Dependency Management

Helidon provides a "Bill Of Materials" (BOM) to manage dependencies. This is a special Maven POM file that provides dependency management.

Using the Helidon BOM allows you to use Helidon component dependencies with a single version: the Helidon version.

Application POMs

If you created your application using the Helidon CLI or Maven archetypes, then your project will have a Helidon Application POM as its parent POM. In this case, you get Helidon's dependency management automatically.

If your project does not use a Helidon Application POM as its parent, then you must import the Helidon BOM POM.

BOM POM

To import the Helidon BOM POM, add the following snippet to your pom.xml file.

Import the Helidon BOM:

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>io.helidon</groupId>
      <artifactId>helidon-bom</artifactId>
      <version>${helidon.version}</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

Helidon Components

After you import the BOM, you can declare dependencies on Helidon components without specifying a version.

Component dependency:

<dependency>
  <groupId>io.helidon.config</groupId>
  <artifactId>helidon-config-yaml</artifactId>
</dependency>
