When I open my Goland project, the following command is run:
/usr/local/Cellar/go/1.14/libexec/bin/go list -m -json all #gosetup
Its output is the following error:
go list -m: can't compute 'all' using the vendor directory
(Use -mod=mod or -mod=readonly to bypass.)
Goland cannot resolve the packages I'm importing. When I build and run the project from the command line, it works fine.
My project is structured as follows:
app/
bin/
pkg/
src/
app/
cmd/
vendor/
go.mod
My GOROOT is /usr/local/Cellar/go/1.14/libexec and my GOPATH is app/.
In Goland settings, under Go/GOPATH have checked the boxes for "Use GOPATH that's defined in system environment" and "Index entire GOPATH".
Under Go/Go Modules (vgo), I have checked "Enable Go Modules (vgo) integration" and "Vendoring mode"
I have just noticed when I change the GOPATH to /Users/myname/sdk/go1.13.4, the problem is solved. Could this be an issue with Homebrew or a change introduced with go 1.14 that I am not aware of?
I'm being exhaustive when describing the issue because I'm unfamiliar with Go and might be missing something obvious. Thanks!
This is a known problem with Go Modules and vendoring support due to tooling change in Go 1.14.
As such, please try the EAP version of the IDE, https://jetbrains.com/go/nextversion, which contains a fix for this.
We are tracking this under https://youtrack.jetbrains.com/issue/GO-8855 and thinking about backporting this to the 2019.3 release cycle.
