---------------------------------
Summary: Integrate Maven Build cache to speed up building
Key: UNOMI-892
URL: https://issues.apache.org/jira/browse/UNOMI-892
Project: Apache Unomi
Issue Type: Sub-task
Components: unomi(-core)
Affects Versions: unomi-3.0.0
Reporter: Serge Huber
Fix For: unomi-3.0.0
Implement Maven Build Cache to optimize build times and improve CI/CD pipeline
performance. The project currently has specific configurations for Karaf
packaging and integration tests that need to be considered in the cache
implementation.
Current Setup:
1. Karaf Package Configuration:
- Using Karaf version 4.2.15
- Custom OSGi bundle configurations
- Specific library versions for Karaf packaging (xerces, servicemix.specs,
etc.)
- Integration with Elasticsearch/OpenSearch
2. Integration Tests Configuration:
- Currently has maven.build.cache.skip=true in itests/pom.xml
- Uses PaxExam for container testing
- Complex dependency management with Karaf BOM
- Integration with Elasticsearch/OpenSearch for testing
Implementation Tasks:
1. Enable Maven Build Cache:
- Add maven.build.cache.enabled=true to root pom.xml
- Configure cache location and settings
- Set appropriate cache TTL and size limits
2. Optimize Cache Configuration:
- Review and adjust cache settings for Karaf package
- Configure cache exclusions for volatile resources
- Set up cache sharing between CI/CD pipelines
3. Integration Tests Considerations:
- Evaluate removing maven.build.cache.skip=true from itests
- Configure cache settings for test resources
- Ensure test reproducibility with caching
4. Documentation:
- Update build documentation with cache configuration
- Document cache troubleshooting steps
- Add cache maintenance procedures
Technical Details:
- Current Maven version: 3.x
- Java version: 11
- Build profiles: apache-release, integration-tests
Expected Benefits:
1. Faster build times in CI/CD pipelines
2. Reduced network bandwidth usage
3. Improved developer build experience
4. Better resource utilization
Acceptance Criteria:
1. Maven Build Cache successfully implemented
2. Build times improved by at least 30%
3. All tests pass with cache enabled
4. Documentation updated
5. No regression in build reproducibility
Priority: Medium
Labels: build-optimization, maven, performance
