How can I install the Wicket framework? Please guide me!

5 small steps to a web applicationFill in the Maven coordinates for your project in the wizard and select the appropriate Wicket version. Copy the generated commandline to your clipboard and paste it in a terminal (or a DOS box) Open the project in your IDE of choice. Start the Start class in the src/test/java folder.
Wicket is a Java server-side web component-oriented framework that aims at simplifying building web interfaces by introducing patterns known from desktop UI development. With Wicket it is possible to build a web application using only Java code and XHTML compliant HTML pages.
About Apache Wicket It features a POJO data model, no XML, and a proper mark-up / logic separation not seen in most frameworks. Apache Wicket gives you a simple framework for creating powerful, reusable components and offers an object oriented methodology to web development while requiring only Java and HTML.
Meet Wicket Our technology provides customers with the tools to offer a fast, touchless, and more convenient experience for both guests and staff. With deployments at large venues, enterprises, and retail spaces across the country, Wicket has a proven facial recognition and authentication solution for any facility.
Here are step-by-step instructions I put together a few months ago for installing Wicket. They list everything I did to set Wicket up on a vanilla machine with Eclipse installed.
Unzipped maven to C:\Program Files\apache-maven-3.0.1
Updated system environment variables:
M2M2_HOMEJAVA_HOMEM2_REPO
Followed instructions at Wicket quickstart, generating this Maven command:
mvn archetype:create
-DarchetypeGroupId=org.apache.wicket
-DarchetypeArtifactId=wicket-archetype-quickstart
-DarchetypeVersion=1.4.1
-DgroupId=com.mycompany
-DartifactId=projName
Ran above Maven command from command line
mvn eclipse:eclipse to create an Eclipse project based on aboveImported project into Eclipse with File > Import..., Existing Projects
Ran Start.java in the test folder and found the test app up and running at http://localhost:8080
Optional: support for third-party code, like Wicket Extensions
Manually adding the Wicket Extensions JAR file to to the M2_REPO directory won't work.
Instead, run mvn clean dependency:copy-dependencies after updating the POM. (Wicket Extensions is included but commented out in the default POM.) Then configure the build path in Eclipse by using Add Variables... (not Add JARs), select M2_REPO, press Extend, find the desired JAR (in this case, Wicket Extensions).
A similar procedure should work for other third-party libraries.
I was originally going to keep updating this web page with more instructions, but I've been working on other things lately. Eventually, though, I hope to get around to instructions on how to configure Wicket with Tomcat instead of relying solely on the jetty server it comes with.
Instructions for deploying to Tomcat are here:
Download and install Apache Tomcat and Apache Ant.
Create the following directory structure:
\WicketTomcat
+---src
| +---main
| | +---java
| | | \---com
| | | \---HelloWicket
| | | HelloWorld.java
| | | HelloWorld.html
| | | HelloWorldApplication.java
| | \---webapp
| | \---WEB-INF
| | web.xml
| \---test
| \---java
+---lib
| junit.jar
| log4j.jar
| servlet-api.jar
| slf4j-api.jar
| slf4j-log4j.jar
| wicket.jar
| wicket-extensions.jar
+---target
build.xml
Fill in the files as follows:
HelloWorld.java
package com.HelloWicket;
import org.apache.wicket.markup.html.WebPage;
import org.apache.wicket.markup.html.basic.Label;
public class HelloWorld extends WebPage {
public HelloWorld() {
add(new Label("message", "Hello, Wicket!"));
}
}
HelloWorld.html
<html>
<head>
<title>Wicket Tomcat test title</title>
</head>
<body>
<span wicket:id="message">Message goes here</span>
</body>
</html>
HelloWorldApplication.java
package com.HelloWicket;
import org.apache.wicket.Page;
import org.apache.wicket.protocol.http.WebApplication;
public class HelloWorldApplication extends WebApplication {
public HelloWorldApplication() {
}
/**
* @see org.apache.wicket.Application#getHomePage()
*/
@Override
public Class<? extends Page> getHomePage() {
return HelloWorld.class;
}
}

As I did with the original answer, I posted a slightly more explanatory version of this answer here, but this should really be enough to get you going.

Make sure you have maven2 installed, then go to http://wicket.apache.org/start/quickstart.html, copy the command line from there and run it. That should create a project with a demo application and page that you can import in your favourite IDE and play with.
