Instinct-core should either not have a mandatory requirement on fj or should list it as mandatory dependency in the pom about instinct HOT 2 OPEN

This works but fj dependency should not be visible at this level:

import com.googlecode.instinct.integrate.junit4.InstinctRunner
import com.googlecode.instinct.marker.annotate.*
import org.junit.runner.RunWith

@Grapes([
    @Grab(group='com.googlecode.instinct', module='instinct-core', version='0.1.9'),
    @Grab(group='org.functionaljava', module='fj', version='2.19')
])
@RunWith(InstinctRunner.class)
public final class AWinningGame {
    @Subject private game
    Dice winningDice

    @BeforeSpecification
    void setUp() {
        winningDice = new RiggedDice(value: 6)
        game = new Game(d1: winningDice, d2: winningDice)
    }

    @Specification
    void mustWinWhenBothDiceReturnSix() {
        println game.play() == 'win'
    }
}

interface Dice { def roll() }

class RiggedDice implements Dice {
    def value
    def roll() {
        value
    }
}

class Game {
    def d1, d2
    def play() {
        def result = (d1.roll() == 6 & d2.roll() == 6)
        result ? "win" : "lose"
    }
}

instinct-core 0.1.9 did not declare it's dependency on FJ.
instinct-core 0.2.0 does, but the repository is no longer valid.
