A MavenPublication
is the representation/configuration of how Gradle should publish something in Maven format.
You directly add a named Maven Publication the project's publishing.publications
container by providing MavenPublication as the type.
publishing { publications { myPublicationName(MavenPublication) { // Configure the publication here } } }The default Maven POM identifying attributes are mapped as follows:
groupId
- project.group
artifactId
- project.name
version
- project.version
For certain common use cases, it's often sufficient to specify the component to publish, and nothing more (from(org.gradle.api.component.SoftwareComponent). The published component is used to determine which artifacts to publish, and which dependencies should be listed in the generated POM file.
To add additional artifacts to the set published, use the artifact(Object) and artifact(Object, org.gradle.api.Action) methods. You can also completely replace the set of published artifacts using setArtifacts(Iterable). Together, these methods give you full control over what artifacts will be published.
For any other tweaks to the publication, it is possible to modify the generated POM prior to publication. This is done using the MavenPom.withXml method of the POM returned via the getPom() method, or directly by an action (or closure) passed into pom(org.gradle.api.Action).
apply plugin: "java" apply plugin: "maven-publish" task sourceJar(type: Jar) { from sourceSets.main.allJava } publishing { publications { myPublication(MavenPublication) { from components.java artifact sourceJar { classifier "source" } pom.withXml { asNode().appendNode('description', 'A demonstration of Maven POM customization') } } } }

Creates a custom MavenArtifact to be included in the publication.
The artifact
method can take a variety of input:
apply plugin: "maven-publish" task sourceJar(type: Jar) { classifier "source" } publishing { publications { maven(MavenPublication) { artifact sourceJar // Publish the output of the sourceJar task artifact 'my-file-name.jar' // Publish a file created outside of the build artifact source: sourceJar, classifier: 'src', extension: 'zip' } } }
source
- The source of the artifact content.Creates an MavenArtifact to be included in the publication, which is configured by the associated action. The first parameter is used to create a custom artifact and add it to the publication, as per artifact(Object). The created MavenArtifact is then configured using the supplied action, which can override the extension or classifier of the artifact. This method also accepts the configure action as a closure argument, by type coercion.
apply plugin: "maven-publish" task sourceJar(type: Jar) { classifier "source" } publishing { publications { maven(MavenPublication) { artifact sourceJar { // These values will be used instead of the values from the task. The task values will not be updated. classifier "src" extension "zip" } artifact("my-docs-file.htm") { classifier "documentation" extension "html" } } } }
source
- The source of the artifact.config
- An action to configure the values of the constructed MavenArtifact.Provides the software component that should be published.
apply plugin: "java" apply plugin: "maven-publish" publishing { publications { maven(MavenPublication) { from components.java } } }
component
- The software component to publish.Returns the artifactId for this publication.
Returns the complete set of artifacts for this publication.
Returns the groupId for this publication.
The POM that will be published.
Returns the version for this publication.
Configures the POM that will be published. The supplied action will be executed against the getPom() result. This method also accepts a closure argument, by type coercion.
configure
- The configuration action.Sets the artifactId for this publication.
Clears any previously added artifacts from getArtifacts and creates artifacts from the specified sources. Each supplied source is interpreted as per artifact(Object). For example, to exclude the dependencies declared by a component and instead use a custom set of artifacts:
apply plugin: "java" apply plugin: "maven-publish" task sourceJar(type: Jar) { classifier "source" } publishing { publications { maven(MavenPublication) { from components.java artifacts = ["my-custom-jar.jar", sourceJar] } } }
sources
- The set of artifacts for this publication.Sets the groupId for this publication.
Sets the version for this publication.
