Call Java main method after maven build process

Question

Test.java is the class that has the main method

I have added Test.java in pom.xml. So that after the maven build, the main method will be called.

Below code snippet, denotes the class name in pom.xml

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <version>1.6.0</version>
  <configuration>
    <mainClass>com.example.Test</mainClass>
  </configuration>
</plugin>

I am running the project using mvn clean install exec:java command.

As expected, Test.java is called after a successful maven build.

Is there any option to run Test.java even after maven build failure?

What about just running, mvn exec:java ? That should run your main without compiling if that is what you're asking? Although, I think using clean will remove your class files, so after a failed build there might not be enough to run. — matt, Mar 30 '21 at 12:51
at what phase did your build failed? Did you try: `mvn compile exec:java -Dexec.mainClass="com.example.Test`. In this case, you `compile` and force an execution on a specific class. If your question is how to execute the class even if the build *phase X* fails (obviously after compilation), then check `true`. — azbarcea, Mar 30 '21 at 12:52
Thanks, matt & azbarcea! After trying out both suggesstions, azbarcea soulution helped me out! Thanks for your help! :) — niranj1997, Mar 30 '21 at 13:01

Consider using Java Spring-Boot Command line runner:

@SpringBootApplication
public class SpringBootConsoleApplication 
  implements CommandLineRunner {

    private static Logger LOG = LoggerFactory
      .getLogger(SpringBootConsoleApplication.class);

    public static void main(String[] args) {
        LOG.info("STARTING THE APPLICATION");
        SpringApplication.run(SpringBootConsoleApplication.class, args);
        LOG.info("APPLICATION FINISHED");
    }
 
    @Override
    public void run(String... args) {
        LOG.info("EXECUTING : command line runner");
 
        for (int i = 0; i < args.length; ++i) {
            LOG.info("args[{}]: {}", i, args[i]);
        }
    }
}

The code in the public void run() will be called once the server started.

Thanks for your answer. But we are not using spring boot here. My only need is to run my main method after maven success (or) failure — niranj1997, Mar 30 '21 at 12:40

As per @azbarcea's comment, tried adding the following snippet to pom.xml properties

<maven.test.failure.ignore>true</maven.test.failure.ignore>

After adding the above code, Test.java is called and it is getting executed.
