[rules-users] Not able to build documentation from version 5.0 source

[dpointzero-drools at yahoo.com.sg]

Hi,
  I am new to Drools and I am not able to build the documentation from the source code.

  The versions of the various software I am using are as follows:
- Drools: 5.0.1.26597.FINAL.
- Maven: 2.1.0
- OS: Mac OS X 10.5.7 (on an Intel-Mac)
- Java: 1.5.0_16

  The error messages I see when trying to build the documentation are as follows:

----------------------------------------------------------------------------------------------------------------

~/Developmen.../drools-5.0-src\>mvn -e -Ddocumentation clean package
+ Error stacktraces are turned on.
