@vdiravka Please clarify your concern regarding logback-classic. Without
the fix, logback-classic is not on the classpath during `exec:java` maven
plugin execution. This causes the following issue:
```
[INFO] --- exec-maven-plugin:1.2.1:java (default) @ drill-common ---
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further
details.
```
