java - Gitlab:您指定的目标需要一个项目来执行，但该目录中没有POM

Question

我尝试使用 gitlab CI 来构建和运行我的测试。

我使用默认的 .gitlab-ci.yml:

# This file is a template, and might need editing before it works on your project.
---
# Build JAVA applications using Apache Maven (http://maven.apache.org)
# For docker image tags see https://hub.docker.com/_/maven/
#
# For general lifecycle information see https://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html
#
# This template will build and test your projects as well as create the documentation.
#
# * Caches downloaded dependencies and plugins between invocation.
# * Verify but don't deploy merge requests.
# * Deploy built artifacts from master branch only.
# * Shows how to use multiple jobs in test stage for verifying functionality
#   with multiple JDKs.
# * Uses site:stage to collect the documentation for multi-module projects.
# * Publishes the documentation for `master` branch.

variables:
  # This will supress any download for dependencies and plugins or upload messages which would clutter the console log.
  # `showDateTime` will show the passed time in milliseconds. You need to specify `--batch-mode` to make this work.
  MAVEN_OPTS: "-Dhttps.protocols=TLSv1.2 -Dmaven.repo.local=.m2/repository -Dorg.slf4j.simpleLogger.log.org.apache.maven.cli.transfer.Slf4jMavenTransferListener=WARN -Dorg.slf4j.simpleLogger.showDateTime=true -Djava.awt.headless=true"
  # As of Maven 3.3.0 instead of this you may define these options in `.mvn/maven.config` so the same config is used
  # when running from the command line.
  # `installAtEnd` and `deployAtEnd` are only effective with recent version of the corresponding plugins.
  MAVEN_CLI_OPTS: "--batch-mode --errors --fail-at-end --show-version -DinstallAtEnd=true -DdeployAtEnd=true"

# Cache downloaded dependencies and plugins between builds.
# To keep cache across branches add 'key: "$CI_JOB_NAME"'
cache:
  paths:
    - .m2/repository

# This will only validate and compile stuff and run e.g. maven-enforcer-plugin.
# Because some enforcer rules might check dependency convergence and class duplications
# we use `test-compile` here instead of `validate`, so the correct classpath is picked up.
.validate: &validate
  stage: build
  script:
    - 'mvn $MAVEN_CLI_OPTS test-compile'

# For merge requests do not `deploy` but only run `verify`.
# See https://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html
.verify: &verify
  stage: test
  script:
    - 'mvn $MAVEN_CLI_OPTS verify site site:stage'
  except:
    - master

# Validate merge requests using JDK7
validate:jdk7:
  <<: *validate
  image: maven:3.3.9-jdk-7

# Validate merge requests using JDK8
validate:jdk8:
  <<: *validate
  image: maven:3.3.9-jdk-8

# Verify merge requests using JDK7
verify:jdk7:
  <<: *verify
  image: maven:3.3.9-jdk-7

# Verify merge requests using JDK8
verify:jdk8:
  <<: *verify
  image: maven:3.3.9-jdk-8


# For `master` branch run `mvn deploy` automatically.
# Here you need to decide whether you want to use JDK7 or 8.
# To get this working you need to define a volume while configuring your gitlab-ci-multi-runner.
# Mount your `settings.xml` as `/root/.m2/settings.xml` which holds your secrets.
# See https://maven.apache.org/settings.html
deploy:jdk8:
  # Use stage test here, so the pages job may later pickup the created site.
  stage: test
  script:
    - 'mvn $MAVEN_CLI_OPTS deploy site site:stage'
  only:
    - master
  # Archive up the built documentation site.
  artifacts:
    paths:
    - target/staging
  image: maven:3.3.9-jdk-8


pages:
  image: busybox:latest
  stage: deploy
  script:
    # Because Maven appends the artifactId automatically to the staging path if you did define a parent pom,
    # you might need to use `mv target/staging/YOUR_ARTIFACT_ID public` instead.
    - mv target/staging public
  dependencies:
    - deploy:jdk8
  artifacts:
    paths:
    - public
  only:
    - master

当我运行管道时，它失败并收到以下错误:

2288 [错误] 您指定的目标需要一个项目来执行，但此目录 (/builds/IceCristall/the-great-triggering) 中没有 POM。请验证您从正确的目录调用 Maven。 -> [帮助1]org.apache.maven.lifecycle.MissingProjectException:您指定的目标需要一个项目来执行，但此目录中没有 POM (/builds/IceCristall/the-great-triggering)。请验证您从正确的目录调用了 Maven。

当我正确理解此日志时，该项目是从路径下的 Docker 容器中的我的存储库复制的:/builds/IceCristall/the-great-triggering

现在执行mvn命令并没有找到pom.xml

我有点困惑，因为 pom.xml 位于“the-great-triggering”文件夹中。

此外，我找不到可以在 ci 配置文件中定义此路径的位置。

有人对问题所在以及我可以在哪里搜索它有建议吗？

Answer 1

错误消息显示:“此目录 (/builds/IceCristall/the-great-triggering) 中没有 POM。”。您确定已提交 pom.xml 文件并将其推送到存储库的所需分支吗？
