One observation

[Bhushan Jawle]

I have been using Ant with Eclipse and Netbeans.
The same directory structure(with directories as src, build, config etc.) and same build file . The o/p directory specified is build.
After compiling the code in Eclipse, I have observed that Eclipse creates a NEW directory structure matching the directory structure of the directory in which build.xml resides under the target directory.
There is a high possibility that I am doing something wrong here, but when I delete the directory structure created, and compile the same code using same build.xml in NetBeans it works as expected. Has anybody come across this ?
What am I missing ?

Anybody, any views ?

I'm guessing that the directory you are seeing is being created when Eclipse compiles the code directly, not using Ant. You should be able to check this out by:

start Eclipse

open your project (if it's not already open), and select it in the "package explorer".

delete the offending directories from outside Eclipse

click project :: rebuild project

If this is the problem, your troublesome directories should reappear.
One way to stop this bothering you is to tell Eclipse to put its class files somewhere else:

click project :: properties

select "java build path"

put an out-of-the-way directory name in the box at the bottom (say /tmp/eclipse/projectname )

click OK

Now you should be able to rebuild whenever you like, without Eclipse messing with your build area.
Has this helped?
