[JAVA] Notes on migrating from CircleCI 1.0 to 2.0

Get an overview on this page http://tech.smarthr.jp/entry/2017/07/12/073000

Official documentation of the migration procedure https://circleci.com/docs/2.0/migrating-from-1-2/

Documentation that uses config-translation Endpoint https://circleci.com/docs/2.0/config-translation/

Use config-translation Endpoint to get the configuration file.

Suppose the build page on CircleCI is the following URL:


In the above case, the config-translation Endpoint would be a URL like this: Here, the branch is specified as develop.


The file is downloaded with the file name config-translation.

NG pattern I set the user name of my GitHub account to : username, and the following response result was obtained.

  "message" : "{\"message\":\"Not Found\",\"documentation_url\":\"https://developer.github.com/v3/repos/#get\"}"

Incorporate the downloaded configuration file into the project.

Refer to the following https://circleci.com/docs/2.0/migrating-from-1-2/

Create a .circleci folder in the project root, move the downloaded configuration file to it, and rename the file to config.yml.

$ mkdir .circleci
$ mv /hoge/config-translation .circleci/config.yml

Add the description about Deployment.

There is no description of Deployment in the downloaded configuration file, so you need to write it yourself.

An error occurs in maven integration-test.

#!/bin/bash --login
mvn integration-test

It is said that pom.xml does not exist. pom.xml exists in /server/pom.xml. In 1.0, the following description was OK.

  build_dir: server

In 2.0, it is converted as follows, but since it checks out to working_directory, it is changed to ~ / topgate / hogehoge / server / server instead of ~ / topgate / hogehoge / server. , pom.xml existed, and without pom.xml, an error occurred.

version: 2
    working_directory: ~/topgate/hogehoge/server

I can think of the following two solutions. Proposal (1) Set working_directory: ~ / topgate / hogehoge / server / server as an option when executing the mvn command.

    - run:
        working_directory: ~/topgate/hogehoge/server/server
        command: mvn dependency:go-offline || true

Proposal (2) Set path: ~ / topgate / hogehoge in the checkout command and specify the next higher level folder.

    - checkout:
        path: ~/topgate/hogehoge

I got stuck in config.yml

Workflows didn't work and I didn't notice the difference in the following description and got stuck.

NG pattern (filters is in the same position as build.)

      - build:
            only: /.*/

OK pattern (filters is the child position of build.)

      - build:
              only: /.*/

Job doesn't respond with git tag

In 1.0, in order to deploy with git tag, the following description was made.

    tag: /release-.*/
#・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ Omitted ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・
    branch: develop

In 2.0, the job does not start with git tag, but the job starts using workflows.

Git Tag Job Execution https://circleci.com/docs/2.0/workflows/#git-tag-job-execution

Jobs with 2.0 respond to branch changes by default, but not to tagging. So, you need to create a filter for tag using filters so that the job starts with tagging.

Actually, it was described as follows.

version: 2
    #・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ Omitted ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・
    - deploy:
        name: deploy to prod
        command: |
            if [[ "${CIRCLE_TAG}" =~ ^release-.* ]]; then
                #・ ・ ・ ・ ・ ・ ・ ・ ・ Deploy command (omitted) ・ ・ ・ ・ ・ ・ ・ ・
    - deploy:
        name: deploy to dev
        command: |
            if [ "${CIRCLE_BRANCH}" == "develop" ]; then
                #・ ・ ・ ・ ・ ・ ・ ・ ・ Deploy command (omitted) ・ ・ ・ ・ ・ ・ ・ ・
#・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ Omitted ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・
  version: 2
      - build:
              only: /.*/
