According to the FSF, the GPL is incompatible with the ASF License.
GPL'd code can only link against compatibly licensed code, and therefore no ASF Licensed code
can be lniked against a GPL work.

The Ant code within it requires that you include appropriate attribution and disclaimers.
The JFlex code  requires you use the GPL.

IMO, Your best bet is to get the JFlex copyright holders to waive the GPL for these purposes.
If all the copyright holders agree, then they could create an Ant task and licence it under
an appropriate license.
eg GPL with exceptions/additional clauses to allow use of the Ant code.
