- All Known Implementing Classes:
MapBasedBuildCacheService
public interface BuildCacheService extends java.io.CloseableProtocol interface to be implemented by a client to a build cache backend.Build cache implementations should report a non-fatal failure as a
BuildCacheException. Non-fatal failures could include failing to retrieve a cache entry or unsuccessfully completing an upload a new cache entry. Gradle will not fail the build when catching aBuildCacheException, but it may disable caching for the build if too many failures occur.All other failures will be considered fatal and cause the Gradle build to fail. Fatal failures could include failing to read or write cache entries due to file permissions, authentication or corruption errors.
Every build cache implementation should define a
org.gradle.caching.configuration.BuildCacheconfiguration andBuildCacheServiceFactoryfactory.- Since:
- 3.5
