A GitHub action to save / restore the coursier / sbt / mill / Ammonite caches of your build.
Add a coursier/cache-action@v6 step to your YAML workflow, like
steps:
- uses: actions/checkout@v4
- uses: coursier/cache-action@v6Always cached.
Add files to take into account in its cache key via extraFiles.
Cached when sbt files are found (any of *.sbt, project/**.scala, project/**.sbt, project/build.properties).
Add files to take into account in its cache key via extraSbtFiles.
Cached when mill files are found (any of .mill-version, ./mill).
Add files to take into account in its cache key via extraMillFiles.
Cached when Ammonite scripts are found (any of *.sc, */*.sc).
Add files to take into account in its cache key via ammoniteScripts.
Optional Root directory containing build definition sources (build.sbt, build.sc, etc.)
If the sbt or mill build definition files are in a sub-directory, pass the path to this sub-directory here.
Optional Override for the path of the coursier cache.
By default, the coursier cache is assumed to be in the default OS-dependent location.
Set this input to override that. Note that this action will also set the COURSIER_CACHE environment variable
if an override is specified, so that you don't have to set it yourself.
Optional Extra files to take into account in the cache key.
By default, sbt build definition files (*.sbt, project/**.{scala,sbt}, project/build.properties) and
mill build definition files (*.sc, ./mill) are hashed to uniquely identify the cached data. Upon
cache restoration, if an exact match is found, the cache is not saved again at the end of the job.
In case of no exact match, it is assumed new files may have been fetched; the previous cache for the
current OS, if any, is restored, but a new cache is persisted with a new key at the end of the job.
To take into account extra files in the cache key, pass via extraFiles either
- a single path as a string
- multiple paths in a JSON array, encoded in a string
Blobs are accepted (processed by @actions/glob).
Optional Extra sbt files to take into account in the sbt cache key. Same format as extraFiles.
Optional Extra mill files to take into account in the mill cache key. Same format as extraFiles.
Optional Extra Ammonite scripts to take into account in the Ammonite cache key. Same format as extraFiles.
Optional
Extra value to be appended to the coursier cache key.
See extraFiles for more details.
Optional
Extra content to take into account in the cache key.
See extraFiles for more details.
The content of extraHashedContent is taken into account in the hash for the coursier cache key.
Optional
Default: false
Set true if you don't want to use a job id as part of cache key.
Optional
Default: false
Set true if you don't want to use a matrix jobs as part of cache key.
cache-hit-coursier- A boolean value to indicate a match was found for the coursier cachecache-hit-sbt-ivy2-cache- A boolean value to indicate a match was found for the sbt-ivy2-cache cachecache-hit-mill- A boolean value to indicate a match was found for the mill cachecache-hit-ammonite- A boolean value to indicate a match was found for the ammonite cache
See Skipping steps based on cache-hit for info on using this output
Using the cache-hit-... outputs above, subsequent steps can be skipped when a cache hit occurs on a given key.
Example:
steps:
- uses: actions/checkout@v3
- uses: coursier/cache-action@v6
id: coursier-cache
- name: Fetch Dependencies
if: steps.coursier-cache.outputs.cache-hit-coursier != 'true'
