When I start Ant in the base directory of Xith3D, I get this error messages :
[root@localhost xith3d]# env JAVA_HOME=/usr ant full
Buildfile: build.xml

setup:

compile:
    [echo] removing out of date files

BUILD FAILED
file:/home/amos/Programmation/Java/Xith3D/xith3d/build.xml:77: Could not create task or type of type: depend.

Ant could not find the task or a class this task relies upon.

This is common and has a number of causes; the usual
solutions are to read the manual pages then download and
install needed JAR files, or fix the build file:
- You have misspelt 'depend'.
  Fix: check your spelling.
- The task needs an external JAR file to execute
  and this is not found at the right place in the classpath.
  Fix: check the documentation for dependencies.
  Fix: declare the task.
- The task is an Ant optional task and optional.jar is absent
  Fix: look for optional.jar in ANT_HOME/lib, download if needed
- The task was not built into optional.jar as dependent
  libraries were not found at build time.
  Fix: look in the JAR to verify, then rebuild with the needed
  libraries, or download a release version from apache.org
- The build file was written for a later version of Ant
  Fix: upgrade to at least the latest release version of Ant
- The task is not an Ant core or optional task
  and needs to be declared using <taskdef>.

Remember that for JAR files to be visible to Ant tasks implemented
in ANT_HOME/lib, the files must be in the same directory or on the
classpath

Please neither file bug reports on this problem, nor email the
Ant mailing lists, until all of these causes have been explored,
as this is not an Ant bug.

Depend is a great feature of ant which determines which class files are out of date and need to be recompiled.  The alternative is "ant clean" which whipes the lot causiong the compilation to take much longer.  Depend does a lot more than just removes files whose .java files have been changed because there are some cases where recompilation is needed even when the parent .java file is unchanged.

If depend isn't working - I'd try an "ant clean" once to remove any objectionable class files.  Otherwise try reinstalling ant.

Will.
