How do I change the hour and minute on a joda time DateTime object?

Question

I've tried the following two options:

        DateTime dt = new DateTime();
        dt = dt.plusDays(1).withMinuteOfHour(0);

and

        DateTime dt = new DateTime();
        dt = dt.withMinuteOfHour(0);

they both report the following error message:

Method "withMinuteOfHour" with signature "(I)Lorg/joda/time/DateTime;" is not applicable on this object

I'm using joda time 2.3:

joda-time:joda-time:2.3

What do you want to change it to ? if the time is say 09:56:35 seconds you want to make it to 09:00:00 ? — StackFlowed, Sep 16 '14 at 19:49
It works fine for me... what's your environment? When are you seeing the error? — Jon Skeet, Sep 16 '14 at 19:51
i'm running in weblogic. right. weblogic uses jodatime 1.2, which doesn't have these methods yet - must be some sort of conflict — blueberryfields, Sep 16 '14 at 19:53
@blueberryfields: Right, that would make perfect sense. It would have been nice to have that information from the start :) I suggest you either edit this question significantly and use 1.2 everywhere, or delete the question while you search for a way of making WebLogic use 2.3. — Jon Skeet, Sep 16 '14 at 19:55

You can also do this

DateTime dt = new DateTime();
dt = dt.minusMinutes(dt.minuteOfHour()).minusSecond(dt.secondOfMinute());

Tracked this to a version conflict between the joda time version included with weblogic, and the one that my application wants to use.

See the answer to this question for ideas for a workaround - solutions #2/#3 in the accepted answer are probably the correct ones to use (and worked for me in this situation).
