getting NoClassDefFoundError

[theonlygusti]

I am trying to use JCommander in a project,

import com.beust.jcommander.Parameter;

import com.beust.jcommander.JCommander;

public class Commander implements CommandExecutor {

  public Commander(Plugin plugin) {

    // ...

  }

  private class CommandTemplate {

    @Parameter

    private List<String> parameters = new ArrayList<>();

  }

  @Override

  public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {

    /* This section causes the error:

     * java.lang.ClassNotFoundException: com.beust.jcommander.JCommander

     */

    CommandTemplate template = new CommandTemplate();

    new JCommander(template, args);

    for (String parameter : template.parameters)

      sender.sendMessage(label);

    return true;

  }

}

I am wondering how i can fix the above code to not error out

Make sure you are importing JCommander with your build tool correctly. The doc explains how to do this with Gradle and Maven:

I aded the dependency:

<!-- from the jcenter repository, jcommander is used to parse in-game commands -->

  4     <dependency>

  3       <groupId>com.beust</groupId>

  2       <artifactId>jcommander</artifactId>

  1       <version>1.48</version>

92      </dependency>

I solved it. My maven was compiling two jars to the same location, and the one without dependencies was being loaded instead of the dependency one.
