GCP PUB/SUB Dependency Issue

Hi,

We are trying to integrate Google Cloud Pub/Sub feature (https://cloud.google.com/pubsub/docs/publisher#java) in AEM 6.5.11.

We added dependency in Parent and Core respectively as below:

<!-- https://mvnrepository.com/artifact/com.google.cloud/google-cloud-pubsub -->
<dependency>
<groupId>com.google.cloud</groupId>
<artifactId>google-cloud-pubsub</artifactId>
<version>1.122.2</version>
</dependency>

<!-- https://mvnrepository.com/artifact/com.google.cloud/google-cloud-pubsub -->
<dependency>
<groupId>com.google.cloud</groupId>
<artifactId>google-cloud-pubsub</artifactId>
</dependency> 

After adding dependency, Build is succesful but bundle is not active.

It gives many errors in inported sections:

NOTE: In Core POM.xml, Added entry as below in Export-package section:

Related import in JAVA:

Thanks in advance.

Regards,

KTNR
