1. Download nashorn and some dependencies. You can find these e.g. via https://mvnrepository.com/. Use the maven dependencies to get matching versions. e.g.

   org.openjdk.nashorn:nashorn-core:15.4
   org.ow2.asm:asm:7.3.1
   org.ow2.asm:asm-commons:7.3.1
   org.ow2.asm:asm-analysis:7.3.1
   org.ow2.asm:asm-tree:7.3.1
   org.ow2.asm:asm-util:7.3.1

2. In Netbeans go to Tools -> Options -> Java -> Ant and add the downloaded jar files to the classpath.

That's it.
