+++ This bug was initially created as a clone of Bug #1247217 +++

Description of problem:

• While building a project in Business Central application, if the project contains a DRL that defines a declared type similar to the following, then the UI does not allow you to build the project.
  e.g. This is a sample rule
  ~~~
  package org.test.declare;

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

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

While building a project which contains a DRL similar to above the UI complains that as if it could not find a class with the type "org.test.declare.Address" inside the project classpath. It is a valid use case as per the documentation and looks to be a serious issue blocking this kind of use case from being used by users.
