[TIP]
====
`Quarkus.run` also provides a version that allows the code to handle errors.
For example:

[source,java]
----
package com.acme;

import io.quarkus.runtime.Quarkus;
import io.quarkus.runtime.QuarkusApplication;
import io.quarkus.runtime.annotations.QuarkusMain;

@QuarkusMain
public class Main {
public static void main(String... args) {
Quarkus.run(MyApp.class,
(exitCode, exception) -> {
// do whatever
},
args);
}

public static class MyApp implements QuarkusApplication {

@Override
public int run(String... args) throws Exception {
System.out.println("Do startup logic here");
Quarkus.waitForExit();
return 0;
}
}
