you are missing the recommended JDK, no matter how many I install the module (Unity 2019.4 LTS)

Question

After switching to 2019.4 LTS I got this error (using Windows 10) You are missing the recommended JDK. Install the recommended version using Unity Hub.

alt text

I installed the JDK using Unity Hub many times now, still the same error. Tho I don't think it's getting installed. As you can see below, the "OpenJDK" checkbox remains blue no matter how many I try to install it.

alt text

When I tried downloading and installing the JDK (JDK 1.8.0_181) myself I get this error instead: You are missing the recommended JDK, versions other than 1.8.0 are not officially supported.

This could be your antivirus blocking any java installations. Just temporarily disable your antivirus and then try re-adding the openJDK module to your unity installation and it should show the check mark in grey now.

I've solved the problem. with some attached bullshit. You need to do a manual install of this.

Into your empty OpenJDK folder. This is a x64 install which is where my unity installation is. After installing the first portion correctly. If you are prompted for further installs you can cancel the installation. this is a working fix to unitys bullshit.

this fixed for me - recently thank you - putting something in that folder C:\Program Files\Unity\Hub\Editor\2021.1.17f1\Editor\Data\PlaybackEngines\AndroidPlayer\OpenJDK helped with my warning

I solved this by switching off the beta Unity Hub (v3.0) back to the regular one (v2.5.1). I then uninstalled the Unity version in question and reinstalled it with the tools.,I solved it by switching from the beta Unity Hub back to the regular version, then reinstalling the unity version and tools.

I also had 2019.2 already installed when I added 2019.4, and the jdk wasn't installed. I just manually browsed in Unity preferences to the 2019.2 jdk (on a mac, it's /Applications/Unity/Hub/Editor/2019.2.13f1/PlaybackEngines/AndroidPlayer/Tools/OpenJDK/MacOS) so simple fix but annoying.
