TransformAction

Interface for artifact transform actions.

A transform action implementation is an abstract class implementing the TransformAction.transform(org.gradle.api.artifacts.transform.TransformOutputs) 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
    }
}

Implementations of TransformAction are subject to the following constraints:

Implementations can receive parameters by using annotated abstract getter methods.
