3. Era of Microservice And Mono-Repo Multi Project
4. Multi vs Mono Repo? Protocol Repo Client Repo Server Repo Commit Commit Commit Repo Protocol Client Server Commit!
5. Single vs Multi Application? Juice Repo Coffee Repo Client Protocol Server Client Protocol Server Beverage Repo Juice Client Juice Protocol Juice Server Coffee Client Coffee Protocol Coffee Server
6. Beverage Shop !"" coffee # $"" api # !"" client # !"" protocol # $"" server !"" juice # $"" api # !"" client # !"" protocol # $"" server $"" shop $"" server
7. Coffee Protocol and Client coffee/api/protocol/build.gradle.kts coffee/api/client/build.gradle.kts
8. Juice Protocol and Client juice/api/protocol/build.gradle.kts juice/api/client/build.gradle.kts
9. Gradle Configure Api

11. Project Configuration
12. Project Configuration
13. Gradle Recipe Plugin
14. Type Descriptor > Only one type descriptor per project > java-lib, java-boot-lib, java-boot-application, java-boot-servlet-application, java-boot-servlet-war > For hierarchical, vertical characteristics
15. Type Descriptors configureByType(type: String) configureByTypePrefix(typePrefix: String) configureByTypeSuffix(typeSuffix: String) configureByTypeHaving(varargs typelets: String) configureByTypeExpression(expr: String)
16. Label Descriptor > Multiple labels descriptors can be applied for one project > spring-boot1, spring-boot2, spring-boot-2dot2, junit4, junit5 > For horizontal characteristics
17. Label Descriptors configureByLabel(label: String) configureByLabels(varargs labels: String)
18. Composite Descriptors configure(byTypePrefix(“java”) and byTypeSuffix(“lib”)) configure(byTypePrefix(“java”) or byTypePrefix(“kotlin”)) configure(not(byTypePrefix(“scala”)))
19. Build Recipe Example
20. Coffee Protocol and Client coffee/api/protocol/build.gradle.kts apply(plugin=“java”) apply(plugin=“java-library”) dependencies { ... } coffee/api/client/build.gradle.kts
21. Beverage Shop !"" coffee # $"" api # !"" client - type=java-boot-lib # !"" protocol - type=java-lib # $"" server - type=java-boot-application !"" juice # $"" api # !"" client - type=java-boot-lib # !"" protocol - type=java-lib # $"" server - type=java-boot-application $"" shop $"" server - type=java-boot-application
22. Beverage Shop !"" yogurt $"" api !"" client - type=java-boot-lib !"" protocol - type=java-lib $"" server - type=java-boot-application
23. Goodness > Can organize similar sub projects > Less coupled with library dependency issues, by dependency label > Easy to add new modules or applications > Don’t repeat yourself
24. Recommend This Plugin to > Wanna reduce the cost to read gradle script > Wanna reduce the cost to maintain similar but different based applications > Can expect more similar applications > Start to manage multi-application mono-repo with gradle
