Scout 4.0 was released with the Luna Simultaneous Release.

Scout has changed its version numbering policy
With the Eclipse Luna release train Scout is changing its version numbering policy. With each release train Scout is participating in, Scout will increase its major version number. As a result, Scout will ship version 4.0 as part of the Eclipse Luna release train.

Target Environment


All of Eclipse Scout is "pure" Java code and has no direct dependence on the underlying operating system. The chief dependence is therefore on the Java Runtime (JRE) itself. The Scout 4.0 release of is still compatible with Java SE 6. Most users of Scout, however, will probably want to run their project with the most curent version of Java 7. Support for Java 8 is still experimental at the moment.

The eclipse scout package only runs with Java >=1.7.

Java Version Support for Scout Runtime/SDK
6 supported (on Windows/Linux)
7 recommended
8 experimental

Eclipse Platform

For the Luna release of Scout we recommend developing Scout with Eclipse Luna (4.4) and using Eclipse 3.8 as a target platform. Scout is still using the compatibility layer for the eclipse 3.x stream. (See Scout/Targets for more detail).

The following Eclipse platforms are supported:

Eclipse Version Scout Runtime Scout SDK
Helios (3.6.2) supported -
Indigo (3.7.2) supported supported
Juno (3.8.2) recommended supported
Juno (4.2.2) - supported
Kepler (4.3.2) - supported
Luna (4.4) supported recommended

RAP Version

Eclipse Scout and RAP are participating in the Simultaneous Release and therefore needs to support RAP 2.3.0. (see Luna Projects).

RAP Version Scout Runtime
2.3.0 supported

Browser Versions

The web UI for Scout is based on RAP (Version 2.3) and therefore only supports the browser version supported by RAP:

  • Microsoft Internet Explorer 9+
  • Google Chrome 7+
  • Firefox 9+
  • Safari 5+
  • Android 3 (Limited)

Tested Platforms

We focus our testing on a handful of popular combinations (OS, HW Arch, Java VM, Eclipse platform); these are our reference platforms. Scout undoubtedly runs fine in many operating environments beyond the reference platforms we test. However, since we do not systematically test them we cannot vouch for them. Problems encountered when running Scout on a non-reference platform that cannot be recreated on any reference platform will be given lower priority than problems with running Scout on a reference platform.

Scout 4.0 will be tested and validated on the following reference platforms:

Operating System OS Version Hardware Java VM (vendor, version, arch) Eclipse Platform (version, arch)
Windows 7 x86 32-bit Oracle JDK 7, 32-bit 3.7.2, 32-bit
x86 64-bit 3.8.2, 32-bit
Oracle JDK 7, 32-bit 4.4, 32-bit, EPP
Oracle JDK 7, 64-bit 4.4, 64-bit, EPP
Oracle JDK 8, 64-bit 4.4, 64-bit, EPP
8 x86 64-bit Oracle JDK 7, 64-bit 4.4, 64-bit, EPP
Oracle JDK 8, 32-bit 4.4, 32-bit, EPP
Ubuntu Linux 13.10 x86 64-bit OpenJDK 7, 64-bit 4.4, 64-bit, EPP
x86 32-bit OpenJDK 7, 32-bit 4.4, 32-bit, EPP
Apple Mac OS 10.8 x86 64-bit Oracle JDK 7, 64-bit 4.4, 64-bit, EPP

Compatibility with Previous Releases

Scout RT 4.0 will NOT be compatible with Scout 4.0. How to migrate from 3.9 to 4.0 is described in the migration guidelines.

We try to make migration to new releases as easy as possible, however to keep our code clean and simple we need to change the API in new releases. There are no more API changes after milestone M6. API Compatibility rules are described in the coding guidelines in more detail.

Scout SDK 4.0 will NOT be compatible with Scout SDK 3.9. Currently, the Scout SDK API is not yet used frequently.


Some functionality will be dropped completely with Scout 4.0. We suppose this won't be an issue for most Scout projects.

  • Eclipse Versions: The following eclipse versions that where previously supported or partially supported, are not supported anymore
    • Scout RT: 3.4,3.5,4.2,4.3
    • Scout SDK: 3.7
  • Rap Versions: RAP 1.5 is not supported anymore, the current RAP version is 2.3
  • Legacy Texts: The fragment org.eclipse.scout.rt.shared.legacy.texts.fragment will be removed

Ramp down Policy

We use daily builds. No API changes after M6, no new features after M7. In the RC phase only bugs marked P2 or higher or severity major or higher will be fixed.

Build Process

Scout is built on Hudson @ Eclipse.

Scout is using maven and tycho for building.

  • Gerrit Jobs run build against lowest target platform with runtime unit tests
  • Nightly Jobs run against all platforms with all unit tests
  • Release Jobs can be parameterized for a specific tag and deploy to a specific updatesite
  • Some tests currently still run only at BSI's infrastructure: Scout GUI tests using java.awt.Robot, because they need a fully-fledged desktop environment.
