For the record, I think it's bad Ant style to use ids in tasks. This
is kept around for BC, but should be discouraged. Using ids on types
OTOH is OK, and essential to types in fact. If a task should refer to
part of another task's internal config, this hints to the config
needing to be its own type referred to by both tasks. It's even OK for
the type to be implicitly created by the first task, when it receives
for example a configid="foo" attribute, so that the second task can
use it using configrefid="foo" or a nested <config refid="foo" />.
I'm not sure how Ivy does it exactly, but somehow I got the feel from
the discussions that it's using the "deprecated" id'd task pattern,
which is a "bad" pattern IMHO. Hopefully I got the wrong feeling ;-)

We can put a reference to the bug, the problem occurs only when you call ant
with multiple targets, each depending on the same settings, so I think
people can use Ivy settings with with ant 1.7.0 without running into the
problem.

I don't think so, I've already tried to find something but I haven't found.
But since ant 1.7.1 will be out pretty soon, if the fix is included I don't
think it's worth investigating more on Ivy side.

+1 for me as well (let's put a little bit more presure from the Ivy guys ;-).
To come back to the impact on Ivy, I think we should put a note in our
doc saying that using the settings task with an id requires 1.7.1.
Or is there any workaround we could implement in ivy settings task ?

We won't need any other change in Ant for Ivy 2.0.0, and don't even need
this fix to be applied. So don't do it only for Ivy.

Hello Kevin,
great work.
I have switched my project to use the 1.7.1beta for all builds already and it is working great.

The change to UnknownElement is now merged back into BRANCH_17
I will test on windows/ubuntu at some point this week - then I suppose
a further vote on the new srcs before releasing a further beta

The problem showed up as a symptom in Ivy but Ivy isn't the only one
affected by it. I'm all in favor of merging the change regardless.

Does this mean that you would like to change anything or should I
merge this change into 1.7.1 now? I'd rather merge something into
1.7.1 that fixes the problem for ant, and is going to require no
further changes in the future to support Ivy

Note that according to recent discussions on the subject, we will most
likely drop the use of 'id' on the task used to load the settings (which
will probably be 'configure' again, since I seem to be the only one who
don't like using configure where we have make a lot of effort to drop the
confusing 'configuration' in favour of 'settings'). Hence this bug shouldn't
hurt Ivy users in Ivy 2.0 final.
That doesn't prevent fixing the bug in Ant 1.7.1 final, but don't do it only
for Ivy users.

Looks pretty save to me. This means we might be having a few
tasks/types living longer than needed, but it seems to be the only way
people can use ids in their build files and run multiple targets at
the same time.
