In this post, I will show you the steps to change JDK for Apache NetBeans IDE. In other words, how to run NetBeans under different version of JDK.

You know, by default, NetBeans IDE sticks with the JDK it found at the time of installation, by storing the path to JDK home in a configuration file called netbeans.conf. You can find this file under NetBeans installation directory > netbeans > etc directory.

For example, if you install NetBeans on Windows, you can find this configuration file under this directory:

C:\Program Files\NetBeans-VERSION\netbeans\etc

Then open the netbeans.conf file using a text editor. Look for the line that looks like below:

netbeans_jdkhome="g:\JDK\OpenJDK\jdk-11.0.2"

Then update new value for this property, for example:

netbeans_jdkhome="C:\Program Files\Java\jdk-14"

Save the file and restart NetBeans. And you’re all set. The Apache NetBeans IDE will run under the specified JDK.

So to change JDK for NetBeans, to update the netbeans_jdkhome property in the netbeans.conf file which can be found under installation directory > netbeans > etc directory.
