To help us debug your issue fill in the basic information below using the options provided

Serverless Java Container version: 1.5

Implementations: Spring Boot 2

Framework version: SpringBoot 2.2.7.RELEASE

Frontend service: HTTP API

Deployment method: CloudFormation

Scenario

I'm trying to implement a new application using SpringBoot 2.2.7. But when I use asyncInit() i get the error Cannot resolve method 'springBootApplication' in 'ServletLambdaContainerHandlerBuilder'

                ContainerConfig lambdaContainerConfig = LambdaContainerHandler.getContainerConfig();
                lambdaContainerConfig.setInitializationTimeout(20_000);
                lambdaContainerConfig.setDefaultContentCharset(StandardCharsets.UTF_8.name());
                // For applications that take longer than 10 seconds to start, use the async builder:
                long startTime = Instant.now().toEpochMilli();
                handler = new SpringBootProxyHandlerBuilder()
                        .defaultProxy()
                        .asyncInit()
                        .springBootApplication(Application.class)         // Here I get the error Cannot resolve method 'springBootApplication' in 'ServletLambdaContainerHandlerBuilder'
                        .buildAndInitialize();

This only happens when I use version 1.5, when I downgrade to 1.4 the error stop showing.
asyncInit() returns ServletLambdaContainerHandlerBuilder on version 1.5 but on version 1.4 it returns SpringBootProxyProxyHandlerBuilder.
Furthermore, why asyncInit(Long startTime) is deprecated on version greater than 1.5?

Expected behavior

Not showing error Cannot resolve method 'springBootApplication' in 'ServletLambdaContainerHandlerBuilder'

[Intelligent2013]

I have this issue for both 1.5 and 1.5.2.

COMPILATION ERROR :

my.example.StreamLambdaHandler.java:[37,17] cannot find symbol
  symbol:   method springBootApplication(java.lang.Class<my.example.Application>)
  location: class com.amazonaws.serverless.proxy.internal.servlet.ServletLambdaContainerHandlerBuilder

From pom.xml:

        <dependency>
            <groupId>com.amazonaws.serverless</groupId>
            <artifactId>aws-serverless-java-container-spring</artifactId>
            <version>1.5.2</version>
        </dependency>

I get the source code from https://github.com/awslabs/aws-serverless-java-container/wiki/Quick-start---Spring-Boot#asynchronous-initialization
