ClassNotFoundException: org.slf4j.impl.StaticLoggerBinder

Question

I am converting a spring app to spring-boot, using boot-starter-parent version: 2.0.4.RELEASE. When I build using mvn install, its is going through fine, but when I am trying to run the app using command:mvn spring-boot:run -Dspring.profiles.active=dev, I am getting this exception: ClassNotFoundException: org.slf4j.impl.StaticLoggerBinder

Here are dependencies in my pom:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.4.RELEASE</version>
</parent>

<dependencies>
  <dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-sleuth</artifactId>
    <version>2.0.1.RELEASE</version>
  </dependency>
  <dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.24</version>
  </dependency>
  <dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.3.0-alpha4</version>
  </dependency>
  <dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-core</artifactId>
    <version>1.3.0-alpha4</version>
  </dependency>
</dependencies>

I have tried following the advice from this question, and using new and old versions of logback (both core and classic) dependencies, and adding the 'slf4j-log4j12' and 'slf4j-simple' but still getting the exception. Stack Trace is:

java.lang.NoClassDefFoundError: org/slf4j/impl/StaticLoggerBinder at org.springframework.boot.logging.logback.LogbackLoggingSystem.getLoggerContext (LogbackLoggingSystem.java:285) at org.springframework.boot.logging.logback.LogbackLoggingSystem.beforeInitialize (LogbackLoggingSystem.java:102) at org.springframework.boot.context.logging.LoggingApplicationListener.onApplicationStartingEvent (LoggingApplicationListener.java:191) at org.springframework.boot.context.logging.LoggingApplicationListener.onApplicationEvent (LoggingApplicationListener.java:170) at org.springframework.context.event.SimpleApplicationEventMulticaster.invokeListener (SimpleApplicationEventMulticaster.java:167) at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent (SimpleApplicationEventMulticaster.java:139) at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent (SimpleApplicationEventMulticaster.java:122) at org.springframework.boot.context.event.EventPublishingRunListener.starting (EventPublishingRunListener.java:68) at org.springframework.boot.SpringApplicationRunListeners.starting (SpringApplicationRunListeners.java:48) at org.springframework.boot.SpringApplication.run (SpringApplication.java:316) at org.springframework.boot.SpringApplication.run (SpringApplication.java:1258) at org.springframework.boot.SpringApplication.run (SpringApplication.java:1246) at com.hbo.esp.MyApplication.main (MyApplication.java:17) at sun.reflect.NativeMethodAccessorImpl.invoke0 (Native Method)

Try changing version of each dependency as follow.

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.25</version>
</dependency>
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.2.3</version>
</dependency>
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-core</artifactId>
    <version>1.2.3</version>
</dependency>

Hope this helps.

Had the same problem with SLF4J 1.8.0-beta4 and Logback 1.3.0-alpha4. But the above constelation works in my case, thanks! However I would appreciate an updated Logback (assuming the fault is there). – phirzel Jun 09 '19 at 19:21
@phirzel, have you solved this issue for newer versions of Logback? I [try](https://stackoverflow.com/questions/59737916/should-we-use-isdebugenabled-while-logging-calculated-data-with-logback) to use it for Slf4j **fluent API** advantages, and have now error `java.lang.NoClassDefFoundError: org/slf4j/impl/StaticLoggerBinder` on spring boot starting. Appreciates any help – Dan Brandt Jan 15 '20 at 14:42
