Error: Could not find or load main class org.apache.maven.wrapper.MavenWrapperMain when deploy maven project to app engine gg cloud with cicd

Question

我使用 cicd 将 maven 项目演示部署到 App Engine gg 云，这是错误构建日志 gg 应用程序：

Step #6 - "builder": ./mvnw: 219: ./mvnw: cannot open /workspace/.mvn/wrapper/maven-wrapper.properties: No such file Step #6 - "builder": /workspace/.mvn/wrapper/maven-wrapper.jar: No such file or directory Step #6 - "builder": Error: Could not find or load main class org.apache.maven.wrapper.MavenWrapperMain Step #6 - "builder": Caused by: java.lang.ClassNotFoundException: org.apache.maven.wrapper.MavenWrapperMain Step #6 - "builder": Done "./mvnw clean package --batch-mode -DskipTests" (589.295636ms)

这是pom.xml-

4.0.0 org.springframework.boot spring-boot-starter-parent 2.3.5.RELEASE com.example.simple_project 演示 0.0.1-快照 演示 Spring Boot

的演示项目

    </plugins>
</build>

这是.gitlab-ci.yml

image: larsdroid/integratieproject1:v1
services:
  - docker:dind

variables:
  DOCKER_DRIVER: overlay
  SPRING_PROFILES_ACTIVE: gitlab-ci

stages:
  - build
  - package
  - deploy

before_script:
   - echo "Start CI/CD"

maven-build:
  image: maven:3-jdk-11
  stage: build
  script:
    - "mvn package -B"
  artifacts:
    paths:
      - target/*.jar

deploy:
  stage: deploy
  script:
    - gcloud auth activate-service-account --key-file $GOOGLE_SERVICE_ACCOUNT_FILE
    - gcloud -q config set project ${GOOGLE_PROJECT_ID}
    - gcloud app deploy app.yaml --quiet --project $GOOGLE_PROJECT_ID
  only:
    - master

after_script:
  - echo "End CI/CD"

我在项目中已有一个目录.mvn/wrapper root project

Answer 1

/workspace/.mvn/wrapper/maven-wrapper.properties: No such file

该错误表明 Maven 正在尝试打开文件 maven-wrapper.properties，但未找到。请确认文件存在。
