如何在dep中使用本地src覆盖供应商软件包（用于本地开发）

Pseudo project setup:

• $GOPATH/src/github.com/foo/common-libs
• $GOPATH/src/github.com/foo/my-project (has a dependency on common-libs managed by dep, copy in /vendor directory

Can't find a way to edit common-libs locally (i.e. in /src) and have those changes immediately reflected in my-project. The project /vendor file always has priority over that in $GOPATH.

Instead every time I need to push the common-libs changes to Github then run dep ensure -update in my-project -- which is really slow and annoying.

Tried (unsuccessfully):

1. Ignoring local /vendor in Gopkg.toml using ignored = ["github.com/foo/common-libs*"], but throws a compilation error: cannot use &amount (type *"github.com/foo/my-project/vendor/github.com/shopspring/decimal".Decimal) as type *"github.com/foo/common-libs/vendor/github.com/shopspring/decimal".Decimal in field value)
2. Manually deleting common-libs from the /vendor directory of my-project (temporarily) -- but this leads to the same compilation error as #1 (and is annoying because running dep ensure adds the deleted folder back to the vendor folder).
3. Manually editing common-libs in /vendor (temporarily), which works -- but I lose static code analysis and I have to copy the changes to the actual common-libs projects afterwards.

Any help appreciated! Thanks.
