   Error: Could not load plugin

   Plugin reinitialization required. Please run "terraform init".

   Plugins are external binaries that Terraform uses to access and manipulate
   resources. The configuration provided requires plugins which can't be located,
   don't satisfy the version constraints, or are otherwise incompatible.

   Terraform automatically discovers provider requirements from your
   configuration, including providers used in child modules. To see the
   requirements and constraints, run "terraform providers".

   Failed to instantiate provider
   "registry.terraform.io/hashicorp/confluent-cloud" to obtain schema: unknown
   provider "registry.terraform.io/hashicorp/confluent-cloud"

I am trying to migrate to terraform 13 but the plugin is not working with it. I don't have a proper provider development environment but I tried to update the go terraform dependency, built it, but still doesn't work. Can you take a look and provide a new version that works with terraform 13?

Thanks

@yottta I do not have such issues on my end with Terraform v0.13.2 :) please ensure that you have configured the provider in a 'new' way

terraform {
  required_providers {
    # https://github.com/Mongey/terraform-provider-confluentcloud
    confluentcloud = {
      source = "mongey/confluentcloud"
      version = "0.0.5"
    }

    # https://github.com/Mongey/terraform-provider-kafka
    kafka = {
      source  = "mongey/kafka"
      version = "0.2.10"
    }
  }
  required_version = "0.13.2"
}

and use it after all as:

locals {
  bootstrap_servers = [replace(confluentcloud_kafka_cluster.env0_test.bootstrap_servers, "SASL_SSL://", "")]
}

provider "confluentcloud" {
  username = var.confluent_username
  password = var.confluent_paswword
}

provider "kafka" {
  bootstrap_servers = local.bootstrap_servers

  tls_enabled    = true
  sasl_username  = confluentcloud_api_key.env0_test.key
  sasl_password  = confluentcloud_api_key.env0_test.secret
  sasl_mechanism = "plain"
}

Thanks @rjudin.

I tried it, and it works indeed. But this might be because the providers are fetched from the terraform registry, which were not before (cause were not pushed).

And for confluentcloud, I used a fork of it (I don't remember the reason now, but I'm more than sure that was a bug at some point), which is not published to registry, so I needed to use from a local file but for this the documentation on terraform 13 it's pretty foggy.

Anyway, thanks for this! I will close the issue for now.
