Hi.
I'm trying why HEAD Maven is failing so badly on my machine
(Linux + JDK 1.4.1_01).
AFAICT execution of any goal that has <attainGoal> invocation
uncodintionaly fails with the following stacktrace:
[ERROR] java.lang.reflect.InvocationTargetException

Method)

Commenting out the <attainGoal> tags fixes the problem. I found the
following comment preceeding a Xerces depencency declaration in Cactus
plugin's project.xml that seems to be related to this problem:
<!-- Should not be needed but it seems there is a bug with Maven when
junit dependency is added -->
Alas, adding it to the site plugin's project.xml (where I've performed
my tests) didn't help at all. Tweaking the <classloader> property din't
help either (OK, I'dont really know if it had a chance of changing
anything...)
I was also trying to make activity plugin work. I noticed the following
problems:
1) activity plugin uses ChangeLog class that is contained in the
changelog plugin. When trying to define a jellybean
(plugins-build/activity/plugin.jelly #28) it's not able to load the
class and therefore blows up with:
ERROR] com.werken.werkz.UnattainableGoalException: Unable to obtain goal

I solved it by adding a dependency on changelog plugin and
commons-logging, which changelg itself depends on:

This got me a step further, but then again:
Warning: Caught exception attempting to use SAX to load a SAX XMLReader
Warning: Exception was: org.xml.sax.SAXException: System property
org.xml.sax.driver not specified
Warning: I will print the stack trace then carry on using the default
SAX parser
[ERROR] org.xml.sax.SAXException: System property org.xml.sax.driver not
specified
[ERROR] at
org.xml.sax.helpers.XMLReaderFactory.createXMLReader(XMLReaderFactory.java:90)
I checked $MAVEN_HOME/bin/maven script and indeed, no such property is
defined there. I also took a look at maven.bat and I spotted
org.xml.sax.driver property being set on a commented out line #59 (?!)
I added the property to bin/maven script reading:
-Dorg.xml.sax.driver=org.apache.xerces.parsers.SAXParser
But it dint't help at all: still exactly the same error message. This is
how far I got today...
Thanks everybody, and happy hacking....
