I am getting the error found in the title when I try to run my project. I have read other threads on this error, and found a solution that got rid of the error, but killed all my logging.

<exclusions>
    <exclusion>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-logging</artifactId>
    </exclusion>
</exclusions>

and

<exclusions>
    <exclusion>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
    </exclusion>
</exclusions>

both serve to rid me of the error and kill my logging. I would rather be able to keep my Spring-Boot logging and resolve this problem, but haven't been able to find a solution. Is there a way I can keep my current logging and resolve this dependency issue? What is the best way to track down the offending module?

The full error is:

Exception in thread "main" java.lang.IllegalArgumentException: LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback or the competing implementation (class org.slf4j.impl.Log4jLoggerFactory loaded from file:/C:/Users/me/.m2/repository/org/slf4j/slf4j-log4j12/1.6.4/slf4j-log4j12-1.6.4.jar). If you are using WebLogic you will need to add 'org.slf4j' to prefer-application-packages in WEB-INF/weblogic.xml: org.slf4j.impl.Log4jLoggerFactory
