由于您可以檢測到pom.xml兩次提交之間的更改列表：
git diff --name-status <commit1> <commit2>
（另見“ Git pull 后的細節變化”）
，您可以制作一個腳本，該腳本將為每個模塊執行一個mvn clean install.

我已經完成了一個可以滿足我要求的腳本。
該項目是一個 POM 項目，其中包含包含應用程序主要項目的子 POM 項目。我通過讓當前工作分支調用來實現了預期的結果git diff --name-status HEAD@{1} <current_branch>。
這得到了項目中已更改文件的列表，然后我將其拆分為一個數組。不幸的是，我無法讓拆分正常工作，因此數組被組織為更改類型，后跟文件路徑。
然后我檢查了字符串大小，跳過了單個字符串。下一步是將字符串拆分為一個數組，由 . 分隔/。如果根路徑檢查它是否存在于數組中，如果不存在則添加。
最后，遍歷根路徑數組并執行 maven 調用。
