unable to build jira 3.0 source release

When I try the build the jira 3.0 source release I get the error which appears below.

Note: I have successfully built every source release (since 2.6.1) previously made available from atlassian.com. This has been 10 or so source releases. To build each release I have downloaded the tar.gz file to my windows xp machine (though this time I have tried both the tar.gz and the zip with the same results) and unzipped the release to a directory. I change to the jira directory and modify files as detailed below before the error output).

Then I execute the command:
maven jira:release-enterprise

Note: the same error below is returned if I only issue the command 'maven'.

Build file modifications:
goto www.atlassian.com, search for make instuctions and note them
http://www.atlassian.com/software/jira/docs/latest/building.html

unzip the file to a directory and modify the build file (jira/maven.xml) slightly
1) search for the following text: - this allows you to build the api documentation
<attainGoal name="test:mail-report"/>
and copy the following text replacing the line you searched for
<!-- <attainGoal name="test:mail-report"/> -->

2) search for the following text:
<fileset dir="${ant.location}/ant-${ant.version}"/>
and copy the following text replacing the line you searched for
<fileset dir="${ant.location}"/>

3) add the following lines to jira/build.properties
(note - I haven't figured out yet how to turn off warnings...the last two lines try to do this, but it doesn't seem to work yet):
build.compiler=jikes
ant.location=c:/apache-ant-1.6.2
build.compiler.warnings=false
nowarn=true

4) download and install apache ant to the default directory

• run the same command again with the '-e' parameter, eg maven -e jar
• search the maven-user archives for the error at
  http://nagoya.apache.org/eyebrowse/SummarizeList?listName=users@maven.apache.org
• post the output of maven -e to JIRA at
  http://jira.codehaus.org/BrowseProject.jspa?id=10030 (you must sign up first)
• run 'maven --info' and post the output as the environment to the bug above
