November 7, 2001, Release of Eclipse 1.0. Six months later, June 27, 2002, Eclipse entered the 2.0 era. Eclipse of the 2.0 era experienced 2.0 and 2.1 two large versions. Of these, 2.0 were followed by the introduction of 2.0.1 and 2.0.2, followed by the release of the 2.1 version on March 27, 2003, with the introduction of 2.1.1,2.1.2 and 2.1.33 subsequent revisions.
June 25, 2004 is a memorable day for Eclipse, with the OSGi runtime architecture being introduced into Eclipse 3.0. The Eclipse Foundation was established this year, which also marks the beginning of Eclipse's coming into a new era. After 3.0 there are two small revisions of 3.0.1 and 3.0.2.

June 27, 2005 Eclipse 3.1 was released, specifically to mention 3.1, because from this version until the release of the 3.5 version, the formation of a Jupiter satellite name-related series. In 1610, the famous scientist Galileo Galilei, through the observation of the Europa 1-Ganymede 4, presented evidence against Geocentric, and Ganymede 1-Ganymede 4 is also known as Galileo's four moons (and many other satellites later discovered by Jupiter). The four moons were also given the names of four mythical characters:
Europa 1:io, Theo
Ganymede 2:europa, Europa
Ganymede 3:ganymede, Genimide. (It is worth mentioning that earlier than Galileo 2000 years ago, there is a record that the Warring States period of China's Gander in 346 BC discovered the Europa 3)
Europa 4:callisto, Calisto
One of the most important reasons to take the names of these four people is that these four characters are famous for their beauty.
But Eclipse's naming from 3.1 to 3.4 (codename) is not in the order of Europa 1-4, but on the order of the four satellites from Jupiter from near to far, so Eclipse 3.1 is named after the 1th nearest 1--io in Jupiter's known satellite, eclipse 3.2 The use of the 4--callisto from Jupiter (all the Europa) 4th near, Eclipse 3.3 using the Europa 2--europa (6th near), the remaining 3--ganaymede of the most distant wood is sent to Eclipse 3.4.
