Configure test fixtures for publication

Stay organized with collections Save and categorize content based on your preferences.

Publishing test fixtures does not require any particular configuration of the publication. However, the capability mechanism used to handle fixtures requires an additional configuration.

For a given artifact with coordinates groupId:artifactId:version, Gradle expects that the test fixtures artifact declares a capability with coordinates groupId:artifactId-test-fixtures:version. This is not currently done automatically by either the test fixture support or the Maven Publish Plugin, and therefore must be done manually.

Gradle creates the capability from the project’s name, group, and version. All three must be set up to match the artifactId, groupId, and version set in the publication.

The project’s name is the last segment of its path by default; so the default name of a project with the path :path:to:mylibrary is mylibrary. If this is not what you want to use for artifactId, then you need to change your project name.

There are two options for renaming your project:

  • Rename the folder of the project. This changes the project name, or the Gradle path of the project, so all dependencies on that project need to be updated. While this might create more reorganization work initially, we recommend keeping the project name and folder the same because it reduces confusion in the long run.
  • Rename the project in Gradle without renaming the folder of the project. This avoids the impact on source versioning, but it splits the project location and name.

To rename the project in Gradle, insert the following code in the settings.gradle file:


include ':path:to:mylibrary'
project(':path:to:mylibrary').name = 'my-library'


project(":path:to:mylibrary").name = "my-library"

This code assigns the new path of the project to :path:to:my-library.

The value groupId defaults to the build name (which is generally the name of the root folder), and the value version defaults to unspecified. To change the values of group ID or version, set the group and version properties, respectively, in your project-level build.gradle file:


group = ''
version = '1.0'


group = ""
version = "1.0"
