Build failing with a NPE

[galegofer]

After having the project building properly, I suddenly started having this error (no changes where made at config, I am at 0.4.1):

Sounds like #347 - please check whether the stack trace is really the same. Stock mvn would perhaps show a more meaningful exception. There is a fix in master and we should release within a couple of days.

Could you please try with 0.4.2?

Tried with 0.4.3, working. Thanks!
