# Package-level declarations

Provides classes, interfaces and annotations for registering and implementing artifact transforms.

To register an artifact transform, use registerTransform. This allows you to register a org.gradle.api.artifacts.transform.TransformAction using org.gradle.api.artifacts.transform.TransformSpec.

If you want to create a new artifact transform action, have a look at org.gradle.api.artifacts.transform.TransformAction.
