For example, I want to know this SpringBootApplication class belongs to which JAR or dependency :

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

public class SpringBootWebApplication {

	public static void main(String[] args) throws Exception {, args);



In Eclipse IDE, double clicks on the class name, press CTRL + SHIFT + T (win/*nix) or CMD + SHIFT + T (mac) to prompt out a small “Open Type” window about the class detail :

This SpringBootApplication class belongs to spring-boot-autoconfigure-1.4.2.RELEASE.jar
