The dependencies are introduced through the following chains: (A) /host/spi-builder-workspace->github.com/pvzig/skwebapi->github.com/slackkit/skcore (B) /host/spi-builder-workspace->github.com/pvzig/skcore. If there are multiple chains that lead to the same dependency, only the first chain is shown here. To see all chains use debug output option.
