-------------------------------------

I'm going to/have fix all of those in another ticket (at least I think there's already another one for that).

>                 Key: HBASE-2982
>                 URL: https://issues.apache.org/jira/browse/HBASE-2982
>             Project: HBase
>          Issue Type: Bug
>          Components: build
>         Environment: Using eclipse maven plugin that forces usage of embedded Maven 3 for dependency resolution.
>            Reporter: James Kennedy
>   Original Estimate: 0.33h
>  Remaining Estimate: 0.33h
>
> An install of the latest maven plugin resolves dependencies with Maven 3.
> Maven 3 does not like the fact that several dependencies in the main pom.xml are duplicated.
> Below is the error message which can be fixed by removing:
> * The 2nd com.google.guava dependency from the "Test dependencies" section
> * both org.slf4j dependencies from the "Avro dependencies" section
