Bitbucket pipelines for java artifacts and uploading to AWS s3

 I am new to bitbucket and for whatever reason trying to create a pipeline that builds a java artifact & publishing to an s3 bucket has proved a lot harder than it should.

There were various gotchas.

1. artifacts created in one step are not visible in the next
2. the aws-s3-deploy step insisted on uploading absolutely everything

Anyway, I took the weekend off & resolved my remaining issues in about 5 minutes. Isn't always the way. So here is the bitbucket-pipelines.yml file I have ended up with.

#  Template maven-build

#  This template allows you to test and build your Java project with Maven.
#  The workflow allows running tests, code checkstyle and security scans on the default branch.

# Prerequisites: pom.xml and appropriate project structure should exist in the repository.

pipelines:
  default:
    - parallel:
      - step:
          name: Build and Test
          caches:
            - maven
          script:
            - mvn -B verify --file pom.xml package
          artifacts:
            - $BITBUCKET_CLONE_DIR/target/v*
          after-script:
            - mkdir artifacts_for_deploy
            - mv target/v*war artifacts_for_deploy
            - pipe: atlassian/aws-s3-deploy:1.1.0
              variables:
                AWS_ACCESS_KEY_ID: $AWS_ACCESS_KEY_ID
                AWS_SECRET_ACCESS_KEY: $AWS_SECRET_ACCESS_KEY
                AWS_DEFAULT_REGION: 'us-west-1'
                S3_BUCKET:  $AWS_IFS_S3_ARTIFACT_BUCKET
                LOCAL_PATH: 'artifacts_for_deploy'
                COMMAND: 'upload'



      - step:
          name: checkstyle
          script:
            - pipe: atlassian/checkstyle-report:0.2.0
      - step:
          name: Security Scan
          script:
            # Run a security scan for sensitive data.
            # See more security tools at https://bitbucket.org/product/features/pipelines/integrations?&category=security
            - pipe: atlassian/git-secrets-scan:0.4.3
