使用模块时go项目的工作目录在哪里？

Question

I am trying to download, make some tweaks and build a golang project from GitHub. The project's instructions are:

go get github.com/<vendor>/<projectName>
cd src/github.com/<vendor>/<projectName>
go build .

That used to work in the past — before enabling Go Modules.

Now I have GO111MODULE=on (go version go1.15.4 linux/amd64 ). When running the first command, go downloads the project as a module and all its dependencies.

But then there is no src/github.com/<vendor>/<projectName> folder anymore. Moreover, the is no folder named <projectName> anywhere in the system.

Instead, there is folder pkg/mod/github.com/<vendor> which contains the project folder with weird symbols in its name (exclamation marks etc.) and version identifiers.

How do I get the project folder available for making tweaks and builds?

Answer 1

As pointed by @Volker, good old git clone should be used.

It turns out that it should be used instead of go get github.com/<vendor>/<projectName> (no idea why the project vendor recommends that):

git clone git://github.com/<vendor>/<projectName>
cd <projectName>
go get ./...
# do tweaks here
go build .

If your goal is tweaks, the easiest way it use to use go mod vendor . https://golang.org/ref/mod#go-mod-vendor

The go mod vendor command constructs a directory named vendor in the main module's root directory that contains copies of all packages needed to support builds and tests of packages in the main module
