How to programmatically copy a folder from a plugin to a new project in the work space?

Question

I am developing an Eclipse Plugin creating a new Project Wizard. When creating such new project in the workspace I need it to copy a folder, and its descendent, from the plu

Answer 1

This is not possible without knowing exactly the files (you cannot iterate over the children). Instead of using a folder with files and subfolders, create a zip with that structure and unpack the zip in your workspace (this should preserve the desired structure).

Answer 2

Check out this answer to see how to get a file/folder "out of" a plugin.

Then create new files/folders in the projects and set file contents using InputStream:

void copyFiles (File srcFolder, IContainer destFolder) {
    for (File f: srcFolder.listFiles()) {
        if (f.isDirectory()) {
            IFolder newFolder = destFolder.getFolder(new Path(f.getName()));
            newFolder.create(true, true, null);
            copyFiles(f, newFolder);
        } else {
            IFile newFile = destFolder.getFile(new Path(f.getName()));
            newFile.create(new FileInputStream(f), true, null);
        }
    }
}
