Need help running Ant under cygwin on Win2k
I'm trying to run Ant 1.5beta2 on a Windows 2000 machine under Cygwin. I've
installed Ant and JDK 1.4 in the Cygwin paths (/usr/local) as I saw someone
suggest in the mailing list archives, and set my ANT_HOME and JAVA_HOME to
those. However, whether I do it that way, or just have Ant and JDK
installed under normal Windows locations (and thus set ANT_HOME to something
like /cygdrive/c/ant), I get the following error message when running Ant:
Exception in thread "main" java.lang.NoClassDefFoundError: and
If I run Ant at a normal DOS prompt, it runs fine. Anyone have any ideas on
how I can fix this?

The JDK *is* a real windows App and therefore Ant under that JDK,
regardless of whether you started it with cmd.exe or cygwin, thinks it
is running on Windows - which it is :-)
IOW, JDK is not linked against Cygwin.

a) yes you can, already explained
b) add it to the PATHEXT env variable, and you can go "somescript" on the
command line and have the perl file executed.

I use ActivePerl as well, but I can't just run "somescript.pl" from a DOS
prompt on Windows. So, I would need to change my Ant files to do "perl
somescript.pl", which is not a big deal, but is ugly.

That's why I also suggested using <env> instead, so you could include the
dir the script lives in when you run your <exec>.
To make the whole thing platform-independent, you'd want to set up a
<path> based on where the script lives plus your PATH env var (so you'd
need to do a <property environment=.../>), then <pathconvert> that <path>
into a property, and reference that property in the 'value' for the <env>.
For example:
<property name="filename" value="src/lib/foo.a"/>
<property environment="env"/>
<path id="path" path="${env.PATH}:${env.TEMP}/bin"/>
<target name="main">
<pathconvert pathsep="${path.separator}" refid="path"
property="path"/>
<exec executable="sh">
<arg line='-c "printit.pl ${filename}"'/>
<env key="PATH" value="${path}"/>
</exec>
</target>

Putting it in the path is not really acceptable. It's a script that is
specific to our build environment (it's a compiler we wrote), so IMHO, it
has no business being on the general path environment variable. Plus, as
soon as I require it to be on the path, that's just one more thing folks
would have to set up and have right, as opposed to simply being able to
check the whole thing out from CVS and just do "ant" and get it to build.
Another consideration was to define something like a $PROJECT_HOME
environment variable, and then use the "value" attribute with property
definition (instead of "location"), and prefix everything with
$PROEJCT_HOME. The only problem with this is that we might have multiple
sandboxes for the project (say to work on various branches or for testing or
whatever), and then I'd have to constantly update my $PROJECT_HOME to make
it work right.
Heh, all this so some poor guy can build on a Windows box ;)

I don't find it painful at all. I've been doing it for over a year -- it's
what I create all my brilliant solutions to ant-user on :)
After I sent that mail last night, it occurred to me that you weren't
setting a property you were going to pass as an arg to your script, but
rather you were pointing to your perl script itself with the property.
That, you don't need to do at all -- just make sure where it lives is
included in your PATH (or try passing it in an <env> -- I don't have time
this morning to experiment).

So, this makes the whole "location" property thing more painful then. If I
use "value" instead, then the value of the property is just what I type, so,
below the "bin" property will just be "bin", as opposed to doing a relative
path resolution to wherever the bin dir is located.
At this point, it seems fairly painful for me to run Ant under Cygwin. I'm
not blaming Ant, as it really is a combination of the JDK, ant, some crappy
scripts we have that need full paths and so on. Windows of course makes it
even worse, because I can't simply run a Perl script as I do on a UNIX box.
This was one of the reasons I figured we'd use Cygwin in the first place.
Oh well.

Ok, the cygwin.home.user works. But, the slashes seem to be the opposite
behavior. For example, I set a property for a Perl script we run, as this:
<property name="bin" location="bin"/>
<property name="wmdl.compiler" location="${bin}/wmdlcc.pl"/>
Then I exec ${wmdl.compiler}, but what I see Ant 1.5Beta2 spit out is:
BUILD FAILED
C:\cygwin\home\crb\wego\build.xml:265: Execute failed: java.io.IOException:
Crea
teProcess: C:\cygwin\home\crb\wego\bin\wmdlcc.pl error=193
So, Cygwin/Ant is using backslashes. It's also sticking the C: in there.
It's as if it's behaving as a real Windows app. Do I not have something
configured correctly?

$USERPROFILE is set by WinNT/2000/XP in cmd.exe based on the locaton of
your user profile. Cygwin is inheriting the existing value when starting
bash.

The user.home property is set by the JVM, not by Ant.

You shouldn't change it because it could cause the JVM to fail upon
startup. Remember, a Windows JVM does not understand Cygwin paths. Since
Ant is running under such a JVM, it can't understand Cygwin paths either.
However, forward slashes "/" are okay with the exception that if you
<exec> an external program, it may not support them in any arguments.
The ant script in 1.5B2 defines the system property cygwin.user.home which
is $HOME converted to a Windows format path. If you set $HOME to the
desired Cygwin path before starting Ant, you can reference that path
within you build.xml as ${cygwin.user.home}.
Hope this helps,

Never mind. Of course immediately after I post I finally figured it out.
My $HOME was set to C:\Documents and Settings\crb\My Documents. Obviously
it didn't like that path with the spaces and such.
