Get Started with Gadle• Download the latest Gradle release from Gradle website.• For running Gradle, add GRADLE_HOME/bin toyour PATH environment variable

& check your installation by typing gradle -v in command prompt.

• We run Gradle built using gradle command.It will look for the bulid.gradle as built script.

• Ex .1: Simple Hello world• build.gradle

task hello { // Task name hellodoLast { println 'Hello world!' } // Groovy script

}• Execution of a build script > gradle -q hello

> Hello world!

• Ex.2 :Task dependencies• task compile << {• println 'compiling source'• }

• task compileTest(dependsOn: compile) << {• println 'compiling unit tests'• }

• task test(dependsOn: [compile, compileTest]) << {• println 'running unit tests'• }

• task dist(dependsOn: [compile, test]) << {• println 'building the distribution'• }

• Few Commands : • Exclude a task : gradle dist -x test• Task by abbreviation• Abbreviated camel case task name :

Ex:compileTest as gradle compTest or even gradle cT• Selecting the build to be executed :

Ex:gradle -q -b subdir/myproject.gradle hello• Listing projects : gradle -q projects• Continue entire task execution when built failure --continue• Listing tasks : gradle -q tasks• List Dependencies : gradle dependencies• Report generation: --profile

• Defining a multi-project build• To define a multi-project build, we need to create a settings file in the root

directory of the source tree.• It specifies which projects to include in the build.• It must be called settings.gradle

• Example 7.11. Multi-project build - settings.gradle file settings.gradle• include "shared", "api", "services:webservice", "services:shared“• Refer the example for better clarity.
