[FIXED] TMC beans: The JDK is missing and is required to run some NetBeans modules

Issue

I am new to programming and started the MOOC.FI course (https://www.mooc.fi/en/installation/netbeans) I am running Windows 10. I downloaded both TMC beans 1.4.0, as well as Eclipse Temurin JDK with Hotspot 11.0.12+7(x64).

When I open Netbeans, it says

The JDK is missing and is required to run some NetBeans modules Please use the --jdkhome command line option to specify a JDK installation or see http://wiki.netbeans.org/FaqRunningOnJre for more information.

I tried :

• Uninstalling and redownloading both the JDK and TMC beans.
• Changing the tmcbeans.conf file, changing the file to: #jdkhome="C:\Program Files\Eclipse Foundation\jdk-11.0.12.7-hotspot"
• Adding: netbeans_jkdhome="C:\Program Files\Eclipse Foundation\jdk-11.0.12.7-hotspot"

Both haven't stopped TMC Beans from returning the same message.

EDIT:

The problem is fixed, I downloaded OpenJDK 8 with hotspot from https://adoptopenjdk.net/archive.html?variant=openjdk11&jvmVariant=openj9

Then, I added the line 'jdkhome="C:\Program Files\Eclipse Foundation\jdk-8.0.302.8-hotspot"' to the tmcbeans.conf file. I found it at C:\Program Files\TMCBeans\etc.

After this, the message no longer appears.

Solution

Have you tried downloading the older JDKs from - https://adoptopenjdk.net/archive.html?variant=openjdk11&jvmVariant=openj9?

EDIT 20/08/21 The University of Helsinki is aware of the issue and they are working to resolve it.
