Subject Re: <input>, but for paths...
Date Wed, 15 Feb 2006 18:11:32 GMT
Hello,

<input> task does not read the user input. Instead it
delegates the reading to InputHandlers [1]. In short
you should write an extension of InputHandler and
create the dialog in it. Then pass the fully qualified
name of your input handler to -inputhandler option of
ant launching script. I collected some more
information on ant's input handlers in an article
called "Extending Ant Input Abilties", which you can
find at [2].

While it is a good exercise to play with the handlers,
I think that <input> task spoils the idea of the
automation. I prefer to store the different settings
in  differen properties/xml files and load one of
those files depending on the context/environment of
the build. Of course, if in your case the path is
completely arbitrary, you have less choices.

Regards
Ivan
