google cloud dataflow sdk - dependencies issue

Added the dataflow dependency to the project. The project builds , but on start up ( using jetty ) I get a runtime exception 

 <dependency>
        <groupId>com.google.cloud.dataflow</groupId>
        <artifactId>google-cloud-dataflow-java-sdk-all</artifactId>
        <version>1.9.0</version>
    </dependency>

caused by: java.lang.ClassNotFoundException: com.google.auth.http.HttpTransportFactory
at org.codehaus.plexus.classworlds.strategy.SelfFirstStrategy.loadClass(SelfFirstStrategy.java:50)
at org.codehaus.plexus.classworlds.realm.ClassRealm.unsynchronizedLoadClass(ClassRealm.java:259)
at org.codehaus.plexus.classworlds.realm.ClassRealm.loadClass(ClassRealm.java:235)
at org.codehaus.plexus.classworlds.realm.ClassRealm.loadClass(ClassRealm.java:227)
at org.eclipse.jetty.webapp.WebAppClassLoader.loadClass(WebAppClassLoader.java:487)
at org.eclipse.jetty.webapp.WebAppClassLoader.loadClass(WebAppClassLoader.java:428)

if i remove the dependency. The start up has not issues. Any idea why the dataflow dependency is causing startup error.

Added the exclusion for the conflicting dependency, and it works. 

 <dependency>
        <groupId>com.google.cloud.dataflow</groupId>
        <artifactId>google-cloud-dataflow-java-sdk-all</artifactId>
        <version>1.9.0</version>
        <exclusions>
            <exclusion>
                <groupId>com.google.auth</groupId>
                <artifactId>google-auth-library-oauth2-http</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
