Re: Eclipse Latest Version

Installing Eclipse is relatively easy, but does involve a few steps and software from at least two different sources. Eclipse is a Java-based application and, as such, requires a Java Runtime Environment or Java Development Kit (JRE or JDK) in order to run.
Regardless of your operating system, you will need to install some Java virtual machine (JVM). You may either install a Java Runtime Environment (JRE), or a Java Development Kit (JDK), depending on what you want to do with Eclipse. If you intend to use Eclipse for Java development, then you should install a JDK. If you aren't planning to use Eclipse for Java development and want to save some disk space, install a JRE.
A Java 17 or newer JRE/JDK is required, LTS release are preferred to run all Eclipse 2023-06 packages based on Eclipse 4.28, with certain packages choosing to provide one by default. The Installer now also includes a JRE--consider using the Installer. Please see 5 Steps to Install Eclipse.
A Java 17 or newer JRE/JDK is required, LTS release are preferred to run all Eclipse 2023-03 packages based on Eclipse 4.27, with certain packages choosing to provide one by default. The Installer now also includes a JRE--consider using the Installer. Please see 5 Steps to Install Eclipse.
A Java 17 or newer JRE/JDK is required, LTS release are preferred to run all Eclipse 2022-12 packages based on Eclipse 4.26, with certain packages choosing to provide one by default. The Installer now also includes a JRE--consider using the Installer. Please see 5 Steps to Install Eclipse.
A Java 17 or newer JRE/JDK is required, LTS release are preferred to run all Eclipse 2022-09 packages based on Eclipse 4.25, with certain packages choosing to provide one by default. The Installer now also includes a JRE--consider using the Installer. Please see 5 Steps to Install Eclipse.
A Java 11 or newer JRE/JDK is required, LTS release are preferred to run all Eclipse 2022-06 packages based on Eclipse 4.24, with certain packages choosing to provide one by default. The Installer now also includes a JRE--consider using the Installer. Please see 5 Steps to Install Eclipse.
A Java 11 or newer JRE/JDK is required, LTS release are preferred to run all Eclipse 2022-03 packages based on Eclipse 4.23, with certain packages choosing to provide one by default. The Installer now also includes a JRE--consider using the Installer. Please see 5 Steps to Install Eclipse.
There are several package choices. Note that you can install the features from any package into any other package. If you are, for example, planning to do mostly Java development and some C/C++ development, you should download the Eclipse IDE for Java Developers and then add the C/C++ development tools via the "Help > Install New Software..." menu option.
The download will be delivered as a compressed (i.e. a ".zip", or ".tar.gz") file. Decompress this file into the directory of your choice (e.g. "c:\eclipse" on Windows) and ensure you have full Read and Execute permissions. You can optionally create a shortcut of the executable file ("eclipse.exe" on Windows, or "eclipse" on Linux).
Note that there is a known problem with the built-in decompression utility on all current versions of Windows. We recommend that you use a more robust decompression utility such as the open source 7zip when decompressing an Eclipse download. Some people report success when initially decompressing Eclipse into a root directory (e.g. c:\) and then moving it to a more appropriate home (e.g. c:\Program Files\Eclipse)
It is strongly recommended to configure Eclipse with the specific JVM that you want. See the instructions at Eclipse.iniThis is a very important step to be sure that Eclipse is using the JVM you intend and can't be influenced by any other software that might alter your system.The JVM used to launch Eclipse has no affect on whether it can compile Java sources for other Java language versions.
Use the Help > Install new software... menu option to add Kepler features to your Eclipse installation (you can, for example, use this option to add C/C++ development support). Additionally, you can tap into a vast collection of extensions provided by the Eclipse community and ecosystem via the Eclipse Marketplace Client (Help > Eclipse Marketplace). Note that not all Eclipse packages contain the Eclipse Marketplace Client.
If you've "installed" Eclipse but are having trouble getting it to run, the most likely cause is that you have not correctly specified the JVM for it to run under. You may need to edit the eclipse.ini file.
Another common mistake on Microsoft Windows is a mismatch between the "bittedness" of Eclipse and the JVM/JDK. This is the most frequent cause of an Error 13. 64-bit Eclipse requires a 64-bit JVM, and 32-bit Eclipse requires 32-bit JVM--you can not mix-and-match between 32-bit and 64-bit, so make sure the version of Eclipse you installed matches the JVM/JDK that you're using to run it (and make sure you're using eclipse.ini to specify the exact JVM used to run Eclipse, described above).
As a simple test, open a Command Prompt window, move to the directory that is pointed to by the -vm argument in your eclipse.ini, and run the intended java.exe with the -d32 switch to test if it supports 32-bit, or -d64 to test for 64-bit support. It's often simplest to download a version of Eclipse that will work with whatever Java you already have installed.
On more recent versions of the Mac, if you don't have a full JDK of an appropriately high version installed, the OS produces this bogus message. Installing any JRE will not eliminate this problem. A full JDK needs to be installed on the Mac.
Eclipse downloads are not password protected. This is a known problem with the built-in decompression utility on all current versions of Windows. We recommend that you either download the installer or use a more robust decompression utility such as the open source 7zip when decompressing an Eclipse download. Some people report success when initially decompressing Eclipse into a root directory (e.g. c:\) and then moving it to a more appropriate home (e.g. c:\Program Files\Eclipse)
Eclipse is an integrated development environment (IDE) used in computer programming.[5] It contains a base workspace and an extensible plug-in system for customizing the environment. It is the second-most-popular IDE for Java development, and, until 2016, was the most popular.[6] Eclipse is written mostly in Java and its primary use is for developing Java applications,[7] but it may also be used to develop applications in other programming languages via plug-ins, including Ada, ABAP, C, C++, C#, Clojure, COBOL, D, Erlang, Fortran, Groovy, Haskell, JavaScript, Julia,[8] Lasso, Lua, NATURAL, Perl, PHP, Prolog, Python, R, Ruby (including Ruby on Rails framework), Rust, Scala, and Scheme. It can also be used to develop documents with LaTeX (via a TeXlipse plug-in) and packages for the software Mathematica. Development environments include the Eclipse Java development tools (JDT) for Java and Scala, Eclipse CDT for C/C++, and Eclipse PDT for PHP, among others.[9]
The initial codebase originated from IBM VisualAge.[10] The Eclipse software development kit (SDK), which includes the Java development tools, is meant for Java developers. Users can extend its abilities by installing plug-ins written for the Eclipse Platform, such as development toolkits for other programming languages, and can write and contribute their own plug-ins. Since Eclipse 3.0 (released in 2004), plug-ins are installed and managed as "bundles" using Equinox, an implementation of OSGi.[11]
The Eclipse SDK is free and open-source software, released under the terms of the Eclipse Public License, although it is incompatible with the GNU General Public License.[12] It was one of the first IDEs to run under GNU Classpath and it runs without problems under IcedTea.
Eclipse was inspired by the Smalltalk-based VisualAge family of integrated development environment (IDE) products.[10] Although fairly successful, a major drawback of the VisualAge products was that developed code was not in a component-based software engineering model. Instead, all code for a project was held in a compressed database using SCID techniques (somewhat like a zip file but in .dat). Individual classes could not be easily accessed, certainly not outside the tool. A team primarily at the IBM Cary, NC lab developed the new product as a Java-based replacement.[13][failed verification]In November 2001, a consortium was formed with a board of stewards to further the development of Eclipse as open-source software. It is estimated that IBM had already invested nearly $40 million by that time.[14] The original members were Borland, IBM, Merant, QNX Software Systems, Rational Software, Red Hat, SuSE, TogetherSoft, and WebGain.[15] The number of stewards increased to over 80 by the end of 2003. In January 2004, the Eclipse Foundation was created.[16]
The Eclipse Public License (EPL) is the fundamental license under which Eclipse projects are released.[19] Some projects require dual licensing, for which the Eclipse Distribution License (EDL) is available, although use of this license must be applied for and is considered on a case-by-case basis.
Eclipse was originally released under the Common Public License, but was later re-licensed under the Eclipse Public License. The Free Software Foundation has said that both licenses are free software licenses, but are incompatible with the GNU General Public License (GPL).[20]
According to Lee Nackman, Chief Technology Officer of IBM's Rational division (originating in 2003) at that time, the name "Eclipse" (dating from at least 2001) was not a wordplay on Sun Microsystems, as the product's primary competition at the time of naming was Microsoft Visual Studio, which Eclipse was to eclipse.[21]
Different versions of Eclipse have been given different science-related names. The versions named after Callisto, Europa, and Ganymede, which are moons of Jupiter, were followed by a version named after Galileo, the discoverer of those moons. These were followed by two sun-themed names, Helios of Greek mythology, and Indigo, one of the seven colors of a rainbow (which is produced by the sun). The version after that, Juno, has a triple meaning: a Roman mythological figure, an asteroid, and a spacecraft to Jupiter.[22] Kepler, Luna, and Mars continued the astronomy theme, and then Neon and Oxygen constituted a theme of chemical elements. Photon represented a return to sun-themed names.
