Target Environments

In order to remain current, each Eclipse release targets reasonably current versions of the underlying operating environments. The Xtext project depends upon on the 3.5 (Galileo) release of the Eclipse Platform and other projects, and targets to run on version 1.5 of the Java Runtime Environment, Standard Edition.

Compatibility with Previous Releases

Version 2.3 will be binary but not sourcecompatible with Xtext version 2.0, 2.1 and 2.2. This means languages developed and compiled against 2.0, 2.1 and 2.2 will work with 2.3 without recompilation.

Themes and Priorities

A list of project requirements and agreed upon implementation time frames is found in this document. For the milestones listed in this document, a set of overall themes is used to indicate what major set of functionalities is to be concentrated on for each. These themes are presented below, while the requirements document and associated Bugzilla entries are left to those wanting more detailed information on each.


The usability of Xtend and its supporting tooling is of high priority, since it's meant to be used in day to day programming.


The language semantics, the compiler and the tools shall be stable and reliable.

Performance and Scalability

Performance and scalability needs to be further enforced.

JDT integration

Seamless integration with the Java Development Tools (JDT) is of high priority.
