Gradle dependency problem with spark

[kant kodali]

Hi Guys,

Here is the simplified version of my problem. I have the following problem
and I new to gradle


dependencies {
    compile group: 'org.apache.spark', name: 'spark-core_2.11', version: '2.0.2'
    compile group: 'com.github.brainlag', name: 'nsq-client', version:
'1.0.0.RC2'
}


I took out the other dependencies for simplicity. The problem here
is spark-core_2.11 uses com.google.guava:14.0.1 and nsq-client uses
com.google.guava:19.0 so when I submit my fat uber jar using spark-submit I
get the following error

Exception in thread "main" java.lang.NoSuchMethodError:
com.google.common.collect.Sets.newConcurrentHashSet()Ljava/util/Set;
    at com.github.brainlag.nsq.NSQProducer.(NSQProducer.java:22)
    at com.hello.streamprocessing.app.SparkDriver2.main(SparkDriver2.java:37)


any help would be great. Also if you need more description you can find it
