Sounds good. In that way eg the optional tasks could print their needed
libraries when not present.
E.g.:
script: No scripting engine available - install BSF or use Java 6. See
manual/install...

Add an empty
public void diagnostics(PrintStream) throws BuildException
method to Task?
Mmh ... I would prefer a helper object
Task {
public void diagnostics(DiagnosticsHelper) throws BuildException
}
DiagnosticsHelper {
write(PrintStream) // direct access to output
write(Object) // direct access to output
newLine() // prints a new line directly to output
print(Object) // handles indents and prefixes
setPrefix(String) // the prefix to use; set while processing the
several tasks
}

While I think that it's a good idea to narrow the output I dont like
that kind of parameters:
> ant -diagonistics -task junit
"junit" would normally be the name of a target ...
What about special properties? ant.diagnostics=junit
Ok, your way would be easier for the user ....
When using -diagonistics, do we process the target names? If not why not
simply use
ant -diagonistics
ant -diagonistics junit
ant -diagonistics antlib:org.example.something
or in combination
ant -diagonistics junit antlib:org.example.something copy ...
