Dependency management in Gradle

Gradle offers dependency resolution. It can be set up to use Maven's Central Repository. Let's consider a sample Gradle build (in a file called build.gradle):

apply plugin: 'java'

repositories {
    mavenCentral()
}

We instructed Gradle that we want to build a Java project and that the dependencies should be fetched from Maven's Central Repository. Now, we can simply declare the dependencies we require as follows:

dependencies {
  runtime group: 'org.hibernate', name: 'hibernate-core', version: '4.1.9.Final'
  testCompile group: 'junit', name: 'junit', version: '4.+'
}

The following Gradle build file declares two dependencies:

repositories {
    maven {
        url "http://repo.mycompany.com"
    }
}

Maven and Gradle both offer excellent support for building our sample RESTful service, and the full build scripts can be downloaded along with all the source code of this book. Now, let's turn our attention to the structure of our property management system.
