通过pom.xml执行主类

Question

Guys I know I am asking a very silly question, but I am very curious like why my test is not running.

I have created simple maven project(no junits, etc just a simple main class) with one only main class in a test folder and I am trying to execute the same through pom.xml.

I have gone through the existing question's over here but that didn't resolve it

When I try to execute it I got the following output.

Running samplemav.TestOne
Tests run: 0, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.015 sec

pom.xml

                </includes>
            </configuration>
        </plugin>

Java Class

 package samplemav;
 public class TestOne {

    public static void main(String args[]){

        System.out.println("test");
    }

}

Answer 1

I am not sure about the discussion on the question in the comments. As per my understanding you can execute the main app just fine through the mvn command. Check the below link.

Building and Running a Java SE Application by Using Maven

follow the instructions as mentioned in the documentation.

In your case the command to execute will be

mvn exec:java -Dexec.mainClass="samplemav.TestOne"

I am assuming you may not have to provide settings.xml path

You are using maven-surefire-plugin to build you app so obviously it will try to execute test project. Now because there is no classes in there it will obviously give you the output you received.

Answer 2

You may want to use Junit for unit testing.

package samplemav;
import org.junit.Test;
 public class TestOne {

    @Test
    public void test() {

        System.out.println("test");
    }

}

And add test dependency your pom.xml

<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.11</version>
  <scope>test</scope>
</dependency>
