We are attempting to build our project using Ant so that we can
include Flex in our continuous build process. We are getting a
strange namespace error when attempting to build using the mxmlc
compiler. We created a simple HelloWorld project to verify the error
was not in our project structure. Ant fails to build the project, but
FlexBuilder has no problems. Here are the code snippets and error
message:
Error Message:
