org.gradle.api.publish.PublishingExtension

The configuration of how to “publish” the different components of a project.

This new publishing mechanism will eventually replace the current mechanism of upload tasks and configurations. At this time, it is an incubating feature and under development.

The PublishingExtension is a {@link org.gradle.api.plugins.DeferredConfigurable} model element, meaning that extension will be configured as late as possible in the build.So any 'publishing' configuration blocks are not evaluated until either:

The project is about to execute, or
he publishing extension is referenced as an instance, as opposed to via a configuration closure.

A 'publishing' configuration block does not need to dereference the publishing extension, and so will be evaluated late. eg:

 publishing { publications { ... } repositories.maven { ... } }

Any use that accesses the publishing extension as an instance does require the publishing extension to be realised, forcing all configuration blocks to be evaluated. eg:

 publishing.publications { ... } publishing.repositories.maven { ... }
