Gradle automatically makes the properties of a task final when the task starts execution.

The link:{javadocPath}/org/gradle/api/provider/HasConfigurableValue.html#finalizeValueOnRead--[finalizeValueOnRead()] method is similar, except that the property's final value is not calculated until the value of the property is queried.

```
modifiedFiles.finalizeValueOnRead()
```
