You are right. But please note the following:
I do indeed have the source files in the proper file structure
(corresponding to the package structure). Interestingly this happened after
I re-orgianized the sourcecode, and upgraded Ant from 1.3 to 1.4.1. One of
the major differences regarding sourcecode organization is that I now have
the sourcecode under <project-home>/src/main and <project-home>/src/test.
Packages under 'main' is com.onrelay.*. Packages under 'test' is
test.onrelay.* e.g.
.../JUtils/src/main/com/onrelay/collections/SingleLinkedList.java and
.../JUtils/src/test/test/onrelay/collections/SingleLinkedListJUnitTest.java
Now, my javac task is instructed to compile everything below .../JUtils/src,
and with this setting it won't appreciate that classes in the target
directory is newer than the sourcefiles. However, if I use nested <src>
instead of 'srcdir' then everything works fine.
I consider this a bug in Ant.
Thanx a lot for your valuable help!
