[tycho-user] Unexpected NPE

[Krzysztof Daniel <kdaniel@xxxxxxxxxx>]

I'm trying to build Eclipse on arm. While running it with Tycho 0.16 I
get:

[INFO] Resolving dependencies of MavenProject:

This is weird, because other platforms (ppc, x86) work fine. Also, other
bundles, similar in shape and requirements, as
eclipse.pde.ui:org.eclipse.pde.api.tools.ee.javase16, can be built
without problems.

Do you have any clue what may be the cause of this behavior?
