This is the known problem which has been already fixed in latest jansi.
https://github.com/fusesource/jansi/issues/165

Solution 1:
The most essential solution is to replace jansi library
(jansi-1.17.1.jar) in maven lib directory with latest jansi (v2.1.1).

Solution 2:
Replace cygwin1.dll with the latest snapshot.
https://cygwin.com/snapshots/

Solution 3:
Use workaround such as:
env TERM=cygwin mvn
