Xtend is a statically-typed programming language which compiles into Java source code. It is 100% compatible with any existing Java code, but offers a much more concise syntax and many important features missing in Java.
With local type inference users don't have to pollute the code with redundant type information. Yet the code is statically-typed, so you get useful error messages.
Advanced Eclipse Plug-In
The language was designed together with the IDE, to ensure a great and holistic user experience. It relies on the static type information and integrates tightly with the JDT (Java Development Tools).
Xtend offers a very concise syntax for lambda expressions. Lambda expressions in Xtend automatically convert to any type with just one method, allowing to use Lambdas instead of noisy anonymous classes in existing Java APIs.
Rich string concatenation through a template syntax is built into Xtend, to ensure creating text, being it for websites or for code generation, doesn't force the user to switch to a half-baked template language.
Switch of types
The switch expression in Xtend is very powerful and replaces all the instanceof/casting cascades you'll find in Java code a lot.
New in this release

The Xtend project leadership verifies that:
- the about files and use licenses are in place as per the Guidelines to Legal Documentation.
- all contributions (code, documentation, images, etc) have been committed by individuals who are either Members of the Foundation, or have signed the appropriate Committer Agreement. In either case, these are individuals who have signed, and are abiding by, the Eclipse IP Policy.
- all significant contributions have been reviewed by the Foundation's legal staff.
- all non-Committer code contributions, including third-party libraries, have been documented in the release and reviewed by the Foundation's legal staff.
- all Contribution Questionnaires have been completed.
- the "provider" field of each plug-in is set to "Eclipse Xtend“.
- the "copyright" field of each feature is set to the copyright owner (the Eclipse Foundation is rarely the copyright owner).
- any third-party logos or trademarks included in the distribution (icons, help file logos, etc) have been licensed under the EPL.
- any fonts or similar third-party images included in the distribution (e.g. in PDF or EPS files) have been licensed under the EPL.
