lockfiles only work if pants.backend.python is activated #14876

Closed ryanking closed 2 years ago

Describe the bug

In a repo which does not use python (terraform & go) I had troubled getting lockfiles generated.

Unknown flag --resolve on global scope
Did you mean --level?
Use `./pants help` to get help.
11:57:54.70 [ERROR] Unknown flags --resolve on global scope

Use --print-stacktrace for more error details and/or -ldebug for more logs. 
See https://www.pantsbuild.org/v2.9/docs/troubleshooting for common issues.
Consider reaching out for help: https://www.pantsbuild.org/v2.9/docs/getting-help

Once i added pants.backend.python to backend_packages the command worked.

Pants version 2.9.0

OS Mac

What were you trying to generate lockfiles for? Pants does not generate lockfiles for Go or Terraform yet. When you don't have pants.backend.{python,java,scala} activated, then Pants should not be showing the generate-lockfiles goal with ./pants help goals.

I was trying to generate a lockfile for the terraform hcl2 parser (so that I could upgrade the library version).

@tdyas suggested ./pants generate-lockfiles --resolve=terraform-hcl2-parser to do that, which fails. I don't know if help was listing it or not.

Ahhh that makes sense. Thanks for filing this! So we need to register the Python generate-lockfiles rules for Terraform & I think Docker because they use PythonTool. Go does not need it.
