log4j-slf4j-impl cannot be present with log4j-to-slf4j --- after adding graphql dependency to pom

Question

Im trying mess around with graph ql and integrating it with our existing project. Im following this tutorial since our project is java with spring framework

but after adding the dependencies

<dependency>
    <groupId>com.graphql-java</groupId>
    <artifactId>graphql-spring-boot-starter</artifactId>
    <version>5.0.2</version>
</dependency>
<dependency>
    <groupId>com.graphql-java</groupId>
    <artifactId>graphql-java-tools</artifactId>
    <version>5.2.4</version>
</dependency>

and trying to start my project i get an error

Caused by: org.apache.logging.log4j.LoggingException: log4j-slf4j-impl cannot be present with log4j-to-slf4j

I have found similar post here, and here Which lead me to attempt to add exclusions but that did NOT help

        <dependency>
            <groupId>com.graphql-java</groupId>
            <artifactId>graphql-spring-boot-starter</artifactId>
            <version>5.0.2</version>
        <exclusions>
            <exclusion>
                <groupId>log4j-slf4j-impl</groupId>
                <artifactId>*</artifactId>
            </exclusion>
            <exclusion>
                <groupId>log4j-to-slf4j</groupId>
                <artifactId>*</artifactId>
            </exclusion>
        </exclusions>
        </dependency>

Excluded dependencies groupId seems wrong. Changing excluded groupId's to org.apache.logging.log4j may solve your problem.

i ended up using

<dependency>
    <groupId>com.graphql-java</groupId>
    <artifactId>graphql-java</artifactId>
    <version>5.0.2</version>
</dependency>
