Im am trying to use google cloud pubsub with actuator but when I call /actuator/health the program throws the following exeption:

Line that throws error is that, saying that method does not exists.

DefaultSubscriberFactory.java#L398

    ExecutorProvider executor = getExecutorProvider(subscriptionName);
    if (executor != null) {
      subscriberStubSettings.setBackgroundExecutorProvider(executor);
    }

I tried to modify versions of the libs without success.

Spring Boot version 2.3.1.RELEASE

    implementation 'org.springframework.integration:spring-integration-core'
    implementation platform('com.google.cloud:spring-cloud-gcp-dependencies:3.2.1')
    implementation 'com.google.cloud:spring-cloud-gcp-starter'
    implementation 'com.google.cloud:spring-cloud-gcp-starter-pubsub'

Answer 1

That's a given fact; it only uses com.google.api.gax.core.InstantiatingExecutorProvider :

See SubscriberStubSettings.java
