Providing input with to CVS login
Suppose I want to CVS login to a bunch of CVS repos. I've written a XSL
that generates one target per-repo using code similar to the <exec>
below.
<?xml version="1.0"?>
<project>
<exec executable="cvs" failonerror="true">
<arg line="-d :pserver:foo@bar.lgc.com:/cvs/baz login" />
</exec>
</project>
If I run this on Linux, it works! I.e. I type in the CVS password (which
is not echo'd on the screen BTW), press return, and I get build
successful. The output is a bit garbled, i.e. the prompt for the
password is followed by the info string that should be above. Appendix A
shows the actual output.
The same script on Windows, OTOH, doesn't work. I get the info message,
but whatever I type, nothing happens, and only when I CTRL-C Ant does
the 'CVS password: ' prompt appears, but it's too late. I tried both
terminate yes or no, to no avail.
I then tried to <input> the password (which appears clear text, but I
can live with that...), but then there's no way I can find to pass that
to the CVS login process. Which is confirmed on the command line
independently of Ant, as neither "echo cvspass | cvs -d CVSROOT login"
nor "cvs -d CVSROOT login < cvspassinsidefile" works.
So my question is two fold:
1) How comes it works on Linux and not Windows?
2) Is there any way to do a CVS login using Ant
(that forks cvs) that would work across platform
(assuming the cvs executable is in the path)
Any insight would be appreciated. Thanks, --DD
PS: Didn't someone do something about input Handling in Ant CVS?
Does that go into Ant 1.6.4? And any chance it would held here?

Not directly related to your problem, but "cvs login" needs to be
executed only once. Why do you want to run it from ANT?

Probably because cvs on Linux doesn't use stdin at all. It most
likely reads from /dev/tty directly.

Because it tries stdin - I guess.

<cvspass>?
