How to download Eclipse 2021-06
To download Eclipse 2021-06 on your computer, you need to follow these steps:
Choose the right package for your needs
Eclipse offers different packages for different types of development. Each package contains a pre-configured set of plugins and features that are suitable for a specific domain or technology. For example, if you want to develop Java applications, you can choose the Eclipse IDE for Java Developers package. If you want to develop web applications, you can choose the Eclipse IDE for Enterprise Java and Web Developers package. If you want to develop C/C++ applications, you can choose the Eclipse IDE for C/C++ Developers package. And so on.
You can find a list of all available packages on the . You can also compare the contents of each package by clicking on the Compare Packages link on the same page. Alternatively, you can download the Eclipse Installer, which allows you to choose from a variety of packages or create your own custom package. The Eclipse Installer also provides more options and flexibility for installing and updating Eclipse.
Download the Eclipse Installer or the package archive
Once you have decided which package you want to use, you can download it from the Eclipse downloads page. You can either download the Eclipse Installer, which is a small executable file that will download and install the package for you, or you can download the package archive, which is a large zip file that contains the entire package. The advantage of using the Eclipse Installer is that it will always download the latest version of the package and it will also check for updates and patches. The advantage of using the package archive is that you can download it once and use it offline or on multiple computers.
To download the Eclipse Installer, click on the Download button next to the Eclipse Installer option on the Eclipse downloads page. You will be redirected to a mirror site that will provide you with the fastest download speed. Choose the appropriate version of the Eclipse Installer for your operating system (Windows, macOS, or Linux) and save it to your computer. The file name should be something like eclipse-inst-win64.exe, eclipse-inst-mac64.dmg, or eclipse-inst-linux64.tar.gz.
To download the package archive, click on the Download button next to the package name on the Eclipse downloads page. You will be redirected to a mirror site that will provide you with the fastest download speed. Choose the appropriate version of the package archive for your operating system (Windows, macOS, or Linux) and save it to your computer. The file name should be something like eclipse-java-2021-06-R-win32-x86_64.zip, eclipse-java-2021-06-R-macosx-cocoa-x86_64.dmg, or eclipse-java-2021-06-R-linux-gtk-x86_64.tar.gz.
Verify the download integrity (optional)
If you want to make sure that your download is complete and not corrupted, you can verify its integrity by comparing its checksum or signature with the ones provided by Eclipse. A checksum is a string of numbers and letters that is calculated from the contents of a file. A signature is a file that is created by encrypting a checksum with a private key. You can use a tool such as MD5, SHA1, SHA256, or GPG to generate or verify checksums or signatures.
To verify the download integrity, follow these steps:
Go to the and find the checksum or signature for your download.
Download and install a tool that can generate or verify checksums or signatures, such as MD5, SHA1, SHA256, or GPG.
Run the tool and compare the checksum or signature of your download with the one provided by Eclipse.
If they match, your download is valid and intact. If they do not match, your download is corrupted or tampered with and you should download it again.
Verifying the download integrity is an optional step that can increase your security and confidence, but it is not mandatory for installing Eclipse.
How to install Eclipse 2021-06
To install Eclipse 2021-06 on your computer, you need to follow these steps:
Run the Eclipse Installer or extract the package archive
If you have downloaded the Eclipse Installer, run it by double-clicking on it. You may need to grant permission for it to run if prompted by your operating system. The Eclipse Installer will launch and guide you through the installation process. You can choose from a list of packages or create your own custom package. You can also change some settings such as proxy configuration, network timeout, etc.
If you have downloaded the package archive, extract it by right-clicking on it and choosing Extract All (Windows), Open (macOS), or Extract Here (Linux). You may need to install a tool such as WinZip, WinRAR, 7-Zip, etc., if your operating system does not support zip files natively. The extraction process will create a folder named eclipse in your chosen location. This folder contains all the files and folders of your Eclipse package.
Select a folder for your Eclipse installation
If you have used the Eclipse Installer, you can select a folder for your Eclipse installation during the installation process. By default, the Eclipse Installer will create a folder named eclipse in your user home directory (such as C:\Users\username\eclipse on Windows). You can change this location by clicking on the Browse button and choosing another folder. You can also create a new folder by clicking on the New Folder button.
If you have extracted the package archive, you can select any folder for your Eclipse installation. You can move the eclipse folder that you have extracted to any location on your computer. You can also rename the folder if you want. However, you should avoid using spaces or special characters in the folder name, as they may cause problems with some plugins or features.
Launch Eclipse and create a workspace
To launch Eclipse, open the eclipse folder that you have installed and double-click on the eclipse executable file. The file name should be something like eclipse.exe (Windows), Eclipse.app (macOS), or eclipse (Linux). You may need to grant permission for it to run if prompted by your operating system. The Eclipse splash screen will appear and show the progress of the startup process.
The first time you launch Eclipse, you will be asked to select a workspace. A workspace is a folder that contains all your projects, settings, preferences, and metadata. By default, Eclipse will create a workspace folder named workspace in your user home directory (such as C:\Users\username\workspace on Windows). You can change this location by clicking on the Browse button and choosing another folder. You can also create a new folder by clicking on the New Folder button.
You can also check the option to use this as the default and do not ask again if you want to use the same workspace every time you launch Eclipse. Alternatively, you can check the option to switch workspaces on startup if you want to choose a different workspace every time you launch Eclipse. You can also switch workspaces later by selecting File > Switch Workspace from the menu bar.
Once you have selected a workspace, click on the Launch button to start Eclipse. The Eclipse workbench will appear and show the default perspective, which is a set of views and editors that are arranged for a specific type of development. For example, the Java perspective has views and editors for editing, compiling, debugging, and testing Java code. You can change the perspective by selecting Window > Perspective > Open Perspective from the menu bar.
