Walking through the Eclipse IDE tooling support for new Java versions

Java language has been evolving at a fast pace with the six month release cadence and preview features. These Language features will be discussed in detail in the talk "What's new in Java?".Eclipse IDE provides a list of UI features built on top of this Java language support. Hence, Eclipse IDE also needs to keep pace with the new Java release cycle with support added in UI for the new features- both standard and preview. These Java 16 and 17 features would include Records, Pattern InstanceOf, Sealed Types, Local Interfaces/Enums and Pattern Matching for Switch .

What's New in Java?

Manoj Palat (IBM)

Java 17 is an important milestone since this is slated as a long term support (LTS) release. Apart from this designation, more importantly, it is in Java 17 that we are starting to glimpse how the building blocks of earlier releases glue together to provide the pattern programming paradigms. Essentially, the "why" a particular feature/building block exists questions start finding the answers in this version. And this indeed is a huge step for Java as well as Java programmers.

What's New in JDT?

Jeff Johnston (Red Hat, Inc.)

The JDT will have had four new releases since last fall's EclipseCon. This session will discuss the various new JDT features that have been added since then with emphasis on enhancements that aren't introduced as part of support for new Java language features. Such features include new cleanup/quick fixes, enhanced completion support, formatting, and debug enhancements.

The session will include live demos including relevant code samples.

Taming the Hydra: The Labors with Multi-Release JAR Files

Werner Keil (Self Employed)

Otavio Santana (Zup Innovation)

Although Multi-Release JAR files were introduced with Java 9 at the same time as Jigsaw (JPMS), this feature has been overshadowed by others, especially Jigsaw, JShell or even the Platform Logging API. This could be part of the reason why most of the popular build tools and also major IDEs don't really support it out of the box even more than 3 years after it was introduced. A lack that affects both the creation of a multi-release JAR file and using it in your application.

What's new in Java?

Manoj Palat (IBM)

Having read the specification at the evolution phases as a JSR member and then having implemented some of these language features in the Eclipse Java Compiler (ECJ) of Java Development Tools (JDT), planning to bring in the perspective of "why" a particular feature exists in the first place. Of course, I will be covering the "what" in detail, and then planning to go into a few major characteristics of each feature to help the attendee go beyond the "dry" lecture of different language features.

JDT As A Service

Roland Grunberg (Red Hat, Inc.)

With technologies like Quarkus and GraalVM emphasizing the importance of Java ecosystem in the cloud, good language support becomes important across various IDEs.

The JDT project has been around for a long time so it would be nice if all could benefit from the work that has gone into it, rather than having to reinvent the wheel.

Extending JDT with Language Servers

Martin Lippert (Pivotal Software, Inc now under VMWare-April 2020)

This talk shows how to use language servers to enhance the existing Java tooling in Eclipse. We explain how language servers can be integrated into JDT so that they work together in a seamless way using the LSP4E project and what custom code needs to be written for that integration.

Making Eclipse JDT Future–ready - Java 11 and Beyond

Manoj Palat (IBM)

Eclipse Java Development Tool (JDT) is witnessing rapid changes now, thanks to the faster Java release cycles – Since Java 9, a new Java version arrives every six months! Java 10 and Java 11 (due Sep 2018) releases have many explicit and implicit Java features in them. For e.g., “var” support was an explicit feature. There are features like Nest, Constant Dynamic, etc. that is in Java 11 along with enhancements to var support. Some of these features contain more than what meets the eye; they serve as building blocks of new features on the horizon. This talk will discuss how Eclipse JDT has incorporated new language features from a user perspective and the challenges involved. This talk will give a sneak peek into some of the major upcoming language features in the works as well.
