i noticed these items over at SUN..
I'm now running everything locally (Ant, JDK, *.java and build.xml), and in a cmd.exe (instead of my cygwin tcsh which sometimes generates path separation issues).
Take a look at the following and tell me if there's any check i'm forgetting:

The javac byte-code compiler has a new -source option that enables support
for compiling source code containing assertions. Also, default compilation
is for -target 1.2. Previously, the default was 1.1. The compiler now
correctly detects unreachable empty statements,and
The Java virtual machines in this release include several enhancements.

New facility for logging garbage-collection events.

Subject: Re: Ant 1.4.1 / JDK 1.4 beta3: '
Some more on this 'Modern compiler is not available / Cannot use classic
compiler' problem:I've been trying Ant 1.4, and JDK 1.3.1_01, local installations iso having
these reside on a SMB server: always the same problem.
I do set JAVA_HOME properly, and setting CLASSPATH to tools.jar doesn't help
either. Building using a minimal build file still gives me the error
message.If i run 'ant -debug', i do get tools.jar in 'java.class.path'.
There must be something very basic that's wrong (some other environment in
this machine / ...) on this Win2k machine.tia,

I looked this up in the archives, and it seems other people had this
problem, but the solution was always adding tools.jar to the classpath (or
setting up JAVA_HOME correctly). I however think these things are fine, and
running ant in debug mode seems to confirm this:Mon 03/12/01 18:55 H:/dev/java
