Target Environments

In order to remain current, each Eclipse release targets reasonably current versions of the underlying operating environments. The ATL project depends upon on the Platform and other projects, which are mostly "pure" Java. The 3.5 release of the Eclipse Platform Project is written and compiled against version 1.4 of the Java Platform APIs, and targeted to run on version 1.4 of the Java Runtime Environment, Standard Edition. ATL will target the same Java version as the platform.


The Eclipse Platform is designed as the basis for internationalized products. The user interface elements provided by the Eclipse SDK components, including dialogs and error messages, are externalized. The English strings are provided as the default resource bundles. As a result, the ATL project will provide English strings in its default bundles and be localized to a subset of those locales offered by the Platform. This plan will be updated to indicate which locales will be provided and the time frame for availability.
