Question

我想在我的应用程序中使用Guice，但是当我想运行它时会抛出异常：

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

当我用try ... catch块包装main()函数时，我会收到folloving stackTrace：

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Provide方法引发的。不过它应该用Guice 4.0修复。也许有人知道如何解决它并可以提供帮助？提前谢谢！

main()功能：

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
    }
}

我使用Java 10，但也尝试了8和9.没有任何帮助。

我认为您没有使用Java 8或9，因为使用Java 10或更高版本会导致ClassReader引发异常。

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

Opcodes.V9表示Java 9.所以请再次检查Java版本并使用Java 9或更早版本运行。
