Eclipse 2021-12: What's New and How to Download It

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)
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.
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)
Enhanced Class Decompiler integrates JD, FernFlower, Quiltflower, CFR, Procyon seamlessly with Eclipse and allows Java developers to debug class files without source code directly. It also integrates with the eclipse class editor, m2e plugin, supports Javadoc, reference search, library source attaching, byte code view and the syntax of JDK8 lambda expression.
It is based on the popular (delisted) "Eclipse Class Decompiler" Plugin, but members of the open-source community enhanced it by removing all code which might compromise your privacy or security (i.e. everything discussed in -engineering-an-eclipse-p... and everything else which seemed suspicious) to bring back the great core plugin functionality to all Eclipse users.
I just read through the interesting blog about how this plugin came into picture and I am excited to use this plugin on my eclipse. But somehow it doesn't decompile. It was installed without a problem but it doesn't show up under Java in Preferences(as in Screenshot).
Did you check if you need a proxy configured in Eclipse? If the problem persist, navigate manually to -plugin.github.io/update/ download the jar files and place them in the features and plugins folde rof your eclipse installation.
I tried to install it on Eclipse 2020-06 Windows 11 but it gives me this error and don't try to tell me to install a new version of eclipse because due to the current project it only works on java 8 and this is the most recent version of eclipse compatible with java 8
Andrew, sorry to hear you're running into this. There are several reasons for a PKIX error, but it's mostly rooted around not being able to establish an HTTPS connection with our servers. This could happen due to a corporiate firewall/proxy not letting the traffic correctly through, or using an older version of Java which doesn't have corresponding certs. My recommenation would be to update the version of Java you use to run Eclipse and/or you can download a copy of our site and install it from a local directory as described here: -installation/
It is an amazing plugin, which makes eclipse look better. But after updating ubuntu to 22.04 javadocs disappeared. Note, they are appearing without devstyle but after installing devstyle javadocs are invisible.
I had to update/install to STS 4.13.0 (based on Eclipse 2021-12 release, 4.22) because of OS updates and getting the error reported: Is the a fix/workadound for this issue, I miss having DevStyle on my IDE.
Eric, STS does seem to ship with a different version of commons.lang3 (3.4) when compared with Eclipse 2021-12, which ships version 3.1.0 - regardless, when we attempted to install DevStyle from the marketplace via simple drang and drop, it installed just fine (plugin in the installation was updated). How did you install STS? You could explicitly add the Eclipse orbit repository ( ) to your available update sites in case it's missing to ensure the commons.lang3 plugin can be found during the install. Do create a post on our forums if you are still having issues where we can dig ino this further.
For those who as unaware as me first time: Under the "Install" button on the left (Yeee, You can install the cilent if you have installed already... ;) ) if you click on the fourth download icon, i the popup you can find the latest download links!
I have installed plugin version 1.0.0.202010091040 and can see that this supports Cucumber 4.2 Is there a planned date for the plugin to support Cucumber 6.x? The file cucumber.eclipse.backends.java_1.0.0.202010091040.jar contains cucumber-java-4.2.0.jar and cucumber-core-4.2.0.jar. Some of the Java classes ahve changed packages after version 4.5.
Plugin installed and recognized the feature files and Gherkin syntax. But it is not detecting step definitons. I have a need to pull some step def from dependency jar as well. In my case, no step definitons are recognized. I also tried with Eclipse 2020-03 release as well. I installed all different ways, from eclipse marketplace, as a zip file. No luck. Any pointers please.

Can hit other websites from eclipse and external browner, but both (https) eclipse-uc.sonarlint.org/content.xml and (http) eclipse-uc.sonarlint.org are not found. Not Found doesn't appear to be a java keystore issue, as some of the help links suggest. Is something else wrong? Is there a way to simply download the plugin rather than install it from marketplace?

Currently, RoboTool targets Eclipse 2021-12, and runs on Java 17. Please note that the graphical editors for RoboChart and RoboSim are incompatible with versions of Eclipse 2022. We suggest installing RoboTool on the package Eclipse Modeling Tools to avoid conflicts between dependencies. Installation is also possible using the Eclipse installer, which also provides the facility to install Java at the same time.
