Gitlab CI gradle dependency cache

H

I'm building android on Gitlab CI and downloading dependencies each time is annoying. I tried caching:

$HOME/.gradle/
$HOME/.gradle/caches/
$GRADLE_HOME/caches/
$HOME/.m2/
.gradle/
build/
app/build/

The 26594th iteration of my .gitlab-ci.yml is here. I've installed gradle in my build environment because without caching gradlew downloads it every time, which takes even more time. The image I use for building is here. My CI server startup script can be found here. I assume that, if caching works, I won't see a list of my dependencies downloading on every build.

Build log:

I don't get the idea of this issue. You've already set up Gitlab CI for your Android testing and it works fine. Although, you want to during the test run Gradle and Android SDK installed on your Gitlab server, not download, just use existing, right? Could you add a log from failed build when you try to cache dependencies? – Boeotian 8/12, 2015 at 17:42

Added log from last build – Hafer 8/12, 2015 at 18:5

I configured my build to use these. Artifacts work fine. – Hafer 8/12, 2015 at 18:12

Is your question that: you do not want to download the dependencies each time but want to use them from the local cache? – Roi 8/12, 2015 at 21:30

Yes, I want to cache the dependencies, that might've not been clear. – Hafer 8/12, 2015 at 21:34

try the --offline flag – Roi 9/12, 2015 at 5:23

Where should I pass it? I don't see it among gitlab-multi-runner flags – Hafer 9/12, 2015 at 12:18

In the gradle command: gradle testDebug. BTW if you don't say @RaGe, I do not get a notification when you comment. – Roi 9/12, 2015 at 19:16

I'm confused that the question is met with so much confusion. To download the same 2GB over and over again for every commit is a bit insane, so how to cache it? I hacked in something like -v /srv/gitlab-runner/cache/:/cache/:rw and cp -ru stuff back and forth but I feel like missing something. Can't I tell my gitlab-ci-multi-runner to use a cache somehow? – Septavalent 16/1, 2016 at 4:26

@Septavalent - I understand your question and I am trying to do the same - ever solved it? Problem is the cache directive only has access to what is under the project directory and the Gradle cache is in $HOME – Tieback 17/3, 2016 at 2:32

@Tieback as I said, I copy the home folder back and forth. Didn't look into it again. – Septavalent 17/3, 2016 at 3:14

Turns out another post has the answer to this! There is a work around which is to run a before_script that sets the GRADLE_HOME to the directory of your project, which you can then slurp up with the cache directive.

before_script:
    - export GRADLE_USER_HOME=`pwd`/.gradle

cache:
  paths:
     - .gradle/wrapper
     - .gradle/caches

build:
  stage: build
  script:
     - ./gradlew assemble

test:
  stage: test
  script:
     - ./gradlew check

Tieback answered 17/3, 2016 at 2:40 Comment(7)

Great, this works. You just need - chmod +x ./gradlew in before_script. – Hafer 17/3, 2016 at 10:20

Wouldn't be a better solution to do something like export GRADLE_USER_HOME=/cache/.gradle? As it automatically cached always. – Feeney 22/9, 2016 at 11:2

@Feeney - possibly - if that works, maybe add that to the answer as an alternative / simpler way to do it. – Tieback 22/9, 2016 at 14:56

As far as I get it this does not work if you are using Shared Runners because each stage may run on a different one. – Din 9/1, 2017 at 12:4

@Din - I think you're right. You would need to use artifacts for that so the files are zipped up and made available to the other stages. – Tieback 9/1, 2017 at 16:31

This does not work with shared runners: gitlab.com/gitlab-org/gitlab-ci-multi-runner/issues/327 – Judaic 27/4, 2017 at 11:47

Maybe a remote gradle cache could help with shared runners? – Trolly 26/10, 2021 at 15:2

According to Kamil Trzciński

We run the caching outside the build container. So you can cache absolute paths, but since only /builds and /cache is transferred you have no-way to cache container-local files.

That means you need to put the gradle files into e.g. the /cache folder

before_script:
  - export GRADLE_USER_HOME=cache/.gradle

...

cache:
  key: "$CI_COMMIT_REF_NAME" #optional: per branch caching, can be omitted
  paths:
    - $GRADLE_USER_HOME/caches/
    - $GRADLE_USER_HOME/wrapper/
    - $GRADLE_USER_HOME/build-cache/

The /cache folder will be kept automatically, but I keep the cache config for clarity.

Judaic answered 27/4, 2017 at 11:46 Comment(3)

GRADLE_USER_HOME and the paths you specify seem not to match? – Bring 24/9, 2018 at 13:32

@Bring and PerLundberg I'm not sure what exactly you guys mean. If you have suggestions for improvement I welcome an edit or a clear explanation on what you think is incorrect, why and how to fix it – Judaic 5/11, 2018 at 13:41

I am curious, why did you need to add the cache definition in your .gitlab-ci.yaml since the /cache directory will be mounted regardless? Plus, the caching offered by GitLab works only for files in the build directory. – Controversial 6/1, 2019 at 4:31

We're running inside docker container on shared runner infrastructure using minio S3 backend to distribute the cache and landed on a solution somewhere along these lines:

variables:
  GRADLE_OPTS: "-Dorg.gradle.daemon=false -Dorg.gradle.vfs.watch=false -Dorg.gradle.caching=true"
  GRADLE_USER_HOME: .gradle/

default:
  image: yourfavoritegradlecontainer:latest
  cache: &gradle-cache
    key:
      files:
        - gradle/wrapper/gradle-wrapper.properties
    paths:
      - .gradle/caches/
      - .gradle/notifications/
      - .gradle/wrapper/
    policy: pull

build:
  stage: build
  cache:
    <<: *gradle-cache
    policy: pull-push
  script:
    - ./gradlew assemble
  artifacts:
    paths:
      - app/build/outputs/apk

test:
  stage: test
  script:
    - ./gradlew test

The cache gets invalidated, when the gradle-wrapper.properties file is changed and to prevent cache thrashing, only build job is allowed to upload the cache. Of course, you could always add key: "$CI_COMMIT_REF_NAME" to invalidate the cache more aggressively.

Seperately we export build artifacts, it supposedly helps, too.

GitLab is taking care of storing and restoring the cache, automatically from inside the container. This even works for a single shared runner.
