Problems with logging dependencies

[jusabatier]

I use LOG4J2 for logging in my SPring Boot project.

When I add print-lib as a dependency for the project, it replace Log4J binding by Logback one.

Also the SLF4J dependencies are not the same versions as the last Spring Boot ones, so I have to exclude them if I don't want the JVM to complains about duplicate versions.

To resolve those problems, I have to do some exclusions in the pom.xml :

<dependency>
    <groupId>org.mapfish.print</groupId>
    <artifactId>print-lib</artifactId>
    <version>3.29.4</version>
    <exclusions>
        <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>*</artifactId>
        </exclusion>
        <exclusion>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-classic</artifactId>
        </exclusion>
    </exclusions>
</dependency>

I think a library should not add logging dependencies when used, is it right ?
