使用Jenkins CI/CD部署Spring Boot到Tomcat时遇Maven错误求解决

问题根源 #

Maven的生命周期阶段是大小写敏感的，你使用了大写开头的Clean，但Maven仅识别小写格式的clean阶段。

解决方案 #

• 修改Jenkins构建任务中的Maven命令，将大写的Clean替换为小写的clean。例如：
  错误命令：mvn Clean install
  正确命令：mvn clean install
• 检查Maven命令中的其他生命周期阶段（如install、deploy等），确保均为小写格式，避免同类问题。

错误验证 #

从你提供的错误信息可确认正确阶段名称：

[ERROR] Unknown lifecycle phase "Clean". You must specify a valid lifecycle phase or a goal in the format : or :[:]:. Available lifecycle phases are: validate, initialize, generate-sources, process-sources, generate-resources, process-resources, compile, process-classes, generate-test-sources, process-test-sources, generate-test-resources, process-test-resources, test-compile, process-test-classes, test, prepare-package, package, pre-integration-test, integration-test, post-integration-test, verify, install, deploy, pre-clean, clean, post-clean, pre-site, site, post-site, site-deploy. -> [Help 1]

列表中明确标注了小写的clean是合法的生命周期阶段。
