CircleCi 2.0 working with project inside the subdirectory

Question

I am trying to integrate my springboot tutorial project with CircleCi.

My project is inside a subdirectory inside a Github repository and I get the following error from CircleCi.

Goal requires a project to execute but there is no POM in this directory (/home/circleci/recipe). Please verify you invoked Maven from the correct directory.

I can't figure out how to tell circle-ci my project is inside a subdirectory. I have tried a couple of things, as well as trying to cd inside 'recipe' but it does not work or even feel right.

Here is the structure of my project:

Spring-tutorials
 |
 +-- projectA
 |    
 +-- recipe
 |   | +--pom.xml

Here is my config.yml

# Java Maven CircleCI 2.0 configuration file
#
# Check https://circleci.com/docs/2.0/language-java/ for more details
#
version: 2
jobs:
  build:
    docker:
      # specify the version you desire here
      - image: circleci/openjdk:8-jdk

      # Specify service dependencies here if necessary
      # CircleCI maintains a library of pre-built images
      # documented at https://circleci.com/docs/2.0/circleci-images/
      # - image: circleci/postgres:9.4

    working_directory: ~/recipe

    environment:
      # Customize the JVM maximum heap limit
      MAVEN_OPTS: -Xmx3200m

    steps:
      - checkout
      - run: cd recipe/; ls -la; pwd;

      # Download and cache dependencies
      - restore_cache:
          keys:
          - recipe-{{ checksum "pom.xml" }}
          # fallback to using the latest cache if no exact match is found
          - recipe-

      - run: cd recipe; mvn dependency:go-offline

      - save_cache:
          paths:
            - ~/recipe/.m2
          key: recipe-{{ checksum "pom.xml" }}

      # run tests!
      - run: mvn integration-test

Answer 1

I managed to fix the issue. I believe the combination of

    working_directory: ~/spring-tutorial/recipe

and of

  - checkout:
      path: ~/spring-tutorial

made it work.

Here is my working config.yml:

# Java Maven CircleCI 2.0 configuration file
#
# Check https://circleci.com/docs/2.0/language-java/ for more details
#
version: 2
jobs:
  build:
    working_directory: ~/spring-tutorial/recipe
    docker:
      # specify the version you desire here
      - image: circleci/openjdk:8-jdk

      # Specify service dependencies here if necessary
      # CircleCI maintains a library of pre-built images
      # documented at https://circleci.com/docs/2.0/circleci-images/
      # - image: circleci/postgres:9.4

    environment:
      # Customize the JVM maximum heap limit
      MAVEN_OPTS: -Xmx3200m

    steps:
      - checkout:
          path: ~/spring-tutorial

      # Download and cache dependencies
      - restore_cache:
          keys:
          - recipe-{{ checksum "pom.xml" }}
          # fallback to using the latest cache if no exact match is found
          - recipe-

      - run: mvn dependency:go-offline

      - save_cache:
          paths:
            - ~/.m2
          key: recipe-{{ checksum "pom.xml" }}

      # run tests!
      - run: mvn integration-test
