Good Afternoon Martin,

I'm not sure what version of Ant you are referring to because the newer
versions (1.6+)
have the -lib command line option to add to the classpath (See
http://ant.apache.org/manual/running.html)

As I said below my build script works fine when any of the output
options (-debug, -verbose, -quiert etc.) are turned on -- the taskdef
classes are all found and execute correctly and the build works.

It's when I turn these options off for "normal" operation that I get the
class not found errors.

I don't understand the why output options should affect taskdef
behaviour in  this way.

I'm trying to avoid explicitly specifying classpaths for taskdefs for
"out of the box" tools like hibernate and xdoclet. I want to control the
verion used from the ant command line by means of the -lib directive.

Good Morning Gary-

This is my understanding for ensuring classpath is updated for taskdef 

Taskdef CLASSPATH
  if no CLASSPATH available acquire from

Target classpath
 if no CLASSPATH available acquire from

Project classpath (build.xml) CLASSPATH variable  if no CLASSPATH
available acquire from

System level CLASSPATH (usually environment variable)

if you are able to locate the jars that contain the hibernate classes if
you want my 2 cents I would make sure the CLASSPATH on taskdef is known-
http://ant-contrib.sourceforge.net/

Let me know if you have any questions
Thanks,
Martin --

All,
 
I am using ant 1.6.5 with the following command line on Windows XP Pro:
 
call %ANT_HOME%\bin\ant -quiet -noclasspath -nouserlib ^
-lib tools\xdoclet-1.2.3\lib ^
-lib tools\hibernate-3.1 -lib tools\hibernate-3.1\lib ^
-lib lib\ext\j2ee-1.3 -lib libtest\junit3.8.2 -lib tools\bcel-5.2
 
and my build works fine.
I can substitute "-debug" "-verbose" or "-logfile" for "-quiet" and it
still works.
 
However if I leave "-quiet" out altogether the taskdefs such as these:
 
  <taskdef name="hibernatedoclet"
            classname="xdoclet.modules.hibernate.HibernateDocletTask"/>
  <taskdef name="ejbdoclet"
           classname="xdoclet.modules.ejb.EjbDocletTask"/>

all fail with the message:
C:\clearcase_snapshots\ghoward_view\celona_software_dev\build.xml:402:
The following error occurred while executing this line:
C:\clearcase_snapshots\ghoward_view\celona_software_dev\build.xml:525:
taskdef class xdoclet.modules.hibernate.HibernateDocletTask cannot be
found
 
Can someone explain how (and why) the output options are apparently
affecting the taskdef classpath?
