Hi,

I am facing problem while building servicemix from source.

I am following steps from the URL given below

http://servicemix.apache.org/building.html

Environment:

=========

Servicemix 3.2.1

Java 1.6

Steps Performed:

============

1. Downloaded the servicemix source from
http://svn.apache.org/repos/asf/servicemix/smx3/trunk/

2.      Build the code using maven tool

mvn -Dmaven.test.skip=true -Pstep1 install

mvn -Dmaven.test.skip=true -Pstep2 install

When I execute the second command I got the following exception.

Exception Raised:
