How to Download Eclipse IDE 2021-12




Downloading and installing Eclipse IDE 2021-12 is relatively easy, but it does involve a few steps and software from at least two different sources. First, you need to have a Java Runtime Environment (JRE) or Java Development Kit (JDK) installed on your computer. The latest release of Eclipse requires a 64-bit JVM and does not support a 32-bit JVM. It also requires Java 17 or newer. If you are using Eclipse for Java development or are on macOS, you should install a JDK instead of a JRE.


Second, you need to download the appropriate package of Eclipse IDE 2021-12 from the official Eclipse website. There are different packages available depending on your needs and preferences. For example, if you are mainly developing Java applications, you can download the Eclipse IDE for Java Developers package. If you are developing web applications, you can download the Eclipse IDE for Enterprise Java and Web Developers package. You can also download the Eclipse Installer, which allows you to choose from various packages and customize your installation.


Third, you need to extract the downloaded package to a folder of your choice. You can use any file compression tool such as WinZip, 7-Zip, or the built-in Windows or macOS tools. You should avoid extracting the package to a folder that requires administrator privileges, such as Program Files or Applications. You should also avoid using spaces or special characters in the folder name.


Finally, you need to run the eclipse.exe file (on Windows) or the Eclipse.app file (on macOS) to launch the Eclipse IDE. You will be asked to select a workspace folder, which is where your projects and settings will be stored. You can use the default workspace or create a new one. You can also switch workspaces later from the File menu.


The following sections will provide more detailed instructions for each platform.

What's New in Eclipse IDE 2021-12




Eclipse IDE 2021-12 is the latest release of the open source IDE that brings many new features and improvements to enhance your development experience. Here are some of the highlights of this release:


Java Development Tools (JDT)




The JDT component of Eclipse IDE provides tools for developing Java applications, such as editors, compilers, debuggers, refactoring tools, code analysis tools, etc. In this release, the JDT component has been updated to support Java 17, which is the latest long-term support (LTS) version of Java. Some of the new features of Java 17 that are supported by JDT include:


  • Sealed classes and interfaces: These are classes and interfaces that restrict which other classes or interfaces may extend or implement them. They allow you to define a fixed set of subclasses or subinterfaces for a given superclass or superinterface.



  • Pattern matching for switch expressions: This feature allows you to use patterns in switch expressions to match values based on their type, structure, or properties. It also allows you to bind variables to parts of the matched value.



  • Text blocks: These are multi-line string literals that avoid the need for most escape sequences and automatically format the string in a predictable way.



Records: These are classes that act as transparent carriers for immutable data. They provide a compact syntax for declar
