現在壊れているNetbeans 8プラグインの修正を提供しようとしています。プラグインには、「サポートを追加」メニュー項目が含まれています。これは、プロジェクトがANTプロジェクトである場合、とりわけプロジェクトクラスパスにエントリを追加するためのものです。現在、プロジェクトプロパティファイルを手動で書き換えることでこれを行っています。これは特定の場合、たとえば失敗しますプロジェクトに専用のライブラリフォルダーがある場合。 ProjectClassExtender APIクラスを使用してライブラリをクラスに追加する修正をコーディングできましたが、これは非推奨のAPIです。交換用のProjectClassPathModifierを使用して作業する方法をいくつか試しましたが、適切なパラメーターの組み合わせを取得できません-常にサポートされていない操作の例外などが発生します。誰かがここで助けてもらえますか? 以下のコードは、私が試した3つのアプローチをまとめたものです。

       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

projectRootを使用した呼び出しでは、次のエラーが発生します。

sgRootを使用した呼び出しは、これと非常によく似たエラーを示します。

  • 私は自分で問題と解決策を解決したと思います:

           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!
    
    

    キーは JavaProjectConstants.SOURCES_TYPE_JAVA を使用しています   Sources.TYPE_GENERIC ではなくソースタイプ 。 Genericはプロジェクトのメインフォルダーを返し、addLibraries呼び出しにはjavaソースフォルダーが必要です。ほとんどのプロジェクトでは、これはsrcフォルダーです。
