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?
