==== Deprecated `Project.buildDir` is to be replaced by `Project.layout.buildDirectory`

The `Project.buildDir` property is deprecated.
It uses eager APIs and has ordering issues if the value is read in build logic and then later modified.
It could result in outputs ending up in different locations.

    // In the future StartParameter should be replaced with a `record` so this doesn't need to be checked

        def fieldNames = StartParameter.class.getDeclaredFields()
            .findAll { !it.synthetic }
            .collect { it.name }
            .toSet()
