JDK 1.8 not being installed, only JRE on Windows

Question

I'm trying to make a Spring application with Kotlin and stumbled in a problem with the problem Unsupported major.minor version 52.0 on class KotlinJpaSubplugin . I went to Oracle's site to download JDK 1.8 ( https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html ). The problem is, the installer only installs the JRE and not JDK. I'm not very good with java versions, so what I'm missing?

Here is an image of the java folder in my PC. Only JRE 1.8 is installed, the only JDK is the old 1.7.

Answer 1

The link you've provided is correct.

You've most likely downloaded one of these items:

• Windows x86 201.64 MB jdk-8u202-windows-i586.exe
• Windows x64 211.58 MB jdk-8u202-windows-x64.exe

Something you can do:

• Make sure to check both ' Program Files\\Java ' and ' Program Files (x86)\\Java ' folders. By default JDK should be installed there.

• Use OS level search, to look for ' jdk1.8 ' or ' 1.8.0 ' folders

• In case you're still missing it, you can try to manually extract the JDK folder from installer - https://stackoverflow.com/a/25384578/3523579

Answer 2

For whatever reason, Windows x86 202.73 MB jdk-8u221-windows-i586.exe only installs a jre. get Windows x64 215.35 MB jdk-8u221-windows-x64.exe which will install a JDK folder.
