带有 logback 的 SLF4J 仍然提示无法加载类 “org.slf4j.impl.StaticLoggerBinder”

我有一个maven项目，它使用slf4j和logback作为记录器。我可以看到这两个项目都在我的maven依赖项树项中。但是每当我尝试运行我的项目时，我都会收到提示：

SLF4J：无法加载类“org.slf4j.impl.StaticLoggerBinder”。SLF4J：默认为无操作 （NOP） 记录器实现 SLF4J：有关更多详细信息，请参阅 http://www.slf4j.org/codes.html#StaticLoggerBinder。

我检查了链接，它说：

在类路径上放置一个（并且只有一个）slf4j-nop.jar，slf4j-simple.jar slf4j-log4j12.jar，slf4j-jdk14.jar或logback-classic.jar应该可以解决问题。

我已将 logback-classic 添加到我的项目中（我使用的是 1.0.9），但我一直收到提示，并且我的日志没有运行。

任何人都可以帮我解决这个问题吗？谢谢。

我如何在我的程序中使用它：

public class SolutionBusiness {
    protected final transient Logger logger = LoggerFactory.getLogger(getClass());

// some other codes

public void doMove(Move move) {
        if (solver.isSolving()) {
            logger.error("Not doing user move ({}) because the solver is solving.", move);
            return;
        }
        if (!move.isMoveDoable(guiScoreDirector)) {
            logger.warn("Not doing user move ({}) because it is not doable.", move);
            return;
        }
        logger.info("Doing user move ({}).", move);
        move.doMove(guiScoreDirector);
    }
}

这是我的 maven 依赖项：
