GitHub Action部署阶段报错：Author identity unknown问题求助

这个错误和GITHUB_TOKEN无关，核心原因是GitHub Actions的runner环境未配置git提交所需的用户身份信息，同时你的配置里还有一个拼写错误：

1. 配置git用户身份 #

在执行git commit前，必须先设置git的用户名和邮箱。推荐使用GitHub官方的机器人身份，在Commit and Push Semantic Snapshot Version步骤的run命令开头添加以下配置：

git config --local user.name "github-actions[bot]"
git config --local user.email "github-actions[bot]@users.noreply.github.com"

2. 修正GITHUB_TOKEN的拼写错误 #

你在env中写的GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}t多了末尾的t，这会导致token无效，需要改为：

GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

修改后的完整deploy任务 #

deploy:
  needs: test  # Runs when 'test' job is completed
  runs-on: ubuntu-latest

  steps:
  - uses: actions/checkout@v3
  - name: Set up JDK 20
    uses: actions/setup-java@v3
    with:
      java-version: '20'
      distribution: 'adopt'
      cache: 'maven'
  - name: Read Current Snapshot Version
    id: read_snapshot_version
    run: echo ::set-output name=current_snapshot_version::$(grep -oPm1 "(?<=<version>)[^<]+" pom.xml | grep -E "SNAPSHOT")
  - name: Semantic Versioning for Snapshot
    id: update_snapshot_version
    run: |
      current_snapshot_version="${{ steps.read_snapshot_version.outputs.current_snapshot_version }}"
      IFS='.' read -r -a version_parts <<< "$current_snapshot_version"
      major="${version_parts[0]}"
      minor="${version_parts[1]}"
      patch="${version_parts[2]}"
      # When the last digit is 100
      if [[ "$patch" == "100" ]]; then
        minor=$((minor + 1))  # Increase minor version number
        patch="0"             # Reset last digit
      else
        patch=$((patch + 1))
      fi
      new_snapshot_version="${major}.${minor}.${patch}-SNAPSHOT"
      echo "::set-output name=new_snapshot_version::${new_snapshot_version}"
      sed -i "s/<version>.*-SNAPSHOT<\/version>/<version>${new_snapshot_version}<\/version>/" pom.xml
  - name: Commit and Push Semantic Snapshot Version
    run: |
      git config --local user.name "github-actions[bot]"
      git config --local user.email "github-actions[bot]@users.noreply.github.com"
      git commit -am "SNAPSHOT version to ${{ steps.update_snapshot_version.outputs.new_snapshot_version }}"
      git push origin HEAD:main
