Grails - Building with Gradle

Description

The gradle is used for performing some tasks such as compilation, running tests etc on your application. You can get the version of the project, dependencies of the project, and repositories for finding dependencies in the build.gradle file.

 
buildscript {
    repositories {
        mavenLocal()
        maven { url "https://repo.grails.org/grails/core" }
    }
    dependencies {
        classpath "org.grails:grails-gradle-plugin:$grailsVersion"
        classpath "org.grails.plugins:hibernate5:${gormVersion-".RELEASE"}"
        classpath "com.bertramlabs.plugins:asset-pipeline-gradle:2.14.2"
    }
}

version "0.1"

Dependencies with Gradle

You can find the dependencies of the project in the dependencies section of the build.gradle file as shown below:

 
dependencies {
    compile "org.springframework.boot:spring-boot-starter-logging"
    compile "org.springframework.boot:spring-boot-autoconfigure"
    compile "org.grails:grails-core"
    compile "org.springframework.boot:spring-boot-starter-tomcat"
