Eclipse JKube 1.14 is now available!

On behalf of the Eclipse JKube team and everyone who has contributed, I'm happy to announce that Eclipse JKube 1.14.0 has been released and is now available from Maven Central 🎉.

Thanks to all of you who have contributed with issue reports, pull requests, feedback, and spreading the word with blogs, videos, comments, and so on. We really appreciate your help, keep it up!

What's new?

Without further ado, let's have a look at the most significant updates:

• Gradle 8 support
• Helidon support
• Spring Boot layered jar
• Helm push support for OCI registries
• 🐛 Many other bug-fixes and minor improvements

Gradle 8 support

Gradle 8 wasn't fully supported in previous versions of JKube, as some users have reported. This release fixes the issues and adds full support for Gradle 8.

Gradle 8 brings multiple improvements and new features. You can find more information in the Gradle 8 release announcement. These are some of the most relevant changes:

• Performance Boosts:
  • Introduction of a configuration cache to speed up project configuration.
  • Enhanced parallelism for task execution without requiring the '--parallel' flag.
  • Faster Java compilation with improved incremental compilation.
• Usability Improvements:
  • Improved Java toolchain support for specifying the project's JDK and vendor.
  • Introduction of Test Suites for simplifying test organization.
  • Version catalogs for managing dependencies with better plugin version support.
• Ecosystem Support Upgrades:
  • Support for Java 17 through 19, Groovy 4.0, and an updated Scala Zinc version.

Our JKube fix will allow you to take advantage of all these improvements and won't hold you back from upgrading to Gradle 8 🚀.

Helidon support

Helidon is a collection of Java libraries for writing microservices that run on a fast web core powered by Netty. Until now, if you wanted to use JKube with Helidon, you had to provide a complete image configuration.

This JKube release includes a new Helidon Generator and Enricher that will allow you to build and deploy your Helidon application to Kubernetes and OpenShift without any additional configuration.

You will find quickstarts for both Helidon SE and Helidon MP in our main repository.

Spring Boot layered jar

Spring Boot 2.3 introduced a new layered jar format to package your application. Being able to provide different layers when building your image allows you to take advantage of the Docker or Jib layer cache and reduce the image build time.

With this release, JKube will automatically detect if your project is using a layered jar and will configure the image build accordingly to take advantage of the layers defined in your jar. As usual with many of JKube's features, everything will work out of the box without any additional configuration from your side.

Using this release

If your project is based on Maven, you just need to add the Kubernetes Maven plugin or the OpenShift Maven plugin to your plugin dependencies:

<plugin>
  <groupId>org.eclipse.jkube</groupId>
  <artifactId>kubernetes-maven-plugin</artifactId>
  <version>1.14.0</version>
</plugin>

If your project is based on Gradle, you just need to add the Kubernetes Gradle plugin or the OpenShift Gradle plugin to your plugin dependencies:

plugins {
  id 'org.eclipse.jkube.kubernetes' version '1.14.0'
}
