maven-publish-gradle-plugin

Based vanniktech/gradle-maven-publish-plugin 0.18.0 (14c1891) version. Add disableAndroidJavaDocsAddReferencesLinks configuration option to MavenPublishPluginExtension

Gradle plugin that creates a publish task to automatically upload all of your Java, Kotlin or Android libraries to any Maven instance. This plugin is based on Chris Banes initial implementation and has been enhanced to add Kotlin support and keep up with the latest changes.

Set up

`build.gradle`

groovy:

buildscript {
  repositories {
    mavenCentral()
  }
  dependencies {
    classpath 'io.github.panpf.maven-publish:maven-publish-gradle-plugin:${LAST_VERSION}'
  }
}

apply plugin: "com.github.panpf.maven.publish"

kotlin:

buildscript {
  repositories {
    mavenCentral()
  }
  dependencies {
    classpath("io.github.panpf.maven-publish:maven-publish-gradle-plugin:${LAST_VERSION}")
  }
}

plugins {
    id("com.github.panpf.maven.publish")
}

${LAST_VERSION}： (no include 'v')

Setting properties

To configure the coordinates of your published artifacts as well as the POM this plugin uses Gradle properties. It's generally recommended to set them in your gradle.properties file.

GROUP=com.test.mylibrary
POM_ARTIFACT_ID=mylibrary-runtime
VERSION_NAME=3.0.5

POM_NAME=My Library
POM_DESCRIPTION=A description of what my library does.
POM_INCEPTION_YEAR=2020
POM_URL=https://github.com/username/mylibrary/

POM_LICENSE_NAME=The Apache Software License, Version 2.0
POM_LICENSE_URL=https://www.apache.org/licenses/LICENSE-2.0.txt
POM_LICENSE_DIST=repo

POM_SCM_URL=https://github.com/username/mylibrary/
POM_SCM_CONNECTION=scm:git:git://github.com/username/mylibrary.git
POM_SCM_DEV_CONNECTION=scm:git:ssh://git@github.com/username/mylibrary.git

POM_DEVELOPER_ID=username
POM_DEVELOPER_NAME=User Name
POM_DEVELOPER_URL=https://github.com/username/

This Gradle plugin is using itself to publish any of the updates and sets the Gradle properties in this gradle.properties.

In multi module projects you can set most properties in the root gradle.properties file and then only set the module specific ones in the submodules. For example if you have two modules called runtime and driver you could only set POM_ARTIFACT_ID and POM_NAME in <project-dir>/runtime/gradle.properties and <project-dir>/driver/gradle.properties while sharing the rest by putting them into <project-dir>/gradle.properties.

Where to upload to

Without any further configuration the plugin has two tasks. publish which will upload to Maven Central (through Sonatype OSSRH) by default. To publish to the local maven repository on your machine (~/m2/repository) there is publishToMavenLocal.

In case you are using s01.oss.sonatype.org you need to configure that like this:

groovy:

allprojects {
    plugins.withId("com.github.panpf.maven.publish") {
        mavenPublish {
            sonatypeHost = "S01"
        }
    }
}

kotlin:

allprojects {
    plugins.withId("com.github.panpf.maven.publish") {
        configure<com.github.panpf.maven.publish.MavenPublishPluginExtension> {
            sonatypeHost = com.github.panpf.maven.publish.SonatypeHost.S01
        }
    }
}

The username and password for Sonatype OSS can be provided as Gradle properties called mavenCentralUsername and mavenCentralPassword to avoid having to commit them. You can also supply them as environment variables called ORG_GRADLE_PROJECT_mavenCentralUsername and ORG_GRADLE_PROJECT_mavenCentralPassword.

To remove the default repository set sonatypeHost to null.

You can add additional repositories to publish to using the standard Gradle APIs:

groovy:

publishing {
    repositories {
        maven {
            def releasesRepoUrl = "$buildDir/repos/releases"
            def snapshotsRepoUrl = "$buildDir/repos/snapshots"
            url = version.endsWith('SNAPSHOT') ? snapshotsRepoUrl : releasesRepoUrl
        }
    }
}

kotlin:

configure<PublishingExtension> {
    repositories {
        maven {
            val releasesRepoUrl = "$buildDir/repos/releases"
            val snapshotsRepoUrl = "$buildDir/repos/snapshots"
            url = if (version.endsWith("SNAPSHOT")) snapshotsRepoUrl else releasesRepoUrl
        }
    }
}

More information can be found in Gradle's documentation

You can also configure do not upload to mavenCentral:

groovy:

mavenPublish {
    sonatypeHost = null
}

kotlin:

configure<com.github.panpf.maven.publish.MavenPublishPluginExtension> {
    sonatypeHost = null
}

Note: To prevent looping behavior, especially in Kotlin projects / modules, you need to run the publish task with --no-daemonand --no-parallel flags

Signing

The plugin supports signing all of your release artifacts with GPG. This is a requirement when publishing to Maven Central - our default behavior. Any version ending in -SNAPSHOT will never be signed. Signing parameters can be configured via:

signing.keyId=12345678
signing.password=some_password
signing.secretKeyRingFile=/Users/yourusername/.gnupg/secring.gpg

It's best to place them inside your home directory, $HOME/.gradle/gradle.properties. You can find more information about these properties in Gradle's documentaion.

In case you want to use in memory signing keys, which works great for CI, you can specify them like this instead:

signingInMemoryKey=exported_ascii_armored_key
# Optional.
signingInMemoryKeyId=24875D73
# If key was created with a password.
signingInMemoryKeyPassword=secret

These properties can also be provided as environment variables by prefixing them with ORG_GRADLE_PROJECT_

It is possible to disable signing of release artifacts directly in your build scripts (takes precedence):

groovy:

mavenPublish {
  releaseSigningEnabled = false
}

kotlin:

configure<com.github.panpf.maven.publish.MavenPublishPluginExtension> {
    releaseSigningEnabled = false
}

Alternatively, you can use a Gradle property which is recommended if you only want to sign certain builds or only build on certain machines.

RELEASE_SIGNING_ENABLED=false

Android Variants

By default, the "release" variant will be used for publishing. Optionally, a specific variant can be defined by the plugin extension:

groovy:

mavenPublish {
  androidVariantToPublish = "demoDebug"  // or use project.property('PUBLISH_VARIANT'), etc.
}

kotlin:

configure<com.github.panpf.maven.publish.MavenPublishPluginExtension> {
    androidVariantToPublish = "demoDebug"
}

Releasing

Once publish is called, and if you're using a Nexus repository, you'll have to make a release. This can be done manually by following the release steps at sonatype.

Additionally, the plugin will create a closeAndReleaseRepository task that you can call after publish:

# prepare your release by assigning a version (remove the -SNAPSHOT suffix)
./gradlew publish --no-daemon --no-parallel
./gradlew closeAndReleaseRepository

It assumes there's only one staging repository active when closeAndReleaseRepository is called. If you have stale staging repositories, you'll have to delete them by logging at https://oss.sonatype.org (or you Nexus instance).

Known Issues

1.Cannot access https:developer.android.comreference or https://docs.oracle.com/javase/8/docs/api/ when executing the androidJavadocs() task

This problem usually occurs in China, just don’t add the above link in the following configuration:

groovy:

mavenPublish {
    disableAndroidJavaDocsAddReferencesLinks = true
}

kotlin:

configure<com.github.panpf.maven.publish.MavenPublishPluginExtension> {
    disableAndroidJavaDocsAddReferencesLinks = true
}

Base plugin

Starting with version 0.15.0 there is a base plugin. This new plugin has the same capabilities as the main plugin but does not configure anything automatically. In the current stage the APIs are still marked with @Incubating so they might change.

In your root build.gradle file you can do the general configuration for all modules in your project.

import SonatypeHost

allprojects {
    plugins.withId("com.github.panpf.maven.publish.base") {
        GROUP = "com.example.project"
        VERSION = "1.0.3-SNAPSHOT"

        mavenPublishing {
            publishToMavenCentral("DEFAULT")

            // Will only apply to non snapshot builds.
            // Uses credentials as described above, supports both regular and in memory signing.
            signAllPublications()

            pom {
                name = "My Library"
                description = "A description of what my library does."
                inceptionYear = "2020"
                url = "https ://github.com/username/mylibrary/"
                licenses {
                    license {
                        name = "The Apache License, Version 2.0"
                        url = "http://www.apache.org/licenses/LICENSE-2.0.txt"
                        distribution = "http://www.apache.org/licenses/LICENSE-2.0.txt"
                    }
                }
                developers {
                    developer {
                        id = "username"
                        name = "User Name"
                        url = "https://github.com/username/"
                    }
                }
                scm {
                    url = "https://github.com/username/mylibrary/"
                    connection = "scm:git:git://github.com/username/mylibrary.git"
                    developerConnection = "scm:git:ssh://git@github.com/username/mylibrary.git"
                }
            }

            // Alternatively to the DSL based POM configuration above you can define them
            // in Gradle properties
            pomFromGradleProperties()
        }
    }
}

kotlin:

import SonatypeHost

allprojects {
    plugins.withId("com.github.panpf.maven.publish.base") {
        GROUP = "com.example.project"
        VERSION = "1.0.3-SNAPSHOT"

        configure<com.github.panpf.maven.publish.MavenPublishBaseExtension> {
            publishToMavenCentral("DEFAULT")

            // Will only apply to non snapshot builds.
            // Uses credentials as described above, supports both regular and in memory signing.
            signAllPublications()

            pom {
                name = "My Library"
                description = "A description of what my library does."
                inceptionYear = "2020"
                url = "https ://github.com/username/mylibrary/"
                licenses {
                    license {
                        name = "The Apache License, Version 2.0"
                        url = "http://www.apache.org/licenses/LICENSE-2.0.txt"
                        distribution = "http://www.apache.org/licenses/LICENSE-2.0.txt"
                    }
                }
                developers {
                    developer {
                        id = "username"
                        name = "User Name"
                        url = "https://github.com/username/"
                    }
                }
                scm {
                    url = "https://github.com/username/mylibrary/"
                    connection = "scm:git:git://github.com/username/mylibrary.git"
                    developerConnection = "scm:git:ssh://git@github.com/username/mylibrary.git"
                }
            }
        }
    }
}

The above also works to configure the POM of the regular plugin without properties. It's also possible to use it in a project where some modules use the regular and some use the base plugin.

In the individual projects you can then configure publishing like this:

import JavaLibrary
import JavadocJar

apply plugin: "com.github.panpf.maven.publish.base"

mavenPublishing {
    // available options:
    //   - JavaLibrary
    //   - GradlePlugin
    //   - AndroidLibrary
    //   - KotlinJvm
    //   - KotlinJs
    //   - KotlinMultiplatform
    // the first parameter configures the javadoc jar, available options:
    //   - None
    //   - Empty
    //   - Javadoc
    //   - Dokka("dokkaHtml") - the parameter is the name of the Dokka task
    // second one is for whether to publish sources, optional, defaults to true (not supported for KotlinMultiplatform(
    // AndroidLibrary has a third parameter for which variant to publish, defaults to "release"
    configure(new JavaLibrary(new JavadocJar.Javadoc(), true))
}

kotlin:

import JavaLibrary
import JavadocJar

plugins {
    id("com.github.panpf.maven.publish.base")
}

configure<com.github.panpf.maven.publish.MavenPublishBaseExtension> {
    // available options:
    //   - JavaLibrary
    //   - GradlePlugin
    //   - AndroidLibrary
    //   - KotlinJvm
    //   - KotlinJs
    //   - KotlinMultiplatform
    // the first parameter configures the javadoc jar, available options:
    //   - None
    //   - Empty
    //   - Javadoc
    //   - Dokka("dokkaHtml") - the parameter is the name of the Dokka task
    // second one is for whether to publish sources, optional, defaults to true (not supported for KotlinMultiplatform(
    // AndroidLibrary has a third parameter for which variant to publish, defaults to "release"
    configure(JavaLibrary(JavadocJar.Javadoc(), true))
}
