Build failing when including the Openshift Java RESTClient

I have a project using Spring, and as soon as I include the below in my pom.xml file:

<dependency>
<groupId>com.openshift</groupId>
<artifactId>openshift-restclient-java</artifactId>
<version>6.1.3.Final</version>
</dependency>

I get the below set of errors. Any ideas on how to fix this?

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/Users/m/.m2/repository/org/slf4j/slf4j-log4j12/1.7.25/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]

Both Spring boot and the Openshift library use slf4j, which is a logging bridge framework. However, they both include a different bindings:

  • Spring boot includes Logbback
  • Openshift includes log4j

You can fix this by excluding either one of them, for example:

<!-- language: lang-xml -->
<dependency>
    <groupId>com.openshift</groupId>
    <artifactId>openshift-restclient-java</artifactId>
    <version>6.1.3.Final</version>
    <exclusions>
        <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
        </exclusion>
    </exclusions>
</dependency>
