In the time of maven

Answer 1

Check out Gradle's documentation on multi-project builds.

Here's an example, with some extra dependencies. Just call gradle install in the root folder, and all will be built and put to your local repo.

Folder structure:

root
+--> build.gradle
+--> settings.gradle
+--> sdk
|    +--> build.gradle
+--> example
     +--> build.gradle

root/build.gradle:

allprojects {
  apply plugin: 'java'
  apply plugin: 'maven'

  group = 'myGroup'
  version = '0.1-SNAPSHOT'
}

root/settings.gradle:

include 'sdk'
include 'example'

root/sdk/build.gradle:

dependencies {
  // just an example external dep.
  compile group:'commons-lang', name:'commons-lang', version:'2.3'
}

root/example/build.gradle:

dependencies {
  compile project(':sdk')
  compile group:'log4j', name:'log4j', version:'1.2.16'
}

Answer 2

You need to publish your own library to your local repository. You can do that in the following way:

1. Add maven-publish plugin:

   plugins {
       // your other plugins come here...
       id 'maven-publish'
   }
   

2. Add the publishing section to your build file:

   publishing {
       publications {
           myCoolLibrary(MavenPublication) {
               from components.java
           }
       }
   }
   

3. Run gradle build publishToMavenLocal

   Find more details in the documentation.
