How can i convert a FilePath to a File?

Question

I'm writing a Jenkins plugin and i'm using build.getWorkspace() to get the path to the current workspace. The issue is that this returns a FilePath object.

How can i convert this to a File object?

Please use the act function and call your own FileCallable implementation if your plugin should work for master and slaves. For more information check the documentation, chapter "Using FilePath smartly" or this stackoverflow answer.

Code example (source):

void someMethod(FilePath file) {
    // make 'file' a fresh empty directory.
    file.act(new Freshen());
}
// if 'file' is on a different node, this FileCallable will
// be transferred to that node and executed there.
private static final class Freshen implements FileCallable<Void> {
    private static final long serialVersionUID = 1;
    @Override public Void invoke(File f, VirtualChannel channel) {
        // f and file represent the same thing
        f.deleteContents();
        f.mkdirs();
        return null;
    }
}
