Solved Switch help

Hi. I'm little bit editing SkyWars plugin. When i load Game class to eclipse evrithing is ok, but switch is red lines. How i can fix it?

switch (1.$SwitchMap$vc$pvp$skywars$game$GameState[this.gameState.ordinal()]) {
case 1:
if (this.timer == 0)
onGameStart();
else if ((this.timer % 10 == 0) || (this.timer <= 5))
sendMessage(new Messaging.MessageFormatter().withPrefix().setVariable("timer", String.valueOf(this.timer)).format("game.countdown")); break;
case 2:
}
}

 

Ok. It's ok now
