當git repo中的子目錄更改時，在Jenkins中構建

Question

我有一個帶有n個目錄的倉庫：

.
├── .git
├── project_1
├── project_2
└── project_3

在jenkins中，我希望每個項目都有3個版本（因此我使用了稀疏簽出）。 但是，如果我改變了只project_1我想只建project_1 。 如何配置詹金斯做到這一點？

Answer 1

如果它在GUN / Linux機器上運行，則可以在jenkins中運行類似於以下腳本：

PROJECTX=$(git diff-tree --no-commit-id --name-only -r HEAD | cut -d"/" -f1 | sort | uniq) && \
if [ "$PROJECTX" == "project_1" ]; then
  # build project_1
elif [ "$PROJECTX" == "project_2" ]; then
  # build project_2
elif [ "$PROJECTX" == "project_3" ]; then
  # build project_3
fi

Answer 2

如果您將Stash用作git服務器，則可以使用Groovy來測試提交以運行特定模塊的路徑。

在您的工作中，選擇“准備運行環境”，然后將下面的腳本粘貼到“ Evaluated Groovy腳本”中。 腳本完成后，您可以使用環境布爾值測試每個模塊中是否有更改：

$ {project_1_CHANGED} == true->運行邏輯

$ {project_2_CHANGED} == true->運行邏輯

$ {project_3_CHANGED} == true->運行邏輯

如果項目無關，我也建議使用Multijob插件。
