Issue building wso2 carbon 4.1 from source - wso2

Question

I have checked out the source using the instructions svn checkout http://svn.wso2.org/repos/wso2/carbon/kernel/branches/4.1.0 wso2carbon from here: http://docs.wso2.org/wiki/display/Carbon410/Obtaining+the+Product
I have tried running mvn install using maven 2.2.1 (rdebian-8) - the install prerequisites state that version 2.1.0 or later version of maven is ok: http://docs.wso2.org/wiki/display/Carbon410/Installation+Prerequisites
I hit the errror:
Component descriptor role: 'com.jcraft.jsch.UIKeyboardInteractive', implementation:
'org.apache.maven.wagon.providers.ssh.jsch.interactive.PrompterUIKeyboardInteractive', role hint:
'default' has a hint, but there are other implementations that don't
Searching on google, it seems this is a problem with maven 2.2.1 - http://jira.codehaus.org/browse/WAGON-393
So I tried with mvn 3.0.5 and run into the following error:
Failed tests:
test3(org.apache.axis2.jaxws.utility.ClassUtilsTests)
test4(org.apache.axis2.jaxws.utility.ClassUtilsTests)
Tests run: 457, Failures: 2, Errors: 0, Skipped: 0

EDIT: 31st May 2013
When I run mvn install -Dmaven.test.skip=true I get a little further, but run into a new error:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile (default-compile) on project axis2-transport-testkit: Compilation failure: Compilation failure:
[ERROR] /home/snowch/repos_thirdparty/carbon_kernel_4.1.0/dependencies/transports/1.1.0-wso2v8/modules/testkit/src/main/java/org/apache/axis2/transport/testkit/doclet/ResourceInfoDoclet.java:[27,22] error: package com.sun.javadoc does not exist
I'm guessing that somewhere in the source tree, someone has coded a dependency on the SUN JDK and I am running OpenJDK.
