Issues

Failed to load class org.slf4j.impl.StaticLoggerBinder
------------------------------------------------------

::

  SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
  SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

This error is reported when the ``org.slf4j.impl.StaticLoggerBinder`` class
could not be loaded into memory.  This happens when no appropriate SLF4J
binding could be found on the class path.  Placing one (and only one) of
``slf4j-nop.jar``, ``slf4j-simple.jar``, ``slf4j-log4j12.jar``,
``slf4j-jdk14.jar`` or ``logback-classic.jar`` on the class path should solve
the problem.
