Is there at least anything other than Vogella's tutorials and his book, which is completely based on those tuts? Examples from his repo are often either incomplete/unfinished/won't run and those examples even don't match the book actually.. I'd like to find at least some javadoc for this, because any step to a side and I'm completely lost on how to accomplish different tasks and what functionality is available.
Lars Vogel's Tutorials are the most complete and up-to-date documentation on Eclipse 4 development. Second to this is asking questions in Eclipse 4 Community Forum. Last option is to google for specific technical problems, which will in most cases lead you to blog posts from the same people that are active on the forums. (Mainly single supporters like Lars, some Eclipse devs and the guys from www.eclipsesource.com)
The only answer I have is - move to the NetBeans Platform. There are similar problems there, but at least people do answer in the mailing list and there are books which are quite more recent and are actually providing working source code! Enve the NetBeans website provides free tutorial on a lot of stuff for free!
For example, the following command will install the components EGit, Mylyn and EMF into an Eclipse instance.You need to start this command in the command line and it assumes that you are in a directory which contains your Eclipse installation in a folder called eclipse.
Your Eclipse installation contains a file calledeclipse.iniwhich allows you to configure the memory parameters for theJavavirtualmachine which runs the Eclipse IDE. Forexample,the-Xmxparameter can be used to define how large the Java heap size canget.-Xmsdefines the initial heap size of the Java virtual machine.
The following listing shows an exampleeclipse.inifile. The parameters after -vmargs configure the Java virtualmachine.On a modern machine (with at least 8 Gigabyteavailable memory) assigning 2024 MB or more tothe Javavirtualmachine is a good practice to run Eclipse faster.

I had this exact issue attempting to run JasperReport Studio 6.4.3, and in my case, I have had (and still have) many eclipse versions on my machine, as well as multiple versions of Jaspersoft Studio (5.5, 6.1, and possibly 6.3). The only thing that worked for me was going to C:\Users\
Thanks for your answer. Actually, I also tried to remove .eclipse and all the directories you mentionned, but it doesn't really change the behavior. By the way, I've been able to start it maybe 3 times over 30 attempts.
I've read some similar thread related to eclipse only, some people said that it can be related to the Antivirus, but unfortunatly I'm on a corporate PC on which it's not possible to modify antivirus policy.
- .eclipse is not the only folder that will impede Jasper's ability to start. I noticed other folders on other workstations, such as one related to ireport (I think it was .ireport or something similar) that can do the same. There's no easy way to determine which folders Jasper is searching for, scanning, and crashing itself with the existence of. Very frustrating.- Installation of this version is clearly buggy and needs fixing. Perhaps improved in the later versions that have appeared since then ( I think 6.5.1 is out now).
An eclipse is an astronomical event that occurs when an astronomical object or spacecraft is temporarily obscured, by passing into the shadow of another body or by having another body pass between it and the viewer. This alignment of three celestial objects is known as a syzygy. Apart from syzygy, the term eclipse is also used when a spacecraft reaches a position where it can observe two celestial bodies so aligned. An eclipse is the result of either an occultation (completely hidden) or a transit (partially hidden).
For the special cases of solar and lunar eclipses, these only happen during an "eclipse season", the two times of each year when the plane of the Earth's orbit around the Sun crosses with the plane of the Moon's orbit around the Earth and the line defined by the intersecting planes points near the Sun. The type of solar eclipse that happens during each season (whether total, annular, hybrid, or partial) depends on apparent sizes of the Sun and Moon. If the orbit of the Earth around the Sun and the Moon's orbit around the Earth were both in the same plane with each other, then eclipses would happen each and every month. There would be a lunar eclipse at every full moon, and a solar eclipse at every new moon. And if both orbits were perfectly circular, then each solar eclipse would be the same type every month. It is because of the non-planar and non-circular differences that eclipses are not a common event. Lunar eclipses can be viewed from the entire nightside half of the Earth. But solar eclipses, particularly total eclipses occurring at any one particular point on the Earth's surface, are very rare events that can be many decades apart.
For any two objects in space, a line can be extended from the first through the second. The latter object will block some amount of light being emitted by the former, creating a region of shadow around the axis of the line. Typically these objects are moving with respect to each other and their surroundings, so the resulting shadow will sweep through a region of space, only passing through any particular location in the region for a fixed interval of time. As viewed from such a location, this shadowing event is known as an eclipse.
A total eclipse occurs when the observer is within the umbra, an annular eclipse when the observer is within the antumbra, and a partial eclipse when the observer is within the penumbra. During a lunar eclipse only the umbra and penumbra are applicable, because the antumbra of the Sun-Earth system lies far beyond the Moon. Analogously, Earth's apparent diameter from the viewpoint of the Moon is nearly four times that of the Sun and thus cannot produce an annular eclipse. The same terms may be used analogously in describing other eclipses, e.g., the antumbra of Deimos crossing Mars, or Phobos entering Mars's penumbra.
An eclipse cycle takes place when eclipses in a series are separated by a certain interval of time. This happens when the orbital motions of the bodies form repeating harmonic patterns. A particular instance is the saros, which results in a repetition of a solar or lunar eclipse every 6,585.3 days, or a little over 18 years. Because this is not a whole number of days, successive eclipses will be visible from different parts of the world. In one saros period there are 239.0 anomalistic periods, 241.0 sidereal periods, 242.0 nodical periods, and 223.0 synodic periods. Although the orbit of the Moon does not give exact integers, the numbers of orbit cycles are close enough to integers to give strong similarity for eclipses spaced at 18.03 yr intervals.
An eclipse involving the Sun, Earth, and Moon can occur only when they are nearly in a straight line, allowing one to be hidden behind another, viewed from the third. Because the orbital plane of the Moon is tilted with respect to the orbital plane of the Earth (the ecliptic), eclipses can occur only when the Moon is close to the intersection of these two planes (the nodes). The Sun, Earth and nodes are aligned twice a year (during an eclipse season), and eclipses can occur during a period of about two months around these times. There can be from four to seven eclipses in a calendar year, which repeat according to various eclipse cycles, such as a saros.
As observed from the Earth, a solar eclipse occurs when the Moon passes in front of the Sun. The type of solar eclipse event depends on the distance of the Moon from the Earth during the event. A total solar eclipse occurs when the Earth intersects the umbra portion of the Moon's shadow. When the umbra does not reach the surface of the Earth, the Sun is only partially occulted, resulting in an annular eclipse. Partial solar eclipses occur when the viewer is inside the penumbra.
The eclipse magnitude is the fraction of the Sun's diameter that is covered by the Moon. For a total eclipse, this value is always greater than or equal to one. In both annular and total eclipses, the eclipse magnitude is the ratio of the angular sizes of the Moon to the Sun. 2b1af7f3a8
