Well, in some twisted way, yes. The XmlLogger does two things: recording
seen tasks in "tasks", and recording timing info. When created inside the
build script, some info is missing ('cause of missed events), leading to the
RuntimeError and a NullPointerExeption. Which is why this thing works:
<?xml version="1.0" encoding="ISO-8859-1"?>
<project name="logger.test" default="test" basedir=".">

Test Adding Logger via Scripting
</description>
<property name="XmlLogger.file" location="ant.log.xml"/>
<script language="jython"><![CDATA[if 1:
from org.apache.tools.ant import BuildEvent, XmlLogger
class TardyXmlLogger(XmlLogger):
""" Deals with errors due to missed events when we're created
inside the build script.
"""
def __init__(self):
# ignore one event, namely our own finishing
self.ignore = True
# add timing info for build start event
self.buildStarted(BuildEvent(project))
def taskFinished(self, event):
if not self.ignore:
XmlLogger.taskFinished(self, event)
self.ignore = False
listener = TardyXmlLogger()
project.addBuildListener(listener)

Ciao, Jürgen
