Useless message: "FATAL: Found legacy version file 'main.tf' with unsupported required version constraint expression"

[mjreed-wbd]

I appreciate that the plugin tries to determine the version to run based on the terraform code, but if it's not going to parse constraints that are valid to TF, that's no help.

It only displays the message when I don't have a "local" or "shell" version configured via asdf itself, but I do have one selected globally. And it's clearly not a "FATAL" condition, since it proceeds to run that version after printing the message out.

Would rather just get rid of the message.

You can suppress it by changing the configuration file as follows.

~/.asdfrc

legacy_version_file = no

Unfortunately I have that setting enabled to work with https://github.com/asdf-vm/asdf-nodejs

Would it be possible to create a way to disable that message? If I deployed this across my teams, it would cause some support calls from confused developers.

An alternative is to use rtx with a configuration file that looks like this

# ~/.config/rtx/config.toml
[settings]
legacy_version_file_disable_tools = ["terraform"]

to selectively disable this for Terraform.

Update (2025-01-14): I bumped into this issue again and found my own answer (🤦🏻). Things have moved along. rtx has become mise. A configuration snippet that works for me is now as follows.

# ~/.config/mise/config.toml
[settings]
legacy_version_file = true

[bllfrnch]

legacy_version_file is a name that's leftover from the asdf days; Mise has since begun calling "legacy version files" "idiomatic version files" (docs here). We were able to solve the problem once and for all by adding this to our Terraform-specific .mise.toml (though you could add it to your mise config like @adamroyjones suggests, too):

[settings]
idiomatic_version_file_disable_tools = ['terraform']
