The Open Liberty 18.0.0.2 features are available on Maven Central under the io.openliberty.features groupId. When features are listed as dependencies, they will be installed by the Maven or Gradle plugin as well as provide Liberty API, SPI, and Java specification dependencies for compilation. Features can also continue to be listed as before in the plugin configuration/attributes or in the server.xml file, in which case those features will also be retrieved from Maven Central for installation. As with all Maven dependencies, the features that are retrieved from Maven or Gradle will be stored locally allowing for offline builds.
