Waf: target is directory

My wscript file is simple:

def configure(ctx):
    pass

def build(bld):
    bld(rule='mkdir aaa', target='aaa')
    bld(rule='touch bbb', source='aaa', target='bbb')

And first run of waf configure and waf build passes OK. But the second waf build fails with an error:

source not found: 'aaa' in bld(source='aaa', target=['bbb'], meths=['process_rule', 'process_source'], features=[], path=/home/rnd/prj/prj2/prj-web, idx=2, tg_idx_count=2, rule='touch bbb', posted=True, _name='bbb') in /home/rnd/prj/prj2/prj-web

But if to change the "mkdir" to "touch" - everything works as expected. How to use a directory as a target? (PS. It would be interesting is it possible to use it as a source as well), because it's easy in a plain Makefile, so I had feeling that Waf can handle directories too.

Well, the waf model don't manage directories with the source and target keywords. You can handle directories with specific keyword of your own, like source_dir and target_dir. Like :

def my_rule(task):
    tg = task.generator
    target_dir = tg.path.get_bld().make_node(target_dir)
    target_dir.mkdir()
bld(rule=my_rule, target=dir = "bbb")
