Eclipse插件：扩展INewWizard的新文件向导，如何在其中创建所选项目

Question

I'm currently writing an eclipse plugin, and in it, I have a new project creation and a new file creation wizard.

In the new project wizard, I create it, so I have no problem getting it and creating new files in it. (like creating the Main class for your project)

But when I'm in my New file wizard, I have literally no idea how to select the right project, and I would like some help please. Since it is a wizard, I would like to avoid needing an opened editor, and since it's a new wizard, it doesn't have a handler so I can't get it from there...

Thank you in advance, Cordially,

Okay, I looked at it from another approach and it feels quite stupid right now.

When you initialize your wizard, you get an init method that contains the workbench and the selection, so you can keep it.

private IWorkbench wb;
private IStructuredSelection sel;
@Override
public void init(IWorkbench workbench, IStructuredSelection selection) {
    wb = workbench;
    sel = selection;
}

Then, I had found a code snippet earlier on Eclipse website, linked under here, that I had to change a bit, and it does what I want it to do.

// Get selected resource (can get project from it)
// https://wiki.eclipse.org/FAQ_How_do_I_access_the_active_project%3F
private IResource extractSelection() {
    Object element = sel.getFirstElement();
    if (element instanceof IResource)
        return (IResource) element;
    if (!(element instanceof IAdaptable))
        return null;
    IAdaptable adaptable = (IAdaptable)element;
    Object adapter = adaptable.getAdapter(IResource.class);
    return (IResource) adapter;
}

With this, I can get my project in my wizard by doing

IProject project = extractSelection().getProject();
