The answer helped me launch Netbeans from the terminal. I added this change to make my dock icon launch Netbeans like before.
I changed the Netbeans config file to make it launch with the Java path:
- Like the previous post indicates find your JDK path with this command in the Terminal
/usr/libexec/java_home -v '1.7*'
- Now add this path to the Netbeans conf file. To do this:
- right click on the Netbeans icon in the dock and select Open in Finder
- in the smaller icon it shows right click again and select Show sources
- find the netbeans.conf file in folder Resources/NetBeans/netbeans/etc/netbeans.conf
- open this netbeans.conf file with a TextEditor or similar and find the line
#netbeans_jdkhome="/path/to/jdk"
Uncomment this line and change it for your path (the one you found in point 1) something like
netbeans_jdkhome="/Library/Java/JavaVirtualMachines/jdk-15.jdk/Contents/Home"
Save the netbeans.conf file and try and launch from the Dock icon

If you right click on the icon in the dock --> Options --> Show in Finder the operating system will show you where 'Apache Netbeans 12.0' is located.
Highlight 'Apache Netbeans 12.0' then right-click and choose 'Show Package Contents', then you can find a shortcut that launches Netbeans (Contents/MacOS/netbeans).
If you double-click to launch netbeans you'll be presented with the following reason why it fails to load.
/Applications/NetBeans/Apache\ NetBeans\ 12.0.app/Contents/Resources/NetBeans/netbeans/bin/netbeans ; exit;
rob@Robs-MBP-2015 ~ % /Applications/NetBeans/Apache\ NetBeans\ 12.0.app/Contents/Resources/NetBeans/netbeans/bin/netbeans ; exit;
The operation couldn’t be completed. Unable to locate a Java Runtime that supports (null).

Cannot find java. Please use the --jdkhome switch.
Credit goes to How can I change Mac OS's default Java VM returned from /usr/libexec/java_home for providing the following step to determine what the JDK path is...
/usr/libexec/java_home -v '1.7*'
Then you can type the following (adjust for your path and version required)
export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk-13.0.2.jdk/Contents/Home"
However that didn't seem to do the trick for me (I also tried JDK_HOME), so instead from a Terminal window type the command to launch Netbeans but include the --jdkhome to your Java home folder, e.g.
/Applications/NetBeans/Apache\ NetBeans\ 12.0.app/Contents/Resources/NetBeans/netbeans/bin/netbeans --jdkhome /Library/Java/JavaVirtualMachines/jdk-13.0.2.jdk/Contents/Home
Now I have Netbeans launching again. I'm not quite sure why the JAVA_HOME doesn't resolve this, but hopefully in the meantime anyone unable to launch Netbeans can at least use this workaround.
