2. Gradle open source build automation system
builds upon the concepts of Apache Ant and Apache Maven
introduces a Groovy-based domain-specific language (DSL)

3. Why gradle?
Designed for multi-project builds which can grow to be quite large
Supports incremental builds
Tracks version upgrades

4. Polyglot builds
Linkedin uses Gradle to build 60 different programming languages

5. Tool integrations

6. Robust Dependency Management
Retrieve artifacts from any known binary repository, from public to private to local.
Flat

7. High Performance Builds
Gradle avoids unnecessary workload by caching:
remote metadata and artifacts
transitive dependency resolution
build execution plan
plugin inputs and outputs
test results

8. Packs all the gear to build enterprise software for the JVM
Test frameworks: JUnit, TestNG, Spock
Application frameworks: Java EE, Grails, Play!,
Code analysis cops: Checkstyle, CodeNarc, FindBugs,
JDepend, PMD, JaCoCo, Sonar

9. Reliable incremental builds

10. Partial builds
Gradle helps quickly accomplish the task by only building parts of the project

11. Efficient test execution
Filter tests by type, group or pattern
Run a single test
Rerun failed tests
Fail fast (stop on first failure)
Run tests in parallel
Distribute tests across multiple runtimes or machines
Skip tests when not needed

12. Gradle’s Daemon cuts startup time to near zero
enhances incremental builds
reuses the execution plan between subsequent builds
monitors changes to make builds reactive
lets you move seamlessly between the IDE and command line
performs preemptive work and maintenance tasks

13. From continuous integration to delivery
Get feedback sooner thanks to CI job caching and Gradle’s incremental build capabilities.
Activate Gradle’s numerous reports to inspect build results, troubleshoot problems and monitor build performance.
Use Gradle’s publishing tasks to turn the CI server into a publishing tool and release manager.
Push artifacts to a binary repository, documentation to a web server or your app to a staging or production environment.

14. Android studio
Automatic configuration of build variants and multiple APK file generation
ProGuard obfuscation
App-signing capabilities
Vector drawables
Project wizard for creating a Gradle-based project
Command line and IDE compatibility

15. Repositories repositories { jcenter() mavenCentral()
maven { url ' }
maven { url ' } }

16. Global parameters maven { credentials { username projectNexusUsername
password projectNexusPassword }
url '

26. Semantic Versioning v
MAJOR version when you make incompatible API changes,
MINOR version when you add functionality in a backwards-compatible manner, and
PATCH version when you make backwards-compatible bug fixes.

27. Alternatives Rake (DSL + Ruby) Apache Buildr (DSL + Ruby)
Scons (DSL + Python)
Simple Build Tool (DSL + Scala)

28. Off topic :) Dockercraft - simple Minecraft Docker client, to
visualize and manage Docker containers.
You can start, stop and remove containers interacting with levers and buttons.
Some Docker commands are also supported directly via Minecraft's chat window
