Unmarked class

Question

I am testing a . jar where I will pass named parameters on the command line, etc. The problem is that you are not finding my main class. Somebody help me?

package appOptions;

import org.apache.commons.cli.CommandLine;
import org.apache.commons.cli.CommandLineParser;
import org.apache.commons.cli.DefaultParser;
import org.apache.commons.cli.Options;
import org.apache.commons.cli.ParseException;

public class Main {

    public static void main(String[] args) throws ParseException {
        Options options = new Options();
        options.addOption("t", true, "Teste");

        CommandLineParser parser = new DefaultParser();
        CommandLine cmd = parser.parse( options, args);

        if(cmd.hasOption("t")) {
            System.out.println("Funcionou");
        }
        else {
            System.out.println("Não funcionou");
        }

    }

}

And my file pom:

            <version>1.3.1</version>
        </dependency>
    </dependencies>
</project>

I’ve changed course and nothing.

Change that:

<mainClass>com.roknauta.addOption.src.main.java.addOptions.Main</mainClass>

To:

<mainClass>appOptions.Main</mainClass>
