Local declarations in DRL files not getting compiled

Issue

• If a data type is declared inside a DRL text, every build of the enclosing project will fail.

• Following is the sample DRL file which leads to exception in server.log

package org.kie.example;

declare Address
   number : int
   streetName : String
   city : String
end

rule "Testrule" 
    when    
    $a : Address()
then
    System.out.println("Hello World");
end

• stacttrace from server.log
