Guice导致抛出UncaughtExceptionHandler

Question

我想在我的应用程序中使用Guice，但当我想要运行它时，它会抛出以下异常：

Exception in thread "main" 
Exception: com.google.common.util.concurrent.UncheckedExecutionException thrown from the UncaughtExceptionHandler in thread "main"

当我用try包装main()函数时...catch块我收到folloving：

从信息中我发现这个异常是由包含lambda定义的方法引起的，是由Provides方法抛出的。然而，它应该在Guice 4.0中修复。也许有人知道如何修复它，并能提供帮助？提前感谢！

main()函数：

public static void main (String[] args){
    try{
        MainModule module = new MainModule();
        Injector injector = Guice.createInjector(module);

        GameFactory gameFactory = injector.getInstance(GameFactory.class);
        DeckFactory blackjackDeckFactory = injector.getInstance(BlackjackDeckCreator.class);
        PlayerFactory playerFactory = injector.getInstance(PlayerFactory.class);

        Player player = playerFactory.createPlayer("Paul");
        Player dealer = playerFactory.createPlayer("Dealer", true);

        Deck deck = blackjackDeckFactory.createDeck();

        Game game = gameFactory.createGame(player, dealer, deck);
        game.start();
    } catch (Exception e){
        e.printStackTrace(); // line 31
    }
}

我用的是Java10，但也试过8和9，什么都没用。

我认为您没有使用Java8或9，因为由于使用Java10或更高版本，所以从ClassReader抛出了异常。

https://gitlab.ow2.org/asm/asm/blob/f7f44a8e306dd2bd70f0db50194f6366938579c5/src/org/objectweb/asm/ClassReader.java#L160

Opcodes.V9的意思是Java9。所以请再次检查您的Java版本，并在Java9或更早的版本上运行。

我知道这是一个老帖子。在这里发布解决方案以获得可见性-

问题应该是与GoogleGuice 4.0的JDK11不兼容。

Guice 4.0不支持Java 9(或更高版本)，但Guice 4.2支持。因此，您应该在GoogleGuice-4.2上添加一个显式依赖项，一切都应该正常工作！
