Caching on Bitrise Android

When using caching on Bitrise, you would use cache-pull&csche-push steps. In this talk I talked about how to use them and how we can customize to enable/disable caching using git command and envman tool.

 gradle & maven
9. •cache-pull •Pull cache from remote server if available •cache-push •Check if cache needs to be updated •Upload the caching content if required Caching Steps
10. cache-pull _prepare: title: Prepare fastlane steps: - script: inputs: - content: |- bundle install --path vendor/bundle - cache-pull: {}

14. Workflow test: title: Run unit test before_run: - _prepare after_run: - _cache steps: - script: inputs: - content: |- bundle exec fastlane test
15. Workflow test: title: Run unit test before_run: - _prepare after_run: - _cache steps: - script: inputs: - content: |- bundle exec fastlane test
17. Try pushing library update
18. Again, 
 cached gradle / maven data is used
20. Want to re-build if certain files are modified

31. Bitrise re-built without cache successfully!
33. Summary
34. •Use cache-pull & cache-push steps for enabling caching on Bitrise •Configuration may be required •Ask Bitrise team for help :) Summary
35. Caching on Bitrise @shaunkawano Thank you!
