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:

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
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.
