/**
 * Attaching this annotation to a {@link TransformAction} type it indicates that the build cache should be used for artifact transforms of this type.
 *
 * 

Only an artifact transform that produces reproducible and relocatable outputs should be marked with {@code CacheableTransform}.

* *

* Normalization must be specified for each file parameter of a cacheable transform. * For example: *

*
 * import org.gradle.api.artifacts.transform.TransformParameters;
 *
 * {@literal @}CacheableTransform
 * public abstract class MyTransform implements TransformAction<TransformParameters.None> {
 *     {@literal @}PathSensitive(PathSensitivity.NAME_ONLY)
 *     {@literal @}InputArtifact
 *     public abstract Provider<FileSystemLocation> getInputArtifact();
 *
 *     {@literal @}Classpath
 *     {@literal @}InputArtifactDependencies
 *     public abstract FileCollection getDependencies();
 *
 *     {@literal @}Override
 *     public void transform(TransformOutputs outputs) {
 *         // ...
 *     }
 * }
 * 
* * @since 5.3 */ @Retention(RetentionPolicy.RUNTIME) @Target({ElementType.TYPE}) public @interface CacheableTransform { }
