执行action/download-artifact@v2时无法找到关联工作流工件的问题求助

可能原因及解决步骤 #

1. Maven未生成WAR包 #

• 排查：查看Build with Maven步骤的日志，确认是否有Building war: .../target/xxx.war的输出。如果没有，说明打包配置存在问题：
  • 检查项目pom.xml，确保<packaging>标签设置为war（默认是jar类型）。
  • 将maven命令从mvn clean install改为mvn clean package，优先确保打包流程完成，避免install阶段的额外操作干扰。

2. 上传工件的路径配置错误 #

• 排查：查看Upload artifact for deployment job步骤的日志，如果显示No files were found with the provided path，说明路径配置有误：
  • 去掉路径中的${{ github.workspace }}和引号，直接使用相对路径target/*.war（GitHub Actions的工作目录默认就是仓库根目录，相对路径更可靠）。
  • 如果是多模块Maven项目，路径需调整为子模块名称/target/*.war。

3. 验证工件是否真的被上传 #

• 在上传工件前添加一个步骤，列出target目录内容，确认WAR包存在：

  - name: Check target files
    run: dir target
  

  查看该步骤日志，确认*.war文件存在后再执行上传操作。
