Cargo: 貨物がプライベートgitlabリポジトリコードを取得し、git-credentialsストアで失敗しました

問題

Cargoがプライベートgitlabリポジトリコードを取得できませんでした。git-credentialsが機能しません。cargo.tomlにユーザー名/パスワードを書き込んでも問題ありません。

_git-資格情報が機能しない_

$ cat ~/.gitconfig
[credential]
        helper = store

$ cat ~/.git-credentials

$ cat Cargo.toml
[package]
name = "xxxxx"
version = "0.1.0"
edition = "2018"

[dependencies]
l5 = {git = "http://git.code.oa.com/birdio/l5-rs", branch = "master"}
