Ant bug / JavaDoc exception

[Steve Wells <sw...@graviton.com>]

I'm encountering the following exception when trying to have Ant
generate javaDocs under CruiseControl.  The same ant build script works
fine when I'm running from the command line.  Note the long classpath &
the last entry appears to be clipped (C:\dev\gravitonD) though I have
nothing like that (C:\dev\gravitonD) in my path.  When I add exclude
files to the classpath it shrinks the line shown but still has an
abbreviated chunk at the end (with the trailing "D").   Is this a bug
with Ant, buffer sizing problem or command string length limitation,
maybe?

Which probably means it is a javadoc nested into a second project run
by <ant>.

Which is without the intermediate <ant>.

This probably means that Windows doesn't find the javadoc executable.

Could you please replace the version of Ant that ships with CC with
Ant 1.4beta and see whether the problem goes away?

Thanks
