static resources are not copied under m2e-webby #6

couldHoldIncluded throws a NullPointerException cause includesPatterns is null.

I just added scanner.setupMatchPatterns(); to populate It at the end of  PathCollector's constructor.

Fixed Issue under NullPointerException :
17:48:34.623 [Worker-6] DEBUG o.e.m.c.i.builder.MavenBuilderImpl -

Good Idea.

Should I create another pull request ?
