Subject RE: CVS failure notification..
Date Fri, 19 Aug 2005 15:57:40 GMT
Hello,

As far as I can see you are trying to capture the
output of some task and send emails if something goes
wrong. I would suggest to have a look ant loggers and
listeners[1] and especially at MailLogger[2] which
collects the output of the whole build process and
mails it. You can control it to send mails only on
build failures.

Now regarding <javac>: first of all if you want to
process its output you should set its failonerror
attribute to false; by default compile errors fail the
whole build (and it should be so). I also forgot to
tell you there is a <record>[3] task which lets you
record the output of specific parts of the build file.

You already know how to search the output from a task
captured in a file. This may be a tedious process if
you do it for each possible part and investigating
MailLogger in your case may be more useful

Regards
Ivan
