Spring Cloud AWS's AwsSecretsManagerBootstrapConfiguration is not getting processed - spring-boot

Question

For some reason, AwsSecretsManagerBootstrapConfiguration is not getting processed in my application.
Here are the annotations on AwsSecretsManagerBootstrapConfiguration:
#Configuration(proxyBeanMethods = false)
#EnableConfigurationProperties(AwsSecretsManagerProperties.class)
#ConditionalOnClass({ AWSSecretsManager.class, AwsSecretsManagerPropertySourceLocator.class })
#ConditionalOnProperty(prefix = AwsSecretsManagerProperties.CONFIG_PREFIX, name = "enabled", matchIfMissing = true)
public class AwsSecretsManagerBootstrapConfiguration {
All the conditions are satisfied, yet this configuration class is not processed and none of:
AwsSecretsManagerPropertySourceLocator
AWSSecretsManager
beans are created.
Here's my project's POM file:

And here's the application.yaml file:
cloud:
aws:
region:
static: ap-southeast-2
Main class:
package com.example.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, "--debug");
}
}
and a command line runner:
package com.example.demo;
import com.amazonaws.services.secretsmanager.AWSSecretsManager;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.stereotype.Component;
#Component
public class DemoRunner implements CommandLineRunner {
#Autowired
private AWSSecretsManager secretsManager;
#Override
public void run(String... args) throws Exception {
System.out.println("secretsManager = " + secretsManager);
}
}
When I run the program, Spring cannot resolve AWSSecretsManager:
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.amazonaws.services.secretsmanager.AWSSecretsManager' available: expected at least 1 bean which qualifies as autowire candidate.

as well as adding these properties to bootstrap.yml:
spring:
application:
name: demo
aws:
secretsmanager:
enabled: true
fail-fast: true
region: ap-southeast-2

Answer 2

Since spring-cloud-aws version 2.3 you have two options.
First - use spring.config.import property.
e.g
spring.config.import=optional:aws-secretsmanager:
This property make importing parameters based on spring.application.name property value for each active profile.
For possible configurations you can get more details in the end of this section
The second is add the dependency:
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bootstrap</artifactId>
<version>${spring-cloud.version}</version>
to enable bootstrap. And then you can configure secret manager via bootstrap properties.
