I finally understood. The GOPATH definition is not relevant here. It is the presence of the go.mod file that determines if the module mode is in application. With go1.13, without go.mod file, the old GOPATH mode is in application.
The go.mod file is create by "go mod init [package name]". When present, a "go get" will download and install all dependencies. Sorry for the noise.
