You could set another Java TM for NetBeans to develop. You should set The Java TM on Tools>Java Platform,and add the platform you need( you must install jdk8 on your machine),then you could select the Compile JDK for your project in Project Right Click >Build>Compile,Select JDK your want on the selection.then Enjoy your code.as the following picture,you could need.

It never finds any dependencies in the Maven repository, so I always have to add them to the pom.xml manually. I can live with it, although it is a nuisance. Couple days ago I got a to support project, that was created 3-4 years ago in Java 8. The project is in production and working fine, but I do need to make some small changes. The project is not compiling as Java14 does not have a package javax.xml.ws Can someone tell me how can I make Netbeans, which is running on JDK14 to use JDK8 for this particular project? Thank you.
