1. Submodules & dynamic submodules form the sub folder
2. Centralized scripts blocks
3. Centralized dependency names/versions
4. Generated sources
5. Integration tests
6. Wrapper
7. IDE plug-ins
8. Attributes in MANIFEST.MF
9. JaCoCo
   1. https://www.eclemma.org/jacoco/
   2. JaCoCo Plugin: https://docs.gradle.org/current/userguide/jacoco_plugin.html
10. "all" jar
    1. self-sufficient archive which contains both classes and dependencies needed to run an application
11. "sources" jar
    1. jar archive with source files, without unit/integration tests
12. The project local maven repository
13. Checkstyle
    1. http://checkstyle.sourceforge.net/
14. Maven publishing
15. Spring Boot
16. OSGi
17. gradle.properties in the build.gradle

How to

How to run checkstyle:

gradlew checkstyleMain

How to skip tests:

gradlew build -x test

How to run only integration tests:

gradlew build testIntegration -x test

How to force to refresh depnedencies

gradlew build --refresh-dependencies

How to generate wrapper with version 4.10

gradle wrapper --gradle-version 4.10

Gradle vs Maven

Maven

• ( ) declarative
• ( ) build Lifecycle
• (-) Transitive Dependencies -> "nearest definition"
• (+-) incremental build support: with takari-lifecycle (https://github.com/takari/takari-lifecycle)
• ( ) XML (easy to parse, better IDE integration, better back compatibility, complex to fail)
• (+) multi-module = child to parent
• (+) composite build: additional pom.xml (http://andresalmiray.com/composite-builds-with-maven-and-gradle/)
• (+) build profiles
• (+) wrapper: with takari-maven-plugin (https://github.com/takari/takari-maven-plugin)

Gradle

• ( ) imperative
• ( ) directed acyclic graph ("DAG") to determine the order in which tasks can be run
• (+) Transitive Dependencies -> latest, fail, custom
• (+) incremental build support.
• ( ) Groovy/etc. (short, flexible, more chances for shit, required more skill)
• (+) multi-module = parent to child
• (+) composite build: setting.gradle
• (+-) build profiles: using project property (-P)
• (+) wrapper
