In allure report unable to see logger statements put inside #Step annotated method - allure

Question

I am doing POC on allure reporting.I created a Gradle project that has a test class with two #Test annotated methods.The same test class has #Step annotated method that has logger statements.This #Step annotated method is called from one of the #Test annotated methods.Upon running the tests,I do not see the logger info(present under #Step method) in allure result.
I have added needed dependencies and plugin in build.gradle.
content of build.gradle file.

allure {
version = '2.8.1'
autoconfigure = true
aspectjweaver = true
useTestNG {
version = '2.0-BETA20'
}
}
my sample test code:
public class SampleTestForAllureReport {
public static Logger logger = LoggerFactory.getLogger(SampleTestForAllureReport.class);
#Severity(SeverityLevel.BLOCKER)
#Description("This is a sample test for printing welcome")
#Test()
public void welcomeEvent()
{
loggingSteps();
System.out.println("WELCOME");
}
#Test()
public void exitEvent()
{
System.out.println("EXIT");
}
#Step("logger for welcome test")
public void loggingSteps()
{
logger.info("log for step1");
}
}
allure result.
