I don't undstand why I am geting this:
[javac] Modern compiler is not available - using classic compiler
Here is my build.xml

This is the full output:

My path is:
PATH=d:\java\jdk1.4.1\bin;d:\apache\ant-1.5.2\bin
So why does it say "Modern compiler is not available - using classic compiler"?
anyone?
Thanks,

Have you tried setting your JAVA_HOME environment variable as it suggests in the output ?

Hello Andy,
My OS is Win2k with:
Set JAVA_HOME=d:\java\1.4.1
in my system environment.
I have:

in my build.xml and it gives me:
[echo] JavaHome: d:\java\jdk1.4.1
So as far as I can tell I have JAVA_HOME set.
What have I missed?

Try this ..

<target name="compile" depends="init">
<javac srcdir="src"
destdir="build"
classpathref="siacc.class.path"
fork="true"
/>
</target>
ANT-Help....
Windows Note:When the modern compiler is used in unforked mode on Windows, it locks up the files present in the classpath of the <javac> task, and does not release them. The side effect of this is that you will not be able to delete or move those files later on in the build. The workaround is to fork when invoking the compiler.
