SLF4J NoSuchMethodError on LocationAwareLogger

Question

This is a question that has been asked before, but unfortunately no solution seems to work for me. I am facing this exception (with abridged stack trace):

Answer 1

This usually happens when you have dependencies that both use the same transitive dependency. This means that 2 of your dependencies (or your app, and a transitive dependency) are both using SLF4J internally with different versions. But your app can only use a single version of the class at the same time so it has to choose (don't know the rules here... random?)

To solve the problem, you usually need to do a mvn dependency:tree to see which are using different versions of SLF4J.

Adding this dependency solved the issue for me

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.25</version>
</dependency>

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
    <version>1.7.5</version>
</dependency>

Answer 2

do

mvn clean dependency:tree -DskipTests;

remove all the dependencies of "org.slf4j" except one (highest one") as

    <dependency>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jar-plugin</artifactId>
        <version>2.6</version>
        <exclusions>
            <exclusion>
                <groupId>org.slf4j</groupId>
                <artifactId>slf4j-jdk14</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.slf4j</groupId>
                <artifactId>jcl-over-slf4j</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
