CircleCI

Caching

steps:
  - restore_cache:
      keys:
        # when lock file changes, use increasingly general patterns to restore cache
        - gradle-repo-v1-{{ .Branch }}-{{ checksum "dependencies.lockfile" }}
        - gradle-repo-v1-{{ .Branch }}-
        - gradle-repo-v1-
  - save_cache:
      paths:
        - ~/.gradle/caches
        - ~/.gradle/wrapper
      key: gradle-repo-v1-{{ .Branch }}-{{ checksum "dependencies.lockfile" }}

Parallelisation

To run a set of concurrent jobs, you will need to add a workflows section to your existing .circleci/config.yml file.

The simple example below shows the default workflow orchestration with two concurrent jobs. The workflows key needs to have a unique name. In this example, the unique name is build_and_test. The jobs key is nested under the uniquely named workflow, and contains the list of job names. Since the jobs have no dependencies, they will run concurrently.
