Nick Burch commented on TIKA-1868:
----------------------------------
As explained by several people on the mailing list, you shouldn't be depending
on the Tika Server jar! It's intended as a standalone runnable server.
To include Tika in your own project, you should depend on {{tika-parsers}} if
you want everything, or {{tika-core}} if you don't want any parsers or
detectors (just core + mime), or the OSGi bundle if you're in an OSGi
environment. You are welcome to depend on {{tika-parsers}} and exclude a few
dependencies, if you don't want those specific parsers. Alternately, the Tika
2.x branch has the parsers split out into groupings, so you could have all
parsers, or just a few.
> create clean tika-server jar and shaded classifier jar

> Key: TIKA-1868
> URL: https://issues.apache.org/jira/browse/TIKA-1868
> Project: Tika
> Issue Type: Bug
> Components: server
> Affects Versions: 1.11, 1.12
> Environment: n/a
> Reporter: John Patrick
> Labels: github-import, maven, newbie, patch
> Fix For: 1.13
>
>
> If using tika-server-VERSION.jar as a standalone component it works. But if
> you use it as a dependency so is included with other jars then it causes
> classpath issues specifically around jackson.
> The project I'm working on is using Jackson 2.6.1, we have just added tika
> but when adding tika-server-VERSION.jar we have discovered it contains
> Jackson 2.4.0 classes.
> I've update the maven build so two jar's are now created.
> 1) tika-server-VERSION.jar correct clean jar
> 2) tika-server-VERSION-standalone.jar what was previously created
> This in my view is more inline with how maven should be being used to create
> jars as the previous way restricted the consumers ability to override maven
> dependencies.
> I've also updated the documentation in source control that refs to
> tika-server to include the new tika-server standalone jar. I realize other
> documentation might also need to change.
