如何通过插件在Eclipse项目中创建包（文件夹）

Question

I try to develop a small plugin for Eclipse to create several Java files in several folders (packages) as a starting point for a new module of a larger software.

I've tried to use an IFile object like this:

final IFile file = container.getFile(new Path(myFileName));
...
file.create(stream, true, monitor);

That works as long as all folders on the path to the file exists. But it does not create any missing folders (new packages) but throws a "resource not exists" exception.

I could not find any way to do this by IResource or IWorkspace objects.

Answer 1

Personally, I use a small method which recursively creates all of the folders, something like:

IFile file = project.getFile(newPath);

prepare((IFolder) file.getParent());

and then the method

public void prepare(IFolder folder) {
    if (!folder.exists()) {
        prepare((IFolder) folder.getParent())
        folder.create(false, false, null);
    }
}

This works well for me.

I know this does not answer your question, but may I suggest you take a look at Maven Archetypes ? This way, you could create project templates with the desired directory structure and boilerplate files, in a configurable and non Eclipse-dependant way.
