I'm sorry, you cannot place any Go source code at the root of $GOPATH/src
because it implies the import path of that package would be blank.

What version of Go are you using (go version)?
1.8
What operating system and processor architecture are you using (go env)?
amd64
What did you do?
I have a main.go just in $GOPATH/src/，any other works well for this
project. But if I import something in this main.go and put the packages in
vendor directory, go build will report an error.
If possible, provide a recipe for reproducing the error.
A complete runnable program is good.
A link on play.golang.org is best.
What did you expect to see?
vendoring should work for the main package in $GOPATH/src
What did you see instead?

You can put Go source code in $GOPATH/src, but only because you can put Go source code in any directory, even outside $GOPATH. For the purposes of the Go command, code in $GOPATH/src is considered not part of the usual $GOPATH processing - only subdirectories of $GOPATH/src are subject to that. (As Dave says, a distinguishing characteristic is that in $GOPATH/src there is no clear import path, just like anywhere else outside $GOPATH.) That's why vendor doesn't work, and why vendor isn't going to work. If you do drop a source file in $GOPATH/src and run 'go build', the resulting binary is named 'src', because the heuristic to use the name of the containing directory still applies. Unless you are actually building a program named 'src', you have to create a subdirectory to set the name properly. You also have to create a subdirectory to pick up vendored code. Sorry. |
