Intermittent problem with input task
I've been having an intermittent problem with the 'input' task for the past
several days. I'm baffled by what causes it and would like to know if anyone
else has seen this or knows of a solution/workaround to keep it from
happening?
I'm using Ant 1.6.5 in Eclipse 3.1.1 and my problem is simple: my 'input'
task _occasionally_ fails to bring up the input dialog. Even with -verbose
and -debug in my startup parameters, the Ant output simply shows the name of
the target that contains the input task with no other output, like so:
getserver:
The build doesn't seem to succeed _or_ fail; there is nothing after the
'getserver:' line. However, the build seems to have ended because I can
launch it again without a problem.
I was getting this problem very persistently a few days ago, then it went
away suddenly. Now it is back. I can't think of anything I have done in my
build script or my environment to cause my 'input' task to work or fail
intermittently; the target is itself has been working unchanged for a couple
of years until this problem started the other day. Here is the target:
<target name="getserver" description="Determine which server is the target">
<input message="Which server should receive the files? 1. Silo 2. Bongo"
validargs="1,2"
addproperty="server.choice"
defaultvalue="2"/>
<condition property="servername" value="Silo">
<equals arg1="${server.choice}" arg2="1"/>
</condition>
<condition property="servername" value="Bongo">
<equals arg1="${server.choice}" arg2="2"/>
</condition>
</target>
Can anyone help me figure out how to get the 'input' task working _all_ of
the time? This is really messing me up. I have several input tasks to prompt
for input that should not be hard-coded in the script for security reasons.

Hello Rhino,
If the property server.choice is set, the input task
will be skipped. Well, it might be not your case -
just be sure that you do not set server.choice in
advance.
Also can you run your script from the command line -
if it works correctly than the problem is in Eclipse.
There is some machinery behind <input> task. It does
not read directly from System.in (the standard input
stream); instead it delegates reading the input to the
so called InputHandlers (part of Ant API). I think
that Eclipse has its own InputHandler which pops up an
dialog - I have never used him and never read its code
so I am not sure how it works. I hope some of the
Eclipse guys here will be able to help you more.
Regards
Ivan
