multiline output
<echo>
This is only a demo.
Specifically, a demo with an empty line in the middle.
</echo>
... produces different output using ant 1.4.1 or ant 1.5beta1/2:
ant 1.4.1:
> [echo]
> This is only a demo.
>
> Specifically, a demo with an empty line in the middle.
ant 1.5beta2:

> [echo] Specifically, a demo with an empty line in the middle.
I check the changes documentation but couldn't find anything related to
the <echo> task. Is the behavior of 1.5b2 intended? If so, how can I
get a linefeed to appear in the output?
Cheers,
Stefan

A solution for this seems to be to replace the StringTokenizer by
BufferedReader(StringReader(event.getMessage())). Do you want me to
come up with a patch?

Ok, I had a look a org.apache.tools.ant.DefaultLogger.messageLogged():
If -emacs mode is off, a StringTokenizer is used to split the message
into lines. The tokenizer does not return delimiters, which is why
<echo>
Some text${line.separator}
Some more text.
</echo>
does not get you an empty line. Likewise,
<echo>
Some text
${line.separator}
Some more text.
</echo>
does not print the empty line, because the line contains only
"\n\r\n\r" which is skipped by the tokenizer. On the other hand
${line.separator}
results in " \n\r\n\r" and the tokenizer returns the space (" ") and
you get the empty line.
In -emacs mode, the message passed to messageLogged() is simply output.
Conclusion:
The XML parser does not influence the output of the empty line, the
only thing you need is the whitespace in that line, since most editors
remove lonely spaces at line ends, you need something to protect the
space that doesn't print. ${line.separator} or 
 do the job.
Probably a better solution would be to change DefaultLogger to also
print empty lines?

Another strange thing -- your original <echo> task does result in an empty
line in the middle in 1.5 if you include the -emacs command-line flag:
$ ant echoit
echoit:
[echo] This is only a demo.
[echo] Specifically, a demo with an empty line in the middle.
$ ant -emacs echoit
echoit:
This is only a demo.
Specifically, a demo with an empty line in the middle.

Mmh. Strange.
<echo>
This is only a demo.
${line.separator}
Specifically, a demo with an empty line in the middle.
</echo>
..does the job, while
<echo>
This is only a
demo.${line.separator}${line.separator}${line.separator}
Specifically, a demo with an empty line in the middle.
</echo>
does not. Same result with 

Thank you anyway,

Re: multiline output

This is probably due to the change in XML parser that we're using. Have you
tried using a CDATA section? That might fix the multiline output. Or
probably using ${line.separator} (I think) or XML entities (like 
) .
