NetBeans default JDK for me is JDK20 and this incubator module has been available since about JDK17, so it should be in there.
My problem is strictly compiling right now and this is my modulue's project.properties file: javac.source=20 javac.compilerargs=-Xlint -Xlint:-serial --release 20 --enable-preview --add-modules jdk.incubator.vector Interesting though that this message appears in several places in the compiler warning messages: warning: using incubating module(s): jdk.incubator.vector In the offending class file, this import statement import jdk.incubator.vector; has tooltip messages that package jdk.incubator does not exist. A search for module dependency does not provide any suggestions. A typical line of code that does not compile or have import suggestions is: VectorSpecies<Float> species = FloatVector.SPECIES_256; I also added "--enable-preview --add-modules jdk.incubator.vector" to the default_options assignment in my app.conf file. I'm sure there must be some little thing I'm missing. -----Original Message----- From: Jerome Lelasseux <[email protected]> Sent: Wednesday, October 22, 2025 11:02 AM To: stephen cumminger <[email protected]> Subject: Re: Using Java Incubator features in NetBeans RCP Application My JJazzLab rcp app (maven) uses the JDK17 "Foreign" incubator feature in one module. I just checked, I use the same flags than you and it works fine. Are you sure to use the right JDK version ? You can't use a java 17 incubator feature using JDK18 (even with --release 17).

I am using NB20 and getting compile errors that can’t be resolved. Specifically I am trying to use jdk.incubator.vector to access faster SIMD instructions. In the module where I am trying to use this, I have the following in its project.properties file: javac.compilerargs=-Xlint -Xlint:-serial --enable-preview --add-modules jdk.incubator.vector I also have in the project.properties file for the master project as run.args.extra … -J--enable-preview -J--add-modules=jdk.incubator.vector I’ve gotten several suggestions via Google, but I think I am looking for a way to get NetBeans to fully compile and allow to run with these incubator features. Any suggestions?
