Thirty Nine Projects

The Eclipse Helios Release Train Arrives On Time

33 million lines of new code for Eclipse fans!

On June 23rd, 2010 Eclipse shipped the 33 million lines of code
and thirty nine projects that make up the Helios simultaneous release. To put the size of
this release into context – in 2006 the Eclipse Callisto release
train consisted of 7 million lines of code, and coordinated 10
teams with 260 committers.

The Helios release is the largest release train produced by the
Eclipse community, and is available as twelve themed Eclipse
packages that target developers working within different areas. For
example, there is a package for PHP developers, Java EE developers,
and C/C++ developers. Helios is also available via the Helios
software repository at Please note that you must first
download the Eclipse V3.6 SDK before you can download Helios from
the repository.

Helios features several projects which are particularly
noteworthy, including the Eclipse Marketplace Client, which was
launched as part of the Eclipse Helios release. The client was
proposed as a new Eclipse project in February 2010, as
an Eclipse-based rich client for installing solutions listed in the
Eclipse Marketplace. “The Eclipse community has hundreds, if not
thousands, of third-party plugins that users can add to their
Eclipse installation. Unfortunately, there is no easy way to
discover and install these solutions from within Eclipse,” read the
proposal. The Marketplace Client is available to users who download
Helios via a package, and can be accessed via Help > Marketplace

In addition to the Eclipse Marketplace Client, another notable
part of this year’s release train, is the Linux Tools project,
which aims to provide a C and C++ IDE for Linux developers. This
project is particularly timely: the
2010 Eclipse Community survey
found that almost a third of
those surveyed used the Linux operating system for software

Version 0.6 of Linux Tools, is included in the Helios

More noteworthy projects include the JavaScript Development
Tools project, which reworks the Java Development Toolkit to work
with JavaScript. It comes preconfigured with the Rhino debug
system. There is also the Sequoyah attempt to provide a unified
mobile development IDE, and the Xtext language development
framework, which can be used to describe the syntax and semantics
of a language.

This year also saw a new ‘Friends of Helios‘ program contributing to the
Helios build-up, as Eclipse set out to recruit 360 new Friends of
Eclipse. A £35 donation not only earned you the Friends title, but
also early access to the Helios release, direct from the download
server at the Eclipse Foundation.

Looking ahead, the Eclipse community recently decided that the
name of the next simultaneous release should be ‘Indigo.’ Indigo
will be released in June 2011 – until then, Eclipse Helios can be
downloaded from
