    [ https://issues.apache.org/jira/browse/TIKA-1423?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14191225#comment-14191225

Vineet Ghatge commented on TIKA-1423:

Hi [~chrismattmann] [~lewismc],

I am not sure if something changed in Maven or tika, but my tika build keeps failing with
following error 

 Failed to read artifact descriptor for edu.ucar:netcdf:jar:4.3.22: Failure to find edu.ucar:thredds-parent:pom:4.3.22
in http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will
not be reattempted until the update interval of central has elapsed or updates are forced
-> [Help 1]

The local repository - http://search.maven.org/#search%7Cga%7C1%7Cnetcdf  has 4.3.22 which
was on the system since august 2014. I have added the following tags in tika-parsers/pom.xml


Am I missing something else? Any pointer will be helpful.

> Arctic dataset contains a MIME format called GRIB -  General 
> Regularly­distributed information in Binary form http://en.wikipedia.org/wiki/GRIB .
GRIB is a well known data format which is a concise data format used in meteorology to store
historical and 
> weather data. There are 2 different types of the format ­ GRIB 0, GRIB 2.  The focus
will be on GRIB 2 which is the most prevalent. Each GRIB record intended for either transmission
or storage contains a single parameter with values located at an array of grid points, or
represented as a set of spectral coefficients, for a single level (or layer), encoded as a
continuous bit stream. Logical divisions of the record are designated as "sections", each
of which provides control information and/or data. A GRIB record consists of six sections,
two of which are optional: 
> (0) Indicator Section 
> (1) Product Definition Section (PDS) 
> (2) Grid Description Section (GDS) ­ optional 
> (3) Bit Map Section (BMS) ­ optional 
> (4) Binary Data Section (BDS) 
> (5) '7777' (ASCII Characters)
