== Known issue on macOS Big Sur 

Apache NetBeans 12.1 fails to run on Big Sur. 

Workaround: edit `netbeans.conf` and uncomment and set the JDK home path in the `netbeans_jdkhome` variable.

----
% ls /Library/Java/JavaVirtualMachines 
adoptopenjdk-11.jdk	adoptopenjdk-8.jdk

% sudo vi /Applications/NetBeans/Apache\ NetBeans\ 12.1.app/Contents/Resources/NetBeans/netbeans/etc/netbeans.conf
----


----
netbeans_jdkhome="/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home"
----

== Deployment platforms

Apache NetBeans 12.1 runs on JDK LTS releases 8 and 11, as well as on JDK 14, i.e., the current JDK release at the time of this NetBeans release.


== Building from source

To build Apache NetBeans 12.1 from source you need:

. A distribution of OpenJDK 8 or 11.
. Apache Ant 1.10 or greater (link:https://ant.apache.org[https://ant.apache.org]).

Once you have everything installed then:

1. Unzip link:https://archive.apache.org/dist/netbeans/netbeans/12.1/netbeans-12.1-source.zip[netbeans-12.1-source.zip]
in a directory of your liking.

[start=2]
. `cd` to that directory, and then run `ant` to build the Apache NetBeans IDE.
Once built you can run the IDE by typing `./nbbuild/netbeans/bin/netbeans`
