Maven spring boot未能实例化SLF4J LoggerFactory报告的异常：

Question

我正在学习https://spring.io/guides/gs/acture-service/教程

当我尝试运行应用程序时，我得到：

无法实例化SLF4J LoggerFactory报告的异常：Java.lang.NoClassDeffounderRror：ch/qos/logback/core/joran/spi/joranException at org.SLF4J.LoggerFactory.bind（LoggerFactory.Java:150)at org.SLF4J.LoggerFactory.Performitialization（LoggerFactory.Java:124)at org.SLF4J.LoggerFactory.getIloggerFactory（LoggerFactory.getIloggerFactory（在sun.misc.launcher$AppClassLoader.LoadClass（launcher.Java:331)在Java.lang.ClassLoader.LoadClass（classLoader.Java:357)...9线程“main”中的更多异常Java.lang.noClassdeffounderror：ch/qos/logback/core/joran/spi/joranexception在org.slf4j.loggerFactory.bind（loggerFactory.Java:150)在oader.findClass(URLClassLoader.java:381)在java.lang.ClassLoader.LoadClass（ClassLoader.java:424)在sun.misc.launcher$AppClassLoader.LoadClass（Launcher.java:331)在java.lang.ClassLoader.LoadClass（ClassLoader.java:357)...9其他

我的pom文件是这样的：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
  </build>

</project>

我不知道如何解决这个问题。我试着清理和重建，甚至重新进口。我看过类似的问题，但似乎没有什么有用的。

使程序运行的唯一方法是将父pom更改为1.3.1.release版本，但我不想使用此版本，而想使用1.4.1.release

如有任何帮助，将不胜感激。

如果我加上

<dependency>
  <groupId>org.slf4j</groupId>

我得到了

Answer 1

下面的行动对我有效

1. 运行MVN dependency:purge-local-repository删除所有依赖项并强制重新下载。
2. 然后执行MVN清洁验证
