# The Distribution Plugin

version 5.4.1

The Distribution Plugin facilitates building archives that serve as distributions of the project. Distribution archives typically contain the executable application and other supporting files, such as documentation.

## Usage

To use the Distribution Plugin, include the following in your build script:

Example 1. Using the Distribution Plugin
build.gradle

    plugins {
        id 'distribution'
    }

build.gradle.kts

    plugins {
        distribution
    }

The plugin adds an extension named `distributions` of type DistributionContainer to the project. It also creates a single distribution in the distributions container extension named `main`. If your build only produces one distribution you only need to configure this distribution (or use the defaults).

You can run `gradle distZip` to package the main distribution as a ZIP, or `gradle distTar` to create a TAR file. To build both types of archives just run `gradle assembleDist`. The files will be created at `$buildDir/distributions/${project.name}-${project.version}.«ext»`.

You can run `gradle installDist` to assemble the uncompressed distribution into `$buildDir/install/${project.name}`.

## Tasks

The Distribution Plugin adds a number of tasks to your project, as shown below.

`distZip` — Zip

  Creates a ZIP archive of the distribution contents.

`distTar` — Task

  Creates a TAR archive of the distribution contents.

`assembleDist` — Task

  Depends on: `distTar`, `distZip`

  Creates ZIP and TAR archives of the distribution contents.

`installDist` — Sync

  Assembles the distribution content and installs it on the current machine.

For each additional distribution you add to the project, the Distribution Plugin adds the following tasks, where distributionName comes from Distribution.getName():

`distributionNameDistZip` — Zip

  Creates a ZIP archive of the distribution contents.

`distributionNameDistTar` — Tar

  Creates a TAR archive of the distribution contents.

`assembleDistributionNameDist` — Task

  Depends on: `distributionNameDistTar`, `distributionNameDistZip`

  Creates ZIP and TAR archives of the distribution contents.

`installDistributionNameDist` — Sync

  Assembles the distribution content and installs it on the current machine.

The following sample creates a `custom` distribution that will cause four additional tasks to be added to the project: `customDistZip`, `customDistTar`, `assembleCustomDist`, and `installCustomDist`:

Example 2. Adding extra distributions
build.gradle

    distributions {
        custom {
            // configure custom distribution
        }
    }

build.gradle.kts

    distributions {
        create("custom") {
            // configure custom distribution
        }
    }

Given that the project name is `myproject` and version `1.2`, running `gradle customDistZip` will produce a ZIP file named `myproject-custom-1.2.zip`.

Running `gradle installCustomDist` will install the distribution contents into `$buildDir/install/custom`.

## Distribution contents

All of the files in the `src/$distribution.name/dist` directory will automatically be included in the distribution. You can add additional files by configuring the Distribution object that is part of the container.

Example 3. Configuring the main distribution
build.gradle

    distributions {
        main {
            baseName = 'someName'
            contents {
                from 'src/readme'
            }
        }
    }

build.gradle.kts

    distributions {
        main {
            baseName = "someName"
            contents {
                from("src/readme")
            }
        }
    }

In the example above, the content of the `src/readme` directory will be included in the distribution (along with the files in the `src/main/dist` directory which are added by default).

The `baseName` property has also been changed. This will cause the distribution archives to be created with a different name.

## Publishing

A distribution can be published using the Ivy Publish Plugin or Maven Publish Plugin, or via the original publishing mechanism using the `uploadArchives` task.

### Using the Ivy/Maven Publish Plugins

To publish a distribution to an Ivy repository with the Ivy Publish Plugin, simply add one or both of its archive tasks to an IvyPublication. The following sample demonstrates how to add the ZIP archive of the `main` distribution and the TAR archive of the `custom` distribution to the `myDistribution` publication:

Example 4. Adding distribution archives to an Ivy publication
build.gradle

    plugins {
        id 'ivy-publish'
    }

    publishing {
        publications {
            myDistribution(IvyPublication) {
                artifact distZip
                artifact customDistTar
            }
        }
    }

build.gradle.kts

    plugins {
        `ivy-publish`
    }

    publishing {
        publications {
            create<IvyPublication>("myDistribution") {
                artifact(tasks.distZip.get())
                artifact(tasks["customDistTar"])
            }
        }
    }

Similarly, to publish a distribution to a Maven repository using the Maven Publish Plugin, add one or both of its archive tasks to a MavenPublication as follows:

Example 5. Adding distribution archives to a Maven publication
build.gradle

    plugins {
        id 'maven-publish'
    }

    publishing {
        publications {
            myDistribution(MavenPublication) {
                artifact distZip
                artifact customDistTar
            }
        }
    }

build.gradle.kts

    plugins {
        `maven-publish`
    }

    publishing {
        publications {
            create<MavenPublication>("myDistribution") {
                artifact(tasks.distZip.get())
                artifact(tasks["customDistTar"])
            }
        }
    }

### Using the `uploadArchives` task

The Distribution Plugin adds the distribution archives as default publishing artifact candidates. With the Maven Plugin applied, the distribution ZIP file will be published when running `uploadArchives` if no other default artifact is configured.

Example 6. Publishing the distribution ZIP with the Maven Plugin
build.gradle

    plugins {
        id 'maven'
    }

    uploadArchives {
        repositories {
            mavenDeployer {
                repository(url: "file://some/repo")
            }
        }
    }

build.gradle.kts

    plugins {
        maven
    }

    tasks.named<Upload>("uploadArchives") {
        repositories.withGroovyBuilder {
            "mavenDeployer" {
                "repository"("url" to "file://some/repo")
            }
        }
    }
