I'll explain a bit more.
I have the following example build.xml file :
<project name="fooproject" default="usage" basedir=".">
<target name="foo">
<copy toDir="targetTree">
<fileset dir="sourceTree" />
</copy>
</target>
<target name="usage">
<echo>foo bar</echo>
</target>
</project>
Project layout looks like this :
testproj
+--- build.xml
+--- sourceTree
+--- bar.txt
+--- subdir
+--- boo.bmp
+--- boo1.bmp
+--- targetDir
+--- <any number of files here>
+--- subdir
+--- otherfile_only_in_target.txt
+--- <any number of files here>
+--- foo1.bmp <== this already exists: error!
Its task is to copy any number of files from sourceDir to targetDir,
but throwing an error if any file to be copied already exists in
targetDir
Here, I need the copy task to fail because subdir/foo1.bmp already
exists. It is possible to do such a thing w/ ant ?
