I'm using the example stated in the manual. If you need to achieve the following output, you can do so with the code provided. Let me know if you need anything more specific. 

<pre><code>Input: java -jar &lt;your-jar&gt; hello -u conor
Output: Hello conor
</code></pre>

I'm not sure which version of dropwizard you're using. This one's for 0.9.1

Main Class

<pre><code>public class MyApplication extends Application&lt;MyConfiguration&gt; {
 public static void main(String[] args) throws Exception {
 {
 new MyApplication().run(args);
 }
 }

 @Override
 public void initialize(Bootstrap&lt;DropwizardConfiguration&gt; bootstrap) {
 bootstrap.addCommand(new MyCommand());
 }

 @Override
 public void run(ExampleConfiguration config,
 Environment environment) {
 }
}
</code></pre>

<code>MyCommand.java</code>

<pre><code>public class MyCommand extends Command {
 public MyCommand() { 
 super("hello", "Prints a greeting");
 }

 @Override
 public void configure(Subparser subparser) {
 // Add a command line option
 subparser.addArgument("-u", "--user")
 .dest("user")
 .type(String.class)
 .required(true)
 .help("The user of the program");
 }

 @Override
 public void run(Bootstrap&lt;?&gt; bootstrap, Namespace namespace) throws Exception {
 System.out.println("Hello " + namespace.getString("user"));
 }
}
</code></pre>

}

Run the code: commandName -ct dwizard as args 
Output: command to test -> dwizard

If you have written a class which extends "Command" class or similar, then the following command should work
commandName {command} {command arg}

I am trying to get my Dropwizard application to accept custom command line arguments. The documentation seems to fall short and only half explains what to do. Considering I am new to this I need a very clear example from code to command line usage.

Would anybody care to share? I have viewed <a href="https://stackoverflow.com/questions/22106508/how-to-register-add-a-command-in-dropwizard">this</a> question but it doesn't explain clearly and I can't get it to work.

Please don't ask for code samples about what I have tried. Trust me I have tried a lot and i'm not sure exactly what to post as most of the code is gone. If you know how to do this it shouldn't take long to answer. Thanks.

我正在尝试让我的Dropwizard应用程序接受自定义命令行参数。文档似乎还不够完善，只有一半的内容解释了该怎么做。考虑到我是新手，我需要一个从代码到命令行用法的非常清晰的示例。有人愿意分享一下吗？我已经查看了问题，但它没有解释清楚，我无法让它工作。请不要我已经尝试过的代码样本。相信我，我已经尝试了很多，但我不确定要发...
