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 (MavenPublication.from()
.
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 MavenPublication.artifact()
and MavenPublication.artifact()
methods.
You can also completely replace the set of published artifacts using MavenPublication.setArtifacts()
.
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 MavenPublication.getPom()
method, or directly by an action (or closure) passed into MavenPublication.pom()
.
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') } } } }

String
artifactId
Note: This property is incubating and may change in a future version of Gradle.
The artifactId for this publication.
MavenArtifactSet
artifacts
Note: This property is incubating and may change in a future version of Gradle.
The complete set of artifacts for this publication.
String
groupId
Note: This property is incubating and may change in a future version of Gradle.
The groupId for this publication.
MavenPom
pom
(read-only)
Note: This property is incubating and may change in a future version of Gradle.
The POM that will be published.
String
version
Note: This property is incubating and may change in a future version of Gradle.
The version for this publication.
MavenArtifact
artifact
(Object
source)
Note: This method is incubating and may change in a future version of Gradle.
Creates a custom MavenArtifact
to be included in the publication.
The artifact
method can take a variety of input:
- A
PublishArtifact
instance. Extension and classifier values are taken from the wrapped instance. - An
AbstractArchiveTask
instance. Extension and classifier values are taken from the wrapped instance. - Anything that can be resolved to a
File
via theProject.file()
method. Extension and classifier values are interpolated from the file name. - A
Map
that contains a 'source' entry that can be resolved as any of the other input types, including file. This map can contain a 'classifier' and an 'extension' entry to further configure the constructed artifact.
The following example demonstrates the addition of various custom artifacts.
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' } } }
MavenArtifact
artifact
(Object
source, Action
<? super MavenArtifact
>
config)
Action
<? super MavenArtifact
>Note: This method is incubating and may change in a future version of Gradle.
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 MavenPublication.artifact()
.
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" } } } }
void
from
(SoftwareComponent
component)
Note: This method is incubating and may change in a future version of Gradle.
Provides the software component that should be published.
- Any artifacts declared by the component will be included in the publication.
- The dependencies declared by the component will be included in the published meta-data.
Currently 2 types of component are supported: 'components.java' (added by the JavaPlugin) and 'components.web' (added by the WarPlugin). For any individual MavenPublication, only a single component can be provided in this way. The following example demonstrates how to publish the 'java' component to a Maven repository.
apply plugin: "java" apply plugin: "maven-publish" publishing { publications { maven(MavenPublication) { from components.java } } }
Note: This method is incubating and may change in a future version of Gradle.
Configures the POM that will be published.
The supplied action will be executed against the MavenPublication.getPom()
result. This method also accepts a closure argument, by type coercion.
void
setArtifacts
(Iterable
<?>
sources)
Iterable
<?>Note: This method is incubating and may change in a future version of Gradle.
Clears any previously added artifacts from MavenPublication.getArtifacts()
and creates artifacts from the specified sources.
Each supplied source is interpreted as per MavenPublication.artifact()
.
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] } } }
