Xtext 2.29.0 Release Notes  Nov 21, 2022


Xtext 2.29.0 is a maintenance release.

Call to Action: Secure the future maintenance of Xtext

As you might have recognized, the number of people contributing to Xtext on a regular basis has declined over the past years and so has the number of contributions. At the same time the amount of work for basic maintenance has stayed the same or even increased with the new release cadence of Java and the Eclipse simultaneous release.

If you care, please join the discussion in https://github.com/eclipse/xtext/issues/1721.

Xtext and Java 17

Xtext now supports Java 17 as source and target, too. This requires newer Eclipse platform and JDT versions that do no longer run on Java 8. That’s why the Xtext framework and Xtend compiler require Java 11 as minimal Java version from 2.29 onwards. While we were at it we also bumped the minimal tested Eclipse version to 2022-03 (2.28 was still compatible to and tested against Eclipse Oxygen). Please Note: We did no special treatment for newer Java constructs in Xtend, so what works, works, what does not, does not - the latter being most likely intentional. Please engage by filing bugs or pull requests (see also issue#1982.

Upgrades

  • LSP4J was updated to 0.19.0
  • GSON to 2.9.1
  • Classgraph is now at 4.8.149
  • ASM is now on 9.4
  • MWE(2) is now at 1.8.0 / 2.14.0
  • JUnit5 at 5.9.1

Changes / Enhancements

Standalone Builder

The Incremental Standlone Builder is now capable of performing incremental builds. Depending on the changes that happened since the previous compile run, only a subset of the model files need to be processed. Both model and Java file changes as well as class-path changes are taken into account. The feature is opt-in since it might break backwards compatibility for DSLs that use non-default code generation patterns. Incremental builds can also be enabled for the Xtext maven plugin xtext-extras#805.
