Gradle: Harder, Stronger, Better, Faster

Gradle is a build tool that uses conventions over configuration, allowing projects to customize builds while following standard conventions. It provides features like caching, configurable lifecycles, and a daemon to improve productivity. Gradle supports multi-project builds, plugins, and the Gradle wrapper. Common use cases include creating executable applications, executable jars, and installable applications using plugins.
Gradle: Harder, Stronger, Better, Faster
- 1. ANDRES ALMIRAY IX-CHEL RUIZ @AALMIRAY @IXCHELRUIZ HARDER, BETTER, STRONGER, FASTER
- 4. WHAT
- 5. Gradle is a build tool designed to take advantage of conventions over (not instead) configuration, while staying flexible enough to be customized to the needs of a particular project. In other words, the build tool bends to the project’s will, not the other way around.
- 6. Follows the Maven conventions. Expressive : Prefers a DSL for describing what needs to be done. Extensible : Has a growing an thriving plugin ecosystem. Productive : Fosters fast and reproducible builds. Convenient : It’s CI friendly (gradle wrapper).
- 7. WHY
- 11. Caching of task input and outputs Richer, configurable lifecycle The Gradle deamon The Gradle wrapper Multi-project builds are hassle free Plugin development is more intuitive Better documentation overall
- 12. HOW
- 13. $ curl -s get.gvmtool.net | bash $ gvm install gradle
- 14. . ├── build.gradle ├── pom.xml └── src ├── main │ └── java │ └── sample │ └── Foo.java └── test └── java └── sample └── FooTest.java
- 16. apply plugin: 'java' apply plugin: 'maven-publish' version = '0.0.0-SNAPSHOT' group = 'com.acme' repositories { jcenter() } dependencies { testCompile 'junit:junit:4.12' } 😎
- 17. SCENARIOS
- 18. ü Executable/Launchable application ü Executable fat jar ü Installable application
- 21. apply plugin: 'java' apply plugin: 'application' mainClassName = 'sample.Foo' $ gradle run 😎
- 24. plugins { id 'com.github.johnrengelman.shadow' version '1.2.1' } apply plugin: 'java' apply plugin: 'application' mainClassName = 'sample.Foo' repositories { jcenter() } dependencies { compile 'commons-lang:commons-lang:2.6' } $ gradle shadowJar 😎
- 25. Installable application . ├── bin │ ├── sample │ └── sample.bat └── lib ├── commons-lang-2.6.jar └── sample-0.0.0-SNAPSHOT.jar
- 26. 1. Add assembly plugin 2. Create assembly descriptor 1. Dist option for building the directory structure 2. Zip option for packing all in a single file 3. Create launch scripts (for all target platforms!) 4. Might require custom profiles OR configure the appassembler plugin 😐
- 27. apply plugin: 'java' apply plugin: 'application’ mainClassName = 'sample.Foo' repositories { jcenter() } dependencies { compile 'commons-lang:commons-lang:2.6' } $ gradle distZip 😎
- 29. $ gvm install lazybones $ lazybones create gradle-quickstart sample
