ANT todir= exception
Hello all,
I'm new to ANT. I'm trying to generate checksum using the following syntax,
<checksum algorithm="SHA" file="${build.lib}/app.jar" todir="${build.dest
}"/>
throws
/home/app/build.xml:110: java.lang.NullPointerException
If i remove todir="${build.dest}" parameter, everything compiles.
I'm using Ant 1.6.5 on Sun JDK 1.5.0_05.
Any suggestions?
Thanks,
Chida

The build.xml and the trace is attached. If we confirm this as a bug, I will
file a bug report. Thanks

this is probably a bug in ant. Can you do a -v run and file the trace as
a bug report?
