5 minutes Introduction

This session teaches you how to build your first Uberfire App in just 5 minutes.

Prerequisites

This guide assumes you have the following software set up and working on your computer:

• A Java Development Kit (JDK) version 8 or newer.

Microsoft Windows users: be sure to use a 64-bit version of the JDK because Uberfire requires more heap space than can be addressed by a 32-bit VM.

• Maven 3.x

Creating your first App

In a command line, run the archetype to create your first app.

 mvn archetype:generate -B \
-DarchetypeGroupId=org.uberfire \
-DarchetypeArtifactId=uberfire-project-archetype \
-DarchetypeVersion=1.0.0.Beta1 \
-DgroupId=org.uberfire \
-DartifactId=demo \
-Dversion=1.0-SNAPSHOT \
-Dpackage=org.uberfire \
-DcapitalizedRootArtifactId=Demo

Run it and then you should see the message:

[INFO] ---------------------------------------------------------

To build your first app, go to directory demo, build the project in maven and wait for the build to finish.

$ cd demo
$ mvn clean install

$ cd demo-showcase/demo-webapp
$ mvn clean gwt:run

Wait for GWT console build your app:

Click on "Launch Default Browser" to open your Uberfire App. Log in with the username "admin" and the password "admin". You should see our Hello World screen!

After you see that Hello World, you'll soon be able to taste the power of Uberfire.
