I am using lsp-mode with Gopls as my coding environment. But I have one file with

// +build tagthis

at beginning of the file. Then my emacs lsp-mode cannot work well in this file. How can I change custom of go build flag for letting lsp-mode works well in this file?

I have make

   lsp-go-build-flags (vector "tagthis")

in my configuration. But it doesn't work.

I figure out the solution. Just change lsp-go-env with

   lsp-go-env '((GOFLAGS . "-tags=tagthis"))

make it works.
