This style of property definition is legacy in Gradle and is discouraged:

[source,java]
----
public class MyTask extends DefaultTask {
    private String someProperty;

    public String getSomeProperty() {
        return someProperty;
    }

    public void setSomeProperty(String someProperty) {

This feature is helpful if you work with tasks provided by Gradle.

*Note* that it is still possible to pass `Task.dependsOn()` a `Provider` that returns a file and that represents a task output, for example `myTask.dependsOn(jar.archiveFile)` or `myTask.dependsOn(taskProvider.flatMap { it.outputDirectory })`, when the `Provider` is an annotated `@OutputFile` or `@OutputDirectory` property of a task.

This is done via a `Property` class type.
