To work with a local dependent module, check out that module into this directory, and put the local replace into the main go.mod.

Example:

cd local
git clone  [email protected]:edwarnicke/sdk.git
cd sdk
git remote add upstream [email protected]:networkservicemesh/sdk.git
cd ../..

And then edit the go.mod file utilize a replace:

module github.com/networkservicemesh/cmd-forwarder-vpp

go 1.13

require (
...
)

replace github.com/networkservicemesh/sdk => ./local/sdk
