If we have a directory where we want to publish our publications, we must add it to the publishing configuration block. Inside the block, we add a repositories configuration block containing one or more named repositories. For the combination of each publication and repository, Gradle creates a task with the publish<publicationName>To<repositoryName>Repository name pattern.

We define a simple directory repository in the next example build file with the name localRepo:

apply plugin: 'ivy-publish'
apply plugin: 'java'

version = '2.1.DEVELOPMENT'
group = 'book.gradle'

repositories {
  jcenter()
}

dependencies {
  compile 'org.springframework:spring-context:4.1.4.RELEASE'
}

publishing {

  publications {
    publishJar(IvyPublication) {
      module = 'sample'

     ...
