Johannes Mockenhaupt commented on TIKA-1435:
--------------------------------------------
Chris thanks.
Here's what I found out so far:
netcdf has a dependency on jdom with scope provided. Rome 1.0 has a dependency
on jdom as well and provided netcdf with jdom so far. This was probably not
intenteded and hid netcdf's dependency on jdom.
By upgrading Rome to 1.5, which in turn upgraded its jdom dependency to jdom
2.0, which changed its namespace, netcdf now fails a test because its jdom
(1.0) dependency isn't satisfied anymore.
One solution is to make the netcdf dependency explicit by adding a dependency
on jdom 1.0. This leads to both jdom 1 & 2 being on the classpath, in different
namespaces. This adds a 150k jar.
The other option is to upgrade netcdf 4.2.20 -> 4.3.22, which also uses jdom
2.0. That way, only one jdom library is needed. netcdf declares its dependency
on jdom 2.0 in that version properly (AFAIK), as it uses the default scope
rather than provided.
The later option seems good, however, the 4.2.20 version of netcdf seems to be
the last that has its dependencies released to maven.org; the later release
requires ~2 dependencies (a parent pom and udunits - see attachment), for which
a repository needs to be added. Is that an option for a project like tika?
