go run main.go provision -s threedsimlambda --noop -l debug

Just realized there was a closed issue for this #11

No worries - thanks for the details. I'll take a look.

HI @ryanwalls - this incorrect error is coming from https://github.com/asaskevich/govalidator. Do you have the latest version of this package? I go getd both that and https://github.com/spf13/cobra and am unable to reproduce even with the short flags. I'll keep investigating & appreciate the details.

@mweagle I use https://github.com/Masterminds/glide to manage my dependencies. It pulls in the latest "release" versions of the libraries for transitive dependencies... so it pulled in the v4 tag (commit 7664702). But apparently that release version is causing the problem, because when I updated to the latest commit, the problem went away.

Perhaps one change you could make would be to use Glide or Godeps to explicitly list sparta's transitive dependencies?

[mweagle]

Good to hear that resolves the issue.

Agreed - I've been deliberately holding off committing to a package manager, but will have to reconsider that. Filed as: https://github.com/mweagle/Sparta/issues/18
