NetBeans 12.0 LTS - Hibernate Plugin require Freemarker Integration implementation version 238

Question

In Apache NetBeans 12.0 LTS

When I'm trying to install Hibernate plugin it says :

Some plugins require plugin Freemarker Integration to be installed

The plugin Freemarker Integration is requested in implementation version 238.
The following plugin is affected:

Hibernate

But there's on Apache NetBeans Plugin Portal Freemarker plugin is not available.

I tried installing Freemarker plugin from old plugin portal of NetBeans

FreeMarker support for NetBeans

but getting same error.

I'm using:

Debain 10.4 Buster LXQt AMD 64-bits  
openjdk 11.0.7 2020-04-14 LTS
Apache NetBeans 12.0 LTS

I've also created issue there at Apache's JIRA issue tracker
No dependent plugins are available at Apache NetBeans plugin portal for Hibernate

But I think they will not pay attention.

This causes because there is a conflict for the version of freemarker, netbeans is looking for freemarker.jar with OpenIDE-Module-Implementation-Version: 238, but in my case the OpenIDE-Module-Implementation-Version: was 239 and that was causing the issue.

You can fix this by

Close your running netbeans application
Download freemarker.jar with OpenIDE-Module-Implementation-Version: 238 org-netbeans-libs-freemarker-RELEASE81.jar and rename the downloaded library to org-netbeans-libs-freemarker.jar
Navigate to ide/modules subfolder in apache netbeans installation directory
You will find the freemarker library org-netbeans-libs-freemarker.jar, replace this with your downloaded library.
Restart the netbeans(or perhaps restarting the computer should work) and you should be able to download the hibernate plugin

ps- you can check the OpenIDE-Module-Implementation-Version by opening the jar library as an archive and inside the META-INF/MANIFEST.MF file
