ProjectClassPathModifier и ProjectClassPathExtender

0 голосов
/ 25 мая 2018

Я пытаюсь внести исправление в плагин Netbeans 8, который в настоящее время не работает.Плагин включает в себя пункт меню «добавить поддержку», который, помимо прочего, должен добавить запись в путь к классам проекта, если проект является проектом ANT.В настоящее время он делает это вручную, переписывая файл свойств проекта.В некоторых случаях это не удается, например, если у проекта есть выделенная папка библиотеки.Мне удалось написать исправление, которое использует API-класс ProjectClassExtender для добавления библиотеки в класс, но это устаревший API.Я попробовал несколько подходов к работе через замену ProjectClassPathModifier, но я не могу получить правильную комбинацию параметров - я всегда получаю исключение Unsupported Operation или подобное.Может кто-нибудь, пожалуйста, помогите здесь?Приведенный ниже код объединяет три подхода, которые я пробовал: 

        FileObject projectRoot = project.getProjectDirectory();
        Sources sources = ProjectUtils.getSources(project);
        SourceGroup sourceGroup = sources.getSourceGroups(Sources.TYPE_GENERIC)[0];
        FileObject sgRoot = sourceGroup.getRootFolder();
        Library lib = libraryManager.getLibrary(LIB_NAME);
        ProjectClassPathModifier pcpm = projectLookup.lookup(ProjectClassPathModifier.class);
        ProjectClassPathExtender pcpe = pcpm.extenderForModifier(project);
        pcpe.addLibrary(lib); // Works but deprecated
        pcpm.addLibraries(new Library[]{lib}, projectRoot, ClassPath.COMPILE); // Fails regardless
        pcpm.addLibraries(new Library[]{lib}, sgRoot, ClassPath.COMPILE); // Fails regardless

При вызове с использованием projectRoot выдается эта ошибка:

При вызове с использованием sgRoot выдается очень похожая ошибка:

Я думаю, что сам решил проблему и решение: 

        Sources sources = ProjectUtils.getSources(project);
        SourceGroup sourceGroup = sources.getSourceGroups(JavaProjectConstants.SOURCES_TYPE_JAVA)[0];
        FileObject sgRoot = sourceGroup.getRootFolder();
        Library lib = libraryManager.getLibrary(LIB_NAME);
        ProjectClassPathModifier pcpm = projectLookup.lookup(ProjectClassPathModifier.class);
        pcpm.addLibraries(new Library[]{lib}, sgRoot, ClassPath.COMPILE); // works!

Ключ использует тип источника JavaProjectConstants.SOURCES_TYPE_JAVA, а не Sources.TYPE_GENERIC.Generic возвращает основную папку проекта, а вызову addLibraries требуется исходная папка Java.В большинстве проектов это папка src.
