In your case unirest-java has a transitive dependency on org.apache.httpcomponents, which further has a transitive dependency on commons-logging. Spring JCL probably scans the classpath, finds commons-logging and that's why it warns you about potential conflicts with Spring Boot's pre-configured loggers.

You can list all the dependencies and transitive dependencies in your Maven project by running mvn dependency:tree. For Gradle projects you can run gradle dependencies.

To exclude commons-logging in a Maven project, add this to your pom.xml configuration file:

<dependencies>
    <dependency>
        <groupId>com.mashape.unirest</groupId>
        <artifactId>unirest-java</artifactId>
        <version>1.4.9</version>
        <exclusions>
            <exclusion>
                <groupId>commons-logging</groupId>
                <artifactId>commons-logging</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
</dependencies>

If you're using Gradle, add this to your build.gradle file:

implementation('com.mashape.unirest:unirest-java:1.4.9') {
        exclude group: 'commons-logging', module: 'commons-logging'
    }

You may also exclude dependencies globally from your project:

configurations {
    compileOnly {
        extendsFrom annotationProcessor
    }
    all {
        exclude group: 'commons-logging', module: 'commons-logging'
    }
}

I would use configureEach instead of all in Gradle (new Tasks API).

For Gradle I solved it with:

configurations.implementation {
    exclude group: 'commons-logging', module: 'commons-logging'
}

in build.gradle file.

I was too lazy to exclude this dependency manually one by one, so this is how I fixed this using Gradle in a more efficient way. Just put below in your Gradle config to exclude this transitive dependency (so that only spring-jcl is used at runtime).

For build.gradle.kts:

configurations {
    runtimeOnly {
        exclude(group = "commons-logging", module = "commons-logging")
    }
}

Or, if you use build.gradle / groovy syntax:

configurations {
    runtime {
        exclude(group = "org.slf4j", module = "slf4j-log4j12")
    }
}

Neither runtime nor runtimeOnly worked for me. I had to use all or configureEach.

For the same problem with eureka updated to spring boot 3.2.5 I solved excluding commons-logging in pom.xml in this dependency

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
    <exclusions>
        <exclusion>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
        </exclusion>
    </exclusions>
</dependency>

after doing in terminal

 mvn dependency:tree

For the same problem, inside the pom i solved it like this :

<dependency>
    <groupId>org.springframework.boot</groupId>.
    <artifactId>spring-boot-starter</artifactId>
</dependency>

Let me know if it works for you too, thank you.

OP's post states that they are using spring boot which is part of the problem. So adding a spring boot dependency is pointless as it is already there.
