Symbiotic Dependencies​

With prime-core 2025.0.0, expansion-resources can define symbiotic dependencies. These dependencies are not included automatically, but only in case a number of other expansion-resources are present. This allows expander developers to create resources that provide integration with other expander beams.

How it works​

Several expander projects have 1 goal, but multiple expansion-resources. This setup exists to support integration with specific use-cases without introducing hard dependencies.

E.g. enum-type-expanders has separate resources for integration with angular and rest.

  • net.democritus.experimental.enumtypes:enum-type-expanders
  • net.democritus.experimental.enumtypes:enum-type-rest-expanders
  • net.democritus.experimental.enumtypes:enum-type-angular-expanders

However, this means that the expansionSettings become more complex:

<expansionSettings>
  <expansionResources>
    <expansionResource name="net.democritus:angular-svcapi-stack" version="1.4.0"/>
    <expansionResource name="net.democritus.experimental.enumtypes:enum-type-expanders" version="0.4.2"/>
    <expansionResource name="net.democritus.experimental.enumtypes:enum-type-rest-expanders" version="0.4.2"/>
    <expansionResource name="net.democritus.experimental.enumtypes:enum-type-angular-expanders" version="0.4.2"/>
  </expansionResources>
</expansionSettings>

Symbiotic dependencies are only included if all of their dependencies are included by other expansion-resources.

In this case, an enum-type-beam expansion-resource can add enum-type-rest-expanders and enum-type-angular-expanders as symbiotic dependencies. When used with rest-expanders, enum-type-rest-expanders will be included. When used with angular-expanders, enum-type-angular-expanders will be included.

Usage​

info

Requires expanders-maven-plugin 2025.1.0 or newer.

To create a symbiotic dependency, add the dependency to your maven pom.xml. Then, configure the dependency in the expanders-maven-plugin configuration.

<plugin>
  <groupId>net.democritus.maven.plugins</groupId>
  <artifactId>expanders-maven-plugin</artifactId>
  <executions>
    <execution>
      <goals>
        <goal>expansionResource</goal>
      </goals>
      <configuration>
        <symbioticDependencies>
          <dependency>
            <groupId>net.democritus.experimental.enumtypes</groupId>
            <artifactId>enum-type-angular-expanders</artifactId>
          </dependency>
          <dependency>
            <groupId>net.democritus.experimental.enumtypes</groupId>
            <artifactId>enum-type-rest-expanders</artifactId>
          </dependency>
        </symbioticDependencies>
      </configuration>
    </execution>
  </executions>
</plugin>
