Overview

A Project is the main API to use to interact with Gradle. All top level statements within a "build.gradle" build script are delegated to the corresponding Project instance and when executed, modify its state.

In case of a multi-project build, It is possible to configure a project build from another build script associated with any project in the hierarchy. This capability is called cross-project configuration. Gradle implements cross-project configuration via configuration injection. Configuration injection is the default way to define common behavior.

Project Coordinates

Gradle reads and builds artifacts that are compatible with Maven repositories, so they are described by Maven project coordinates. Project coordinates artifactId, groupId and version can be read or set in the settings configuration file via the ProjectDescriptor interface, or in the build configuration file, described by this article, via the Project interface. These details apply to single project builds and multi-project builds.

Project Name, artifactId

The project name can only be set in the initialization phase, in the settings configuration file, via the ProjectDescriptor interface. An attempt to set the project name in the configuration phase or execution phase via the Project interface, for both single/root project or sub-project will trigger a Gradle execution error.
