I'm trying to run the GetAccountHierarchy example. It works perfectly fine when run ass part of a small example project (call it SampleProject) with the following pom.xml:

  <dependencies>
     <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-api</artifactId>
      <version>1.7.25</version>
    </dependency>    
    <dependency>
      <groupId>com.google.api-ads</groupId>
      <artifactId>ads-lib</artifactId>
      <version>4.9.1</version>
    </dependency>
    <dependency>
      <groupId>com.google.api-ads</groupId>
      <artifactId>adwords-axis</artifactId>
      <version>4.9.0</version>
    </dependency>
    <dependency>
      <groupId>com.google.api-ads</groupId>
      <artifactId>dfp-axis</artifactId>
      <version>4.9.1</version>
    </dependency>
    <dependency>
      <groupId>com.google.api-ads</groupId>
      <artifactId>google-ads</artifactId>
      <version>10.1.0</version>
    </dependency>
  </dependencies>

However, when used in a larger project (call it ProdProject -- here it is hard to isolate a reproducible case) the error in the subject appears, with the following stack trace:

java.lang.NoClassDefFoundError: com/google/api/FieldBehaviorProto
    at com.google.ads.googleads.v6.resources.CustomerClientProto.<clinit>(CustomerClientProto.java:62)
    at com.google.ads.googleads.v6.resources.CustomerClient.getDescriptor(CustomerClient.java:139)
    at com.google.ads.googleads.v6.resources.CustomerClient.hashCode(CustomerClient.java:740)
    at java.util.HashMap.hash(HashMap.java:339)
    at java.util.HashMap.put(HashMap.java:612)
    at mypkg.GetAccountHierarchy.createCustomerClientToHierarchy(GetAccountHierarchy.java:271)
    at mypkg.GetAccountHierarchy.gatherHierarchies(GetAccountHierarchy.java:124)

Because there's some formatting differences between the example [here] and as run, clarifying that GetAccountHierarchy.java:271 is

  customerClientToHierarchy.put( rootCustomerClient, customerIdsToChildAccounts );

and GetAccountHierarchy.java:124 is

         Map<CustomerClient, Multimap<Long, CustomerClient>> customerClientToHierarchy = createCustomerClientToHierarchy( seedCustomerId );

This ProdProject does not directly reference the api-ads libraries, but instead references LibProject which in turn has the following google libraries

        </dependency>

As a workaround, adding the following to the pom.xml of the ProdProject works:

            <groupId>com.google.api.grpc</groupId>
            <artifactId>proto-google-common-protos</artifactId>
            <version>2.0.1</version>
        </dependency>

However, it would be good to understand what the problem is and why the SampleProject works without this dependency.
