This will be checked at the end of configuring variant configurations, as they are locked against further mutation.

If the set of attributes is shared across configurations, consider adding an additional attribute to one of the variants for the sole purpose of disambiguation.

The `filter()` method has two variants, which behave differently:

* one takes a `{javaApi}/java/io/FilterReader.html[FilterReader]` and is designed to work with Ant filters, such as `ReplaceTokens`
* one takes a closure or link:{javadocPath}/org/gradle/api/Transformer.html[Transformer] that defines the transformation for each line of the source file

Note that both variants assume the source files are text-based.

	// Used to implement field tracking; created during deadcode if
