[FLINK-3459] [build] Fix conflicting dependencies commons-collections
commons-beanutils and commons-beanutils-core
The Hadoop dependencies have a dependency on commons-configuration which
pulls in transitively the commons-collection, commons-beanutils and
common-beanutils-core depedencies. Commons-beanutils and commons-collection
contain classes which live in the same namespace. They are also binary
compatible but not binary identical. This is a problem for the sbt assembly
plugin which checks for binary identity. In order to solve the problem, we bump
the commons-configuration version to 1.7 so that only commons-beanutils is
pulled in. This is necessary, because the transitive promotion of dependencies
of the shade plugin only excludes the commons-beanutils dependency only from
the directly depending dependency. All parent dependencies won't have the
exclusion. This is a problem for SBT which will pull the dependency as part of
one of the parents, then. Moreover, we replace commons-beanutils by
commons-beanutils-bean-collections which contains only the non-conflicting
classes wrt commons-collections.

> Key: FLINK-3459
> URL: https://issues.apache.org/jira/browse/FLINK-3459
> Project: Flink
> Issue Type: Improvement
> Affects Versions: 1.0.0
> Reporter: Till Rohrmann
> Assignee: Till Rohrmann
> Priority: Minor
> Fix For: 1.0.0
>
>
> The current flink-shaded-hadoop2 dependency is not SBT compatible because it
> contains {{commons-collection:3.2.1}}, {{commons-beanutils:1.7}} and
> {{commons-beanutils-core:1.8}} dependencies. These dependencies contain
> overlapping classes which are binary compatible but not binary identical.
> This is a problem for the SBT assembly plugin which requires binary identity
> for merging them. Otherwise, the build is aborted. I propose to exclude the
> conflicting dependencies and use instead the
> {{commons-beanutils-bean-collection}} class which contains only then
> non-conflicting classes.
