trying to compile nutch with ant

[Frank Gunseor]

I am trying to compile nutch using ant with an Ubuntu 8.04 OS.

I keep getting the following error:

BUILD FAILED
/src/nutch/build.xml:443: The following error occurred while executing this
line
/src/nutch/build.xml:409: java.lang.ClassNotFoundException:
org.apache.tools.ant.taskdefs.optional.TraXLiaison

I don't have a clue what to do.

I've checked the documentation, searched the web site, etc.

Can anyone please help?
