為了像另一個專案開發人員已經完成的那樣設定專案，我這樣做了
- 克隆根專案 repo 并切換/簽出 dev 檔案夾。它在相應的檔案夾中包含一些名為 core 和 deps 的專案。
build.sbt 這個根目錄包含一些 sbt 專案中的提及：
lazy val industry = (project in file("industry"))
它沒有指向根檔案夾中的實際檔案夾
- 創建
industry檔案夾， cd 到它，再次簽出專案并切換/簽出到特定分支（例如，industry-dev）
所以現在提到的專案檔案夾有專案本身，它托管build.sbt了相應檔案夾中存在的自己和其他員工。我們必須以這種方式設定它，就像industry-dev基于來自的類一樣dev，它們作為核心類作業，我們需要同時觀察它們，而不是將單個專案從一個分支切換到另一個分支
在根檔案夾中嘗試執行
sbt 核心/清潔
我收到以下訊息的錯誤：

You can make this conversion explicit by writing `environmentArtifactSettings _` or `environmentArtifactSettings(_,_)` instead of `environmentArtifactSettings`.

那里的核心問題是什么？
uj5u.com熱心網友回復：
這個例外的原因是誤用了分支，每個分支都包含預期的 build.sbt。事實上，子檔案夾分支與 roo 相同，因此子專案 build.sbt 實際上與根專案 build.sbt 相同
因此，如果您遇到這種情況，請檢查您所期望的子專案的代碼。
