SpringBoot application shuts down when running using JAR, but works well when running from cmd or VSCode


I am trying to run a SpringBoot application from a JAR file, which I have built using VSCode's Project Manager from Java.

The app runs smoothly when running from VSCode, or when running from the command line, using

mvn spring-boot:run

This is my Main Class file:

package com.jvc.interconnectingflights.app;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@ComponentScan("com.jvc.interconnectingflights")
public class InterconnectingFlightsApplication {
    public static void main(String[] args) {
        SpringApplication.run(InterconnectingFlightsApplication.class, args);
    }

}

This is my pom.xml file:

            </plugin>
        </plugins>
    </build>

</project>

This is the output I am getting when running from the JAR:

22:05:28.287 [main] INFO com.jvc.interconnectingflights.app.InterconnectingFlightsApplication - Started InterconnectingFlightsApplication in 3.102 seconds (process running for 3.46)

I have tried all the answers from related posts, but still no luck. I would really appreciate any advice!

Solution

  • Created a new JAR using mvn package, which turned out to work. VSCode's Java Project Manager doesn't seem to build the JAR correctly
