Andres Almiray on Gradle

Transcript

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).

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

17. SCENARIOS
18. ü  Executable/Launchable application ü  Executable fat jar ü  Installable application
19. EXECUTABLE LAUNCHABLE APPLICATION
20. <project ...> <build> <plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>exec-maven-plugin</artifactId> <version>1.2.1</version> <configuration> <mainClass>sample.Foo</mainClass> </configuration> </plugin> </plugins> </build> </project> $ mvn compile exec:java
21. apply plugin: 'java' apply plugin: 'application' mainClassName = 'sample.Foo' $ gradle run
22. EXECUTABLE FAT JAR
23. <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-shade-plugin</artifactId> <version>2.3</version> <configuration> <transformers> <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer"> <manifestEntries> <Main-Class>sample.Foo</Main-Class> </manifestEntries> </transformer> </transformers> </configuration> </plugin> <plugins> $ mvn package –DskipTests=true
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
28. BUT WAIT, THERE’S MORE
