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.

  • Which JDK 8 version did you download and when? The timestamp on these directories are quite old. From the attached screenshot are these 32 bit or 64 bit versions? Would it be possible that you downloaded a different bit version from the one's in the image? In that case your installation would be in another directory. – Mars Mar 04 '19 at 15:56

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

  • I was only checking on `Program Files (x86)\Java` folder and it was installing on `Program Files\Java` – Erik Mar 05 '19 at 14:10

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.
