In the meanwhile I downgraded the version to 0.26.0. This is the version where update-pom goal worked.

This was done with http://git.eclipse.org/c/platform/eclipse.platform.releng.aggregator.git/commit/?id=62a27c101a261e2df0bc8af3724bc0f4fde415a4

I don't know what messed this up, but the Gerrit change ID does not exist and neither the Gerrit nor Git change was linked to this bug report. Sravan, please comment.
