   I think this is currently possible. If you look at the API you'll see we define a function, getProjectSettings(Uri, string[]) . You can use this with org.eclipse.jdt.core.compiler.problem.enablePreviewFeatures, which is the setting that enables preview features :

   const vscodeJava = extensions.getExtension('redhat.java');
   if (!vscodeJava) {
     throw new Error("VSCode java is not installed");
   }
   
   const api = await vscodeJava.activate();
   if (!api) {
     throw new Error("VSCode java api not found");
   }
   
   const projectSetting: {} = await api.getProjectSettings(
     Uri.file(path.join('some', 'project', 'path')).toString(),
     ['org.eclipse.jdt.core.compiler.problem.enablePreviewFeatures']
   );
   

   I think you would need to ensure that the language server has imported the project, but there are events like onDidProjectsImport that we provide for that also.
