Cucumber - Undefined Steps Though defined - selenium

Question

I'm creating a Simple Selenium Cucumber project and defined steps using "Lambda Expressions Constructor" way for a feature file but when I ran the CucumberTest class I'm getting failure exception as
There are undefined steps!
My StepDefinition is below one
And Feature file is the below one
CucumberRunner class is below:
So please suggest me is there any different approach for calling Step Definition File if I use Lambda Expressions?

As already mentioned in my comment. The option glue expects a list of package names, not directories. Changing it from
glue = {"src/test/java/my.project.automation.wolfram_alpha" }
to
glue = {"my.project.automation.wolfram_alpha" }
will solve the issue.
Find working snippets below. Assuming following structure
src/test/java/my/project/automation/wolfram_alpha/StepDef.java
src/test/java/my/project/automation/wolfram_alpha/cucumberTest.java
src/test/resources/wolfram.feature

And("login is successful" , () -> {
System.out.println("And login is successful");

And("user search for a {string}" , (String topic) -> {

wolfram.feature from the question
Running the test with mvn test produces following output.
