Packer: Builds finished but no artifacts were created when variable blocks are Incuded

[TejaswiniTharigopula2295]

Packer Version 1.6.1

I'm trying to include variable blocks with json format

foo.pkr.json

{
"variable": {
"project_id": {
"type": "string",
"description": "Project ID in GCP",
"default": ""
}
}
}

foo.pkrvars.json

{
"project_id": "xxx"
}

when I run packer build -var-file="foo.pkrvars.json" .

getting output as

==> Builds finished but no artifacts were created.

Hey there! So, I guess you should be using an HCL2 template instead of JSON in order to use the foo.pkrvars.json, the command line your using and to define the project_id variable as you did.

I suggest you create a variables.pkr.hcl file with:

variable "project_id" { 
  type    = string   
  description = "Project ID in GCP"
  default = ""
}

And upgrade your JSON template to HCL2 using the hcl2_upgrade command.

To keep working with JSON, you can the template with the correct form of the variables block like:

{
    "variables": {
           "project_id": ""
      }
}

and build the VM with the command: packer build -var 'project_id=xxx' foo.json

I suggest checking out the docs about user variables in JSON templates HERE and also the one about user variables in HCL2 HERE.

I'll close the issue but feel free to follow up with questions if you need some help.
