How to add a new component to the platform

How to add a new component to the platform

1. Add version information into versions.json as a child of core or vaadin depending on it's a core or a pro component. e.g.

"vaadin-new-component": {
    "npmName": "@vaadin/vaadin-new-component",
    "javaVersion": "1.0.0",
    "jsVersion": "1.0.0",
    "component": true,
    "pro": true
},

2. If the component has Java implementation:

   1. Add its version into scripts/generator/templates/template-vaadin-spring-bom.xml. Example:

      <dependency>
          <groupId>com.vaadin</groupId>
          <artifactId>vaadin-new-component-flow</artifactId>
          <version>${vaadin.new.component.version}</version>
      </dependency>
      

   2. Add the dependency to vaadin-core/pom.xml for core components or vaadin/pom.xml for pro components

      <dependency>
          <groupId>com.vaadin</groupId>
          <artifactId>vaadin-new-component</artifactId>
      </dependency>
      

   3. Add an IT test for the new component like others did in vaadin-platform-test.

3. Check if we need to include any information of the new component in release note: scripts/generator/templates/template-release-notes.md

4. Update README.md to include the information if needed

5. Make a PR to a correct branch (master for the latest, vX for version X, e.g. v12 for Platform 12)
