Subject Re: Error returned using <exec> task
Date Fri, 25 Jul 2008 14:58:17 GMT
First, let me apologize for the lengthy code.  I was trying to put in as 
much information as possible.

I'm actually trying to run this on a UNIX server.  I'm new to the UNIX 
environment, so correct me if I am wrong, but if I use the bash command, 
will I not have to create and execute some sort of shell script?  If this 
is the case, I'm not sure if this will work for me.  All I am trying to do 
is execute a the cvs status command.  Below is what I am trying to 
accomplish if I was doing this from the command line:

        cvs -d :pserver:user@mycvsrepository.net:cvs/build/logs status 
opt/usr/bin/testfile.xml

This will return the following info:

 ===================================================================
        File: Demo.xml          Status: Up-to-date

        Working revision:    1.8
        Repository revision: 1.8 
/cvs/1LCW-LiveCycle_Workflow/1LCW_Pilot/Customer/Demo/Demo/Demo.xml,v
        Sticky Tag:          c0467215_1LCW_Demo_07-22-08_1300_ReadyITE 
(revision: 1.8)
        Sticky Date:         (none)
        Sticky Options:      (none)

All I am trying to get is the Working revision line and place it into a 
property.  The following line:

        cvs -d :pserver:user@mycvsrepository.net:cvs/build/logs status 
opt/usr/bin/testfile.xml | grep 'Working'

returns this:

        Working revision:    1.8

I'm trying to take the line above and place it into a property so I can 
later parse it to find the latest revision number.  Hopefully, this helps 
and clarifies what I am doing.

Thanks,

Re: Error returned using <exec> task






The code pieces You pasted are quite lenghty, and most of my experience
comes from unix boxes, but I guess there might be a similarity.


<exec executable="cvs" failonerror="true"
outputproperty="build.xml.
>
> version.line">
>                       <arg line="-d${common.setup.cvsRoot} status
> ${app.lar.source.clientpath/${prop.cust.xml.basename}.xml | grep
> 'Working'"/>


This has no right to do whatever it is You want it to - at least on linux 
it
wouldn't. There's an explanation on the ant website somewhere, so I won't
repeat all of it. In brief - if You want to pipe output to another 
program,
You'd have to exec not the command You want, but the command environment. 
So
in my case this usually was something like:

<exec executable="bash"><arg line="-c 'do_stuff |
do_some_more_stuff'"/></exec>

Otherwise the redirection of output/error streams doesn't work. At least
that's on linux, but I imagine it will be the same on windows. Besides 
this,
I don't see why You might not be getting what You want. Hope I helped a
little.

Cheers,
Chris
