Google Datastore library conflict with Apache beam DatastoreIO

I am using Google Dataflow sdk

<dependency>
  <groupId>com.google.cloud.dataflow</groupId>
  <artifactId>google-cloud-dataflow-java-sdk-all</artifactId>
  <version>2.1.0</version>
</dependency>

and Google Datastore sdk

<dependency>
        <groupId>com.google.cloud</groupId>
        <artifactId>google-cloud-datastore</artifactId>
        <version>1.6.0</version>
</dependency> 

I got the following conflict when using DatastoreIO.v1().write():

java.lang.NoSuchMethodError: com.google.datastore.v1.client.DatastoreOptions$Builder.host
