Getting Started with Vaadin 14

App starters

The best way to get started with Vaadin 14 is to go to https://vaadin.com/start and pick an app template for the technology stack you’re interested in.

Maven Archetypes

Maven is the de-facto build tool for Java web applications. Major IDEs also support Maven out of the box and most often you'll be using Maven via your favorite IDE. There is currently one Maven archetype available, the vaadin-archetype-application which corresponds to the project base for Flow. The version of the archetype should match the platform version. After you have Maven installed, you can quickly create and run a Vaadin app with the following command:

mvn -B archetype:generate \
                -DarchetypeGroupId=com.vaadin \
                -DarchetypeArtifactId=vaadin-archetype-application \
                -DarchetypeVersion=14.0.4\
                -DgroupId=org.test \
                -DartifactId=vaadin-app \
                -Dversion=1.0-SNAPSHOT \
                && cd vaadin-app \
                && mvn package jetty:run

Manually changing Vaadin version for Java projects

    <artifactId>vaadin-bom</artifactId>

    <type>pom</type>
    <scope>import</scope>

Reporting Issues

We appreciate if you try to find the most relevant repository to report the issue in. If it is not obvious which project to add issues to, you are always welcome to report any issue at https://github.com/vaadin/platform/issues.

A few rules of thumb will help you and us in finding the correct repository for the issue:

  1. If you encounter an issue when using the HTML/JS API of a component or the component renders incorrectly, the problem is likely in the web component. The web component repositories are named like https://github.com/vaadin/vaadin-button
  2. If you encounter an issue when using the Java API of a component, the problem is likely in the Flow integration of the web component. The Flow component integration repositories are named like https://github.com/vaadin/vaadin-button-flow
  3. If you encounter an issue with Flow which does not seem to be related to a specific component, the problem is likely in Flow itself. The Flow repository is https://github.com/vaadin/flow
  4. If you encounter an issue with Designer, the repository is https://github.com/vaadin/designer
  5. If you encounter an issue with TestBench, the repository is https://github.com/vaadin/testbench
