+ Thanks Conor for your prompt response.
+ 
+ I am not sure if I am seeing normal behaviour from the BuildEvent Listener.
+ Here is what I tried.
+ 
+ C:\play>ant -listener BuildValidate -f test.xml
+ 
+ C:\play>type test.xml
+ <project default="X" >
+         <target name="X">
+                 <copy file="doesnotexist.txt" tofile="doesnotexist2.txt" />
+         </target>
+ </project>
+ 
+ C:\play>dir does*
+  Volume in drive C has no label.
+  Volume Serial Number is 07D1-0208
+ 
+  Directory of C:\play
+ 
+ File Not Found
+ 
+ C:\play>ant -listener BuildValidate -f test.xml
+ Buildfile: test.xml
+ 
+ X:
+      [copy] Could not find file C:\play\doesnotexist.txt to copy.
+ Task has completed successfully   
+ 
+ <mycomment> getException() = null in taskFinished() in BuildValidate</mycomment>
+ 
+ Target has finished successfully
+ 
+ <mycomment> getException() = null in targetFinished() in 
+ BuildValidate</mycomment>
+ 
+ BUILD SUCCESSFUL
+ 
+ Total time: 1 second
+ 
+ C:\play>type test.xml
+ <project default="X" >
+         <target name="X">
+                 <copy file="doesnotexist.txt" tofile="doesnotexist2.txt" />
+                 <ant antfile="test.xml" target="build" />
+         </target>
+ </project>
+ 
+ C:\play>ant -listener BuildValidate -f test.xml
+ Buildfile: test.xml
+ 
+ X:
+      [copy] Could not find file C:\play\doesnotexist.txt to copy.
+ Task has completed successfully
+ Task has completed successfully
+ Target has finished unsuccessfully
+ <mycomment> Both tasks are successful, but the target isn't! </mycomment>
+ 
+ 
+ BUILD FAILED
+ 
+ C:\play\test.xml:4: Target `build' does not exist in this project.
+ 
+ Total time: 1 second
+ 
+ -------------
+ I think, an unsuccessful task is not caught in the taskFinished() method, but
+ is caught in the targetFinished() method which is why you were able to catch 
+ the exception since you implemented it in the targetFinished() method.
+ I intend to catch errors in individual tasks within a target.
+ 
+ Correct me if I am mistaken.
+ 
+ Thanks,
+ Shankar
