Bug#758051: libphonenumber: FTBFS: invalid build-helper-maven-plugin version

[Aaron M. Ucko]

Source: libphonenumber
Version: 6.3~svn680-2
Severity: serious
Justification: fails to build from source

Automatic builds of libphonenumber have been failing, as detailed at

https://buildd.debian.org/status/logs.php?pkg=libphonenumber&ver=6.3%7Esvn680-2

Could you please take a look?

Here are the messages that strike me as most potentially relevant:
