Github Actions构建Tibco应用报错：当前目录无POM文件

问题场景 #

为Tibco应用搭建CI/CD流程，使用的Github Actions配置如下：

name: DEV workflow

on:
  push:
    branches: [ "dev" ]
  pull_request:
    branches: [ "dev" ]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - name: Checkout repository
      uses: actions/checkout@v2
 
    - name: Set up JDK 11
      uses: actions/setup-java@v3
      with:
        java-version: '11'
        distribution: 'temurin'
        cache: maven
    - name: Build with Maven
      run: mvn clean 

    # Optional: Uploads the full dependency graph to GitHub to improve the quality of Dependabot alerts this repository can receive
    - name: Update dependency graph
      uses: advanced-security/maven-dependency-submission-action@571e99aab1055c2e71a1e2309b9691de18d6b7d6

执行时Build with Maven步骤失败，错误信息：

无法直接查看Runner上的目标目录，需按以下步骤排查解决：

解决步骤 #

1. 先确认仓库中POM文件的位置 #

检查你的Github代码仓库，确认pom.xml是否在仓库根目录，还是存放在某个子目录下。Maven默认会在当前执行目录查找POM文件，若文件不在根目录则会触发该错误。

2. 添加目录检查步骤定位问题 #

在Checkout repository步骤之后，新增一个列出目录内容的步骤，通过Actions日志确认代码是否正确检出、POM文件的位置：

- name: List directory contents
  run: ls -la

3. 调整Maven执行路径 #

如果POM文件在子目录（例如./tibco-module），可以通过两种方式修正：

• 指定Maven的工作目录：

- name: Build with Maven
  run: mvn clean
  working-directory: ./tibco-module

• 直接在命令中指定POM文件路径：

- name: Build with Maven
  run: mvn clean -f ./tibco-module/pom.xml

4. 确认代码检出完整性 #

如果仓库包含子模块，需要在Checkout步骤中开启子模块拉取：

- name: Checkout repository
  uses: actions/checkout@v2
  with:
    submodules: true
