Use golangci-lint v2 to lint with v1 config file?

[fredrikaverpil]

Is it possible?

I have:

• golangci-lint v2
• .golangci.yml (v1)

I am getting:

Error: can't load config: unsupported version of the configuration: "" See https://golangci-lint.run/product/migration-guide for migration instructions
Failed executing command with error: can't load config: unsupported version of the configuration: "" See https://golangci-lint.run/product/migration-guide for migration instructions

I'm then adding version: "1" at the top of the config file, but then I get:

Error: can't load config: unsupported version of the configuration: "1" See https://golangci-lint.run/product/migration-guide for migration instructions
Failed executing command with error: can't load config: unsupported version of the configuration: "1" See https://golangci-lint.run/product/migration-guide for migration instructions

Is it not possible to have golangci-lint v2 installed to lint different projects, using different versions of the config yaml file?

No you need a v2 config for v2 of golangci-lint. The reason is simply that the code to parse v1 configuration files isn't in the v2 binary. On top of that, some of the v1 configuration and way of working was changed or removed in v2.

However your v1 project can easily be upgraded with golangci-lint migrate, see https://golangci-lint.run/product/migration-guide/.

If you want to use different versions of golangci-lint in different projects you need multiple versions of golangci-lint installed.

I wrote gclv to easily install multiple versions and switch between them.
