Unable to build hadoop with --offline option

[Dmitry Sivachenko <tr...@gmail.com>]

Hello!

I am using the following procedure to build hadoop from sources:

First, run mvn -Dmaven.repo.local=/path/to/m2 to populate /path/to/m2 directory with required artifacts;

Then I always run mvn -Dmaven.repo.local=/path/to/m2 --offline so it does not download anything during the build.

It worked fine with versions 2.4.1 and 2.6.0.  But with 2.7.1 I get the following error:

<...>

Am I missing something?  What should I do in order to build hadoop-2.7.1 in offline mode?

Thanks!
