Ant 1.6.1 VersionInfo Task

D

Daniel

Hello

I have written a Ant Task which increments a version number by
deserializing an XMLEncoder file and reserializing it after
incrementing. The task is in com.xmatrix.ant.VersionInfoIncrementor
and the VersionInfo class in com.xmatrix.update.VersionInfo. They both
are located in the same JAR! However, Ant (even the newest 1.6.1) does
not find VersionInfo, however it does successfully find the
VersionInfoIncrementor task!

A classpath problem of the strange kind. I would like to understand
this. Any suggestions are welcome.
