There are two warnings in the output, the first is this issue, the second looks like #827.

The issue is present for versions 1.21.0, 1.20.1 and 1.20.0. It is not present for version 1.19.1.

Hi, thank you for report.

Is it only for go1.14?

Probably we should rebuild golangci-lint with go1.14 after the release, but I'm not sure that it will help.

I was able to reproduce with Go 1.14.x and latest master. The fix is to update x/tools to a more recent version.

Be careful, if you update to a more recent version of x/tools, it causes some issues with the govet linter.

golangci-lint/pkg/golinters/govet.go

Lines 80 to 83 in cb2f8ba

	if a.ResultType != nil {
	// Skipping internal analyzers.
	continue
	}

This condition matches for some analyzers, such as printf, because they changed it in x/tools "recently".
If you configure the key linters-settings.govet.settings.printf in the config file, it will throw an error about unknown/invalid key.

This error occurred for me, because I was not able to run golangci-lint with Go 1.14.
So I decided to install it with go get.
I was working fine with v1.21.0, but since v1.22.0 it's broken. (due to the x/tools update)
I learned recently that it's not recommended to install golangci-lint with go get.
BTW, go get is used by vscode-go, so it's also broken now.

[tpounds]

@pierrre Thanks for the follow up. We actually haven't updated x/tools in any releases since we are using an explicit replace directive in the go.mod. This is not carried transitively when using go get in a downstream project. Can confirm this on your end by copying the directive into your own project's go.mod file?

[pierrre]

by copying the directive into your own project's go.mod file?

I can't do it, because I'm not using it in a project.
I'm installing it "globally" on my system.

But I'm sure that the replace is the cause.
