Github Actions：你指定的目標需要一個項目來執行但是這個目錄下沒有POM

Question

我正在嘗試使用 Java 11 在 Azure App Service 中托管我的 Spring Boot Web 應用程序，當我將它部署到 github 操作時，為了托管它，它給了我以下信息：

Run mvn clean install
[INFO] Scanning for projects...

就在這里： （/home/runner/work/deskmate/deskmate）這不是我的任何目錄。 我的 pom.xml 與我的項目在同一個目錄中，在根級別。

pom.xml 本身：

問題：如何將 Github Actions 或 Azure App Service 指向正確的 pom.xml 路徑？ 我在哪里做（PowerShell，IntelliJ 終端？在 Github Actions 的某個地方？）

Answer 1

我找到了一個簡單的解決方案！ 只需使用 GitHub Actions 中的 Checkout 步驟即可。

在你的步驟中添加這個：

- name: Standard Checkout
  uses: actions/checkout@v2
