Hello,

I'm working on a certain project in Eclipse Kepler 4.3 that requires to be launched in Java 8. I tried downloading Java 8 feature patch, but the link to the patch (http://download.eclipse.org/eclipse/updates/4.3-P-builds/) doesn't work. Can someone please fix the link or send me a new link to the feature patch? Thanks.

Hi,
As the Java 8 to Java 18 feature are already integrated to Eclipse IDE versions the feature patches are not available any more.
Try using a newer Eclipse IDE.

No, here are all the releases and you can see that Kepler is really, really old.

That means the version I'm using is probably not Kepler. Sorry for confusion. I don't know how is the version I'm using called, the icon on the desktops says "Eclipse IDE for Java Developers - 2022-03. I downloaded it a few days ago as the newest version available on Eclipse website. Nevertheless, it doesn't solve my main problem. When I try to launch the program I'm working on (a Minecraft modd, to be precise), it crashes. According to someone on Minecraft forum, who saw my post I posted there (along with the stacktrace of the error), it is because the mods for the particular version of Minecraft I'm creating the mod for require to be launched in Java 8. Which the Eclipse version I'm using is apparently not capable of doing (or at least I don't know how to do it). Any suggestions what to do? Thanks.

(Sorry for possibly bad English, it is not my native language)

The latest version of Eclipse can launch Java 8 applications. If you want to use Java 8 you need to use Window -> Preferences -> Java -> Installed JREs > Add... and tell it where your JDK or JRE 8 is located. Then you can use it when you launch an application.
