I'm configuring CircleCI to try and cache dependencies so I don't have to run yarn install on every single commit.
This is what my config.yml file looks like:
version: 2.1
jobs:
build-and-test-frontend:
docker:
- image: circleci/node:14
steps:
- checkout
- restore_cache:
name: Restore Yarn Package Cache
keys:
- yarn-packages-{{ checksum "yarn.lock" }}
- run:
working_directory: ./frontend/tests
name: Run jest tests
command: |
yarn install --frozen-lockfile --cache-folder ~/.
yarn test
- save_cache:
name: Save Yarn Package Cache
key: yarn-packages-{{ checksum "yarn.lock" }}
paths:
- ~/.cache/yarn
workflows:
sample:
jobs:
- build-and-test-frontend
But when either restore_cache or save_cache attempts to run, I get the following error:
error computing cache key: template: cacheKey:1:17: executing "cacheKey" at <checksum "yarn.lock">: error calling checksum: open /home/circleci/project/yarn.lock: no such file or directory
I'm brand new to using CircleCI so I'm not sure how to interpret this. What can I do to fix this?
EDIT:
This is the structure of my directory:
--project_root
|
|--frontend
|-node_modules/
|-public/
|-src/
|-tests/
|-package.json
|-yarn.lock
It's hard for me to give a great answer since I can't see your files in the repo but the config you have now suggest that the yarn.lock file you have is not in the root of the repo but rather in ./frontend/tests.
If that's where it is and that's where you want to keep it, then I'd suggest moving the working_dir key from the step level to the job level. This will then apply it to every step including the caching steps. Then they should find the file they are looking for.
Update:
Thanks for the repo tree. According to that you likely want to have your config like this:
version: 2.1
workflows:
sample:
jobs:
- build-and-test-frontend
jobs:
build-and-test-frontend:
docker:
- image: cimg/node:14.17
working_directory: ./frontend
steps:
- checkout
- restore_cache:
name: Restore Yarn Package Cache
keys:
- yarn-packages-{{ checksum "yarn.lock" }}
- run:
name: Run jest tests
command: |
yarn install --frozen-lockfile --cache-folder ~/.
yarn test
- save_cache:
name: Save Yarn Package Cache
key: yarn-packages-{{ checksum "yarn.lock" }}
paths:
- ~/.cache/yarn
You'll notice a few things here:
I moved workflows to that top. That's just a personal stylistic choice but I believe it helps keep your config readable as it grows.
I moved working_directory to the job level instead of the step it was on.
I set working_directory to the frontend directory. Most filepaths on CircleCI will be relative to the working_directory. Since that's where yarn.lock is, that's where I set it.
I change the image from circleci/node:14 to cimg/node:14. The images in the circleci namespaces are deprecated. Going forward, you'll want to use the newer CircleCI images which are in the cimg namespace.

I have configured my cypress test suite to circleci pipeline. The issue I am facing is that when I pushed my git branch or accept a pull request for the branch connected to the circle ci pipeline, it starts to run the test. I just don't need that I'm preferred to run the pipeline manually from the circle ci dashboard. Can someone guide me to fix the issue please? Attached my circleci yaml file below..
version: 2
jobs:
- request-testing:
type: approval
build:
docker:
- image: cypress/base:14.16.0
environment:
## this enables colors in the output
TERM: xterm
working_directory: ~/app
parallelism: 4
resource_class: large
steps:
- checkout
- restore_cache:
keys:
- v1-deps-{{ .Branch }}-{{ checksum "package.json" }}
- v1-deps-{{ .Branch }}
- v1-deps
- run:
name: Install Dependencies
command: npm ci
- save_cache:
key: v1-deps-{{ .Branch }}-{{ checksum "package.json" }}
# cache NPM modules and the folder with the Cypress binary
paths:
- ~/.npm
- ~/.cache
#run: $(npm bin)/cypress run
- run: $(npm bin)/cypress run --parallel --record --key 4
The simple way would be to edit the CircleCI webhook in your VCS repository settings, and unselect both the "Pushes" and "Pull requests" events.
This way there won't be any webhook delivery sent to CircleCI for these types of events, and therefore no build will be triggered.
I am getting the error Not uploading cache {name of branch} due to policy in my gitlab runner. My .yaml file looks like this:
stages:

# cache using branch name

I was wondering why it always fails to upload, and thereby fails to extract the cache. Any tips or corrections welcome. Here is a screenshot of where it fails:
You have the following set:
cache:
key: ${CI_COMMIT_REF_SLUG}
paths:
- .yarn
- node_modules/
policy: pull
Which sets a pipeline-global precedent that you only want to (policy: pull) pull from the cache.
You'll want to read https://docs.gitlab.com/ee/ci/yaml/#cachepolicy
If you omit the policy: piece, the default is to pull-push (which will get your cache uploading).
I tend to have my pipelines structured a little different than yours, though. I typically have a "prep" step that I define, and then run the yarn install once there:
"Installing Dependencies":
image: node:lts
stage: Prep
cache:
paths:
- .yarn
- node_modules/
policy: pull-push
script:
yarn install
...
Note: Then you can leave your global policy of 'pull', since this one job will have an override to pull-push.
Then, you can remove the yarn install on all other tasks, as the cache will be restored.
The error i get is
error computing cache key: template: cacheKey:1:30: executing "cacheKey" at <checksum "~/project/package-lock.json">: error calling checksum: open /home/circleci/project/package-lock.json: no such file or directory
and my config.yaml file is
version: 2.1
orbs:
node: circleci/node#3.0.0
workflows:
node-tests:
jobs:
- node/test
How do I tell CircleCI to use the yarn.lock file?
If defining your own jobs, ou can change the cache key in your job's steps to use yarn.lock. Example from the docs:
- restore_cache:
name: Restore Yarn Package Cache
keys:
- yarn-packages-{{ checksum "yarn.lock" }}
- run:
name: Install Dependencies
command: yarn install --immutable
- save_cache:
name: Save Yarn Package Cache
key: yarn-packages-{{ checksum "yarn.lock" }}
paths:
- ~/.cache/yarn
I'm using GitLab CI.
I have 2 jobs in the build stage that build differently my app. The 2 jobs upload a cache for the branch. I use the compiled sources to launch some tests in the test stage.
build:
stage: build
script:
- ./gradlew build --build-cache --quiet
cache:
key: ${CI_COMMIT_REF_SLUG}
paths:
- "*/build"
build_with_different_conf:
stage: build
script:
- ./gradlew buildDiff --build-cache --quiet
cache:
key: ${CI_COMMIT_REF_SLUG}
paths:
- "*/build"
Test:
stage: test
script:
- ./gradlew test --build-cache
In my example, the job build_with_different_conf take more time to finish.
My question is : Is the last finishing build job upload the cache and replace the cache from the first build job or is it merging files whith the precedent job ?
Thanks.
From what i understand you are using global cache for gradle dependencies.
Than you want to have some kind of job, to job cache.
I would do it this way, more or less.
stages:
- build
- test
cache:
paths:
- <your_gradle_cache>
build_classes:
stage: build
script:
- ./gradlew build --build-cache --quiet
artifacts:
expire_in: 1d
paths:
- <your_build_dir>
build_war:
stage: build
dependencies:
- build_classes
script:
- ./gradlew buildDiff --build-cache --quiet
artifacts:
expire_in: 1w
paths:
- <path_to_your_war>
test_classes:
stage: test
dependencies:
- build_war
script:
- ./gradlew test --build-cache
test_war:
stage: test
dependencies:
- build_war
script:
- test # some kind of test to assure your war is in good condition
In this configuration:
build_classes --[.classes]--> build_war -> [.war]
| |
[.classes] [.war]
| |
V V
test_classes test_war
PS. Dont forget you can use shell (or whatever your runner's os) to debug, understand more about this. You can put ls -la all over the place.
build:
stage: build
Same stage jobs runs in parallel.
cache:
key: ${CI_COMMIT_REF_SLUG}
paths:
- "*/build"
Cache files are managed by cache:key. It means if you're using same cache:key for different jobs they'll share same cache.zip file across jobs even you're defining different cache:paths. If you're using same key, but different path then your cache won't be effective, because of every job will overwrite cache.zip file with different path contents.
In your case you're using same cache:key across different jobs.
cache:
key: ${CI_COMMIT_REF_SLUG}
paths:
- "*/build"
It means last finished job will overwrite the cache.zip file not merge and will be used for next job and subsequent pipeline jobs with same key defined.
Bonus:
Test:
stage: test
script:
- ./gradlew test --build-cache
Also beware that if this job requires */build directory contents to exist, you have to be careful and better to use artifacts instead. Cache doesn't always exist and it's provided as best effort delivery.
For example I use gitlab ci's cache like this.
nodejs_test:
stage: test
image: node:12.13-alpine
before_script:
- npm install
script:
- yarn test
cache:
key:
files:
# New cache key will be computed on each package.json change.
- package.json
paths:
- node_modules/
nodejs_build:
stage: build
image: node:12.13-alpine
before_script:
# In case if we miss cache, we can simply install packages again.
# If cache is there npm install won't download them again.
- npm install
script:
- yarn build
cache:
policy: pull # totally optional
key:
files:
- package.json
prefix: ${CI_COMMIT_REF_SLUG}
paths:
- node_modules/
New to the world of CircleCI and cannot seem to get anything apart from the first job to run.
I've tried all sorts of things from removing line breaks to renaming the job to "test", swapping the order of the first job and the second job, but nothing works.
Is there something I need to change in the project config such as defining jobs ahead of time?

You're missing the Workflows section of the config. The part that tells CircleCI which jobs are available and how to run them.
https://circleci.com/docs/2.0/workflows/
Also, the precompile_assets job will fail because it doesn't have any files from your repo. You'd need to have a checkout, or utilize workspaces (also available in my link above) in order to provide it files.
