ProjectClassPathModifier和ProjectClassPathExtender

标签： netbeans netbeans-plugins netbeans-8.2

我正在尝试为Netbeans 8插件做出贡献，该插件目前已被破坏。该插件包含一个＆＃34;添加支持＆＃34;菜单项，除其他外，如果项目是ANT项目，则应该在项目类路径中添加一个条目。目前，它通过手动重写项目属性文件来完成此操作。在某些情况下失败，例如如果项目有专用的库文件夹。 我设法编写了一个修复程序，它使用ProjectClassExtender API类将库添加到类中，但这是一个不推荐使用的API。我已经尝试了几种通过替换ProjectClassPathModifier工作的方法，但我无法获得正确的参数组合 - 我总是得到一个不支持的操作异常或类似的。有人可以帮忙吗？ 下面的代码浓缩了我尝试过的三种方法：

        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

使用projectRoot的调用会出现此错误：

使用sgRoot进行的调用给出了类似的错误：

我想我自己已经解决了问题和解决方案：

        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!

关键是使用JavaProjectConstants.SOURCES_TYPE_JAVA来源类型，而不是Sources.TYPE_GENERIC。 Generic返回项目主文件夹，addLibraries调用需要java源文件夹。在大多数项目中，这是src文件夹。
