Problem building ant with JDK1.3 modern
I tried changing build.compiler to "modern" in build.xml but the
generated lib\ant.jar is tiny and doesn't contain any classes - just the
properties. The problem's presumably in the javac since the build
directory doesn't contain any classes.
Changing things back to "classic" & running bootstrap brings things back
fine.
Can anybody else replicate this? I am using JDK 1.3 rc1 on NT

No its not a stupid question. The old nightly build process does not
bootstrap ant but simply builds ant with an existing copy of ant itself.
Normally that is OK. If, however, a new feature is introduced into ant and
immediately used in ant's own build.xml file, the old version of ant will
not be able to build the new version. This is why the old nightly build
process is failing.
Sam Ruby has introduced a new nightly build process for ant which bootstraps
ant to avoid this problem. Ant now has its own nightly build which is good.

Conor,
I well realise I was replying to something from 5 months ago - I had to
specifically look it up in the archives :-)
The reason I did so, was because our version of Ant (18th April 2000)
wasn't implementing the modern build. And as far as I could tell from
the archives, there didn't seem to be any follow up to the original
posts.
As you suggested I have downloaded recent (5th July) source and will use
that (it has some olther features I want anyway).
BTW All the recent binaries appear to be zero length .. ? Is this
because of the changes to the nightly builds lately? Soory if this seems
a stupid question, but I'm relatively new to this list.

This has now been implemented. Get the latest nightly build or the latest

Since the distinction between the classic and modern switches for the
Javac task hasn't/can't be implemented, wouldn't it be appropriate to
remove the option in the code and doc?

I'm not sure but it looks to me like com.sun.tools.javac.Main invokes
the "modern" compiler by default. Conversely, I can't see how to invoke
the "classic" compiler.

Oops. This was a skeleton that I stubbed in to be filled in.. It was
before the 1.3 stuff was widely used, so I thought I had time.. Guess
not.
It's easy enough to steal the code from the classic compiler section --
the syntax differences in the command aren't much different. Mainly it's
just a switch in the classname of the entry point
com.sun.tools.javac.Main I beleive.

Doh! I guess I should have looked at the source carefully - this
compiler hasn't been implemented!
May I suggest that someone changes the docs and source in case someone
else falls for it like me...
