    [SPARK-12712] Fix failure in ./dev/test-dependencies when run against empty 
.m2 cache

    This patch fixes a bug in `./dev/test-dependencies.sh` which caused 
spurious failures when the script was run on a machine with an empty `.m2` 
cache. The problem was that extra log output from the dependency download was 
conflicting with the grep / regex used to identify the classpath in the Maven 
output. This patch fixes this issue by adjusting the regex pattern.
    
    Tested manually with the following reproduction of the bug:
    
    ```
    rm -rf ~/.m2/repository/org/apache/commons/
    ./dev/test-dependencies.sh
    ```
