Maven Spring Boot Failed to instantiate SLF4J LoggerFactory Reported exception:

Question

I am following the tutorial https://spring.io/guides/gs/actuator-service/

And when I try to run the App I get:

Failed to instantiate SLF4J LoggerF

Answer 1

See that message: (you manage dependency duplicate, for dependency transitive, that cause dependency duplicate with differents versions)

Class path contains multiple SLF4J bindings. SLF4J: Found binding in

make a test if use IDE Eclipse

short cut key: Shift+Ctrl+T

that way you see what file has contains this class:

SLF4J: Found binding in [jar:file:
/C:/Users/Josh/.m2/repository/ch/qos/logback/logback-classic/1.1.7/logback-classic-1.1.7.jar!
/org/slf4j/impl/StaticLoggerBinder.class]
[jar:file:/C:/Users/Josh/.m2/repository/org/slf4j/slf4j-log4j12/1.7.21/slf4j-log4j12-1.7.21.jar!
/org/slf4j/impl/StaticLoggerBinder.class]

repeat class in

slf4j-log4j12-1.7.21.jar
logback-classic-1.1.7.jar

find your same dependency and exclusion what don't you need in your project

that way:

org.seleniumhq.selenium
selenium-java
3.0.0-beta2
test

    
        xml-apis
        xml-apis
    

that one example, change for your context
