What is the difference between versions of Eclipse (Europa, Helios, Galileo)? Which is the best for desktop application?
The Eclipse (software) page on Wikipedia summarizes it pretty well:
Releases
Since 2006, the Eclipse Foundation has coordinated an annual Simultaneous Release. Each release includes the Eclipse Platform as well as a number of other Eclipse projects. Until the Galileo release, releases were named after the moons of the solar system.
So far, each Simultaneous Release has occurred at the end of June.
Release Main Release Platform version Projects Photon 27 June 2018 4.8 Oxygen 28 June 2017 4.7 Neon 22 June 2016 4.6 Mars 24 June 2015 4.5 Mars Projects Luna 25 June 2014 4.4 Luna Projects Kepler 26 June 2013 4.3 Kepler Projects Juno 27 June 2012 4.2 Juno Projects Indigo 22 June 2011 3.7 Indigo projects Helios 23 June 2010 3.6 Helios projects Galileo 24 June 2009 3.5 Galileo projects Ganymede 25 June 2008 3.4 Ganymede projects Europa 29 June 2007 3.3 Europa projects Callisto 30 June 2006 3.2 Callisto projects Eclipse 3.1 28 June 2005 3.1 Eclipse 3.0 28 June 2004 3.0
To summarize, Helios, Galileo, Ganymede, etc are just code names for versions of the Eclipse platform (personally, I'd prefer Eclipse to use traditional version numbers instead of code names, it would make things clearer and easier). My suggestion would be to use the latest version, i.e. Eclipse Oxygen (4.7) (in the original version of this answer, it said "Helios (3.6.1)").
On top of the "platform", Eclipse then distributes various Packages (i.e. the "platform" with a default set of plugins to achieve specialized tasks), such as Eclipse IDE for Java Developers, Eclipse IDE for Java EE Developers, Eclipse IDE for C/C++ Developers, etc (see this link for a comparison of their content).
To develop Java Desktop applications, the Helios release of Eclipse IDE for Java Developers should suffice (you can always install "additional plugins" if required).
Those are just version designations (just like windows xp, vista or windows 7) which they are using to name their major releases, instead of using version numbers. so you'll want to use the newest eclipse version available, which is helios (or 3.6 which is the corresponding version number).
To see a list of the Eclipse release name and it's corresponding version number go to this website. http://en.wikipedia.org/wiki/Eclipse_%28software%29#Release
- Release Date Platform version
- Juno ?? June 2012 4.2?
- Indigo 22 June 2011 3.7
- Helios 23 June 2010 3.6
- Galileo 24 June 2009 3.5
- Ganymede 25 June 2008 3.4
- Europa 29 June 2007 3.3
- Callisto 30 June 2006 3.2
- Eclipse 3.1 28 June 2005 3.1
- Eclipse 3.0 21 June 2004 3.0
I too dislike the way that the Eclipse foundation DOES NOT use the version number for their downloads or on the Help -> About Eclipse dialog. They do display the version on the download webpage, but the actual file name is something like:
- eclipse-java-indigo-SR1-linux-gtk.tar.gz
- eclipse-java-helios-linux-gtk.tar.gz
But over time, you forget what release name goes with what version number. I would much prefer a file naming convention like:
- eclipse-3.7.1-java-indigo-SR1-linux-gtk.tar.gz
- eclipse-3.6-java-helios-linux-gtk.tar.gz
This way you get BOTH from the file name and it is sortable in a directory listing. Fortunately, they mostly choose names are alphabetically after the previous one (except for 3.4-Ganymede vs the newer 3.5-Galileo).
Each version has some improvements in certain technologies. For users the biggest difference is whether or not to execute certain plugins, because some were made only for a particular version of Eclipse.
In Galileo and Helios Provisioning Platform were introduced, and non-update-site plugins now should be placed in "dropins" subfolder ("eclipse/dropins/plugin_name/features", "eclipse/dropins/plugin_name/plugins") instead of Eclipse's folder ("eclipse/features" and "eclipse/plugins").
Also for programming needs the best Eclipse is the latest Eclipse. It has too many bugs for now, and all the Eclipse team is now doing is fixing the bugs. There are very few interface enhancements since Europa. IMHO.
They are successive, improved versions of the same product. Anyone noticed how the names of the last three and the next release are in alphabetical order (Galileo, Helios, Indigo, Juno)? This is probably how they will go in the future, in the same way that Ubuntu release codenames increase alphabetically (note Indigo is not a moon of Jupiter!).
The Eclipse releases are named after the moons of Jupiter, and each denotes a successive release.
Helios is the current release you can download eclipse as your programming needs http://www.eclipse.org/downloads/
