JavaFX Modular项目问题

如何解决JavaFX Modular项目问题

我有gluon Mobile示例项目，并决定通过添加module-info.java类使其模块化，此后我一直收到许多程序包错误，例如：

error: package com.gluonhq.attach.util.impl is not visible
package com.gluonhq.attach.util.impl is declared in module com.gluonhq.attach.util,which does not export it
package com.sun.javafx is declared in module javafx.base,which does not export it to module Simple
package com.sun.javafx is not visible
package com.sun.javafx is declared in module javafx.base,which does not export it to module Simple
...

自从我在main()方法中添加了以下代码段后，问题就开始了：

if(isWindows() || isMac() || isUnix()) {
            System.setProperty("javafx.platform","Desktop");
        }

        // define service for desktop
        StorageService storageService = new StorageService() {
            @Override
            public Optional<File> getPrivateStorage() {
                // user home app config location (linux: /home/[yourname]/.gluonmaps)
                return Optional.of(new File(System.getProperty("user.home")));
            }

            @Override
            public Optional<File> getPublicStorage(String subdirectory) {
                // this should work on desktop systems because home path is public
                return getPrivateStorage();
            }

            @Override
            public boolean isExternalStorageWritable() {
                //noinspection ConstantConditions
                return getPrivateStorage().get().canWrite();
            }

            @Override
            public boolean isExternalStorageReadable() {
                //noinspection ConstantConditions
                return getPrivateStorage().get().canRead();
            }
        };

        // define service factory for desktop
        ServiceFactory<StorageService> storageServiceFactory = new ServiceFactory<StorageService>() {

            @Override
            public Class<StorageService> getServiceType() {
                return StorageService.class;
            }

            @Override
            public Optional<StorageService> getInstance() {
                return Optional.of(storageService);
            }

        };
        // register service
        Services.registerServiceFactory(storageServiceFactory);

应该解决这个问题，并避免一些小事，这些事以后会成为大问题：

Sep 21,2020 2:09:35 PM com.gluonhq.attach.util.Platform <clinit>
INFO: javafx.platform is not defined. Desktop will be assumed by default.

请帮助！
