I have JDK 15.0.1 and I've installed Netbeans 12.1 with it.
I am having significant trouble trying to open up a project because it gives me these error messages when I reach the section 'Finding Feature'
"Cannot enable Java Persistence, Spring Beans, Gradle, Java, Java SE Modular Projects, Java Debugger, Maven, GUI Builder, GraaIVM Debugging Support"
I have tried every tutorial possible on here and on YouTube and I just can't seem to get past this part.
I solved it like follows:
Check where is your netbeans.conf file located by typing
locate netbeans.conf
Once you got your conf file location you will have to edit it by using your favourite editor like:
sudo nano <.../path/netbeans.conf>
In this file you got to change the line referring to your java installation for example:
netbeans_jdkhome="/Library/Java/JavaVirtualMachines/jdk-10.jdk/Contents/Home"
