TransformAction

Interface for artifact transform actions.

A transform action implementation is an abstract class implementing the transform method. A minimal implementation may look like this:

import org.gradle.api.artifacts.transform.TransformParameters;

public abstract class MyTransform implements TransformAction<TransformParameters.None> {
    @InputArtifact
    public abstract Provider<FileSystemLocation> getInputArtifact();

    @Override
    public void transform(TransformOutputs outputs) {
        File input = getInputArtifact().get().getAsFile();
        File output = outputs.file(input.getName() + ".transformed");
        // Do something to generate output from input
    }
}

• Do not implement getParameters in your class, the method will be implemented by Gradle.
• Implementations may only have a default constructor.

• An abstract getter annotated with InputArtifact will receive the input artifact location, which is the file or directory that the transform should be applied to.
• An abstract getter with InputArtifactDependencies will receive the dependencies of its input artifact.
