Are you compiling from within IntelliJ or from a command line?

rsmckinney commented 2 months ago

If from IntelliJ, make sure your project SDK is setup correctly. Similarly, if building from the command line ensure the right JDK is in context.

sahoomanu commented 2 months ago

Thanks, I am building from command line. GraalVM 21 is set as JDK . looks like conflicting with another dependency library, not sure. able to build the examples given . :(

rsmckinney commented 2 months ago

Is your project available for cloning/debugging? If not, can you provide more details to reproduce the problem? Thanks

sahoomanu commented 2 months ago

no , it is working fine with IntelliJ plugin, not working with maven

--enable-preview --add-exports java.base/jdk.internal.vm=ALL-UNNAMED -Xplugin:Manifold

i tried this , still having issue

rsmckinney commented 2 months ago

I’ll need to reproduce the issue you’re having to make a diagnosis. If your project is not accessible to me, can you refine the problem to a minimum sample project? That help a lot.

I ran into something very similar myself just now. I was following the documentation to create a toy extension. Similar setup to what's listed at the top of this. I am running from IntelliJ and am using java 22. It's completely barebones -- the only thing I have is from the example I was trying to follow.

Here is my repo: https://github.com/cpmooney/example-manifold-extension

The example I was trying to follow along with was here: https://github.com/manifold-systems/manifold/tree/master/manifold-deps-parent/manifold-ext#maven

Here is the output from my compiler:

Hi @cpmooney. I see you've fixed the original issue by adding <maven.compiler.source/target> to your pom file. But your exention for Thing will not work because extensions are exclusive to classes you otherwise cannot modify directly. Since Thing is non-generated and local to the same module in which the extension class is defined, the extension will have no effect on Thing, compiler warnings indicate this.

If instead you define Thing in a separate module, since it compiles separately from your extension, the extension methods will work as expected. You can also add extensions to Java runtime classes such as String and any other class accessible to your project.
