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.
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 14 and 15 features would include Switch Expressions, Records, Text Blocks, Pattern InstanceOf, and Sealed Types.
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.
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.
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.
Eclipse IDE provides a lot of powerful features and capabilities. With so much functionality at disposal, many users don't use the full potential of the IDE. To be productive, mastering your IDE is as important as mastering your source code.
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.
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.
