Bumps libpst version to fix TIKA-1350

[jrhe]

When parsing some emails in a PST file I get the error "Unknown message type: IPM.Note" preventing them from being parsed. This is because of an extra null byte at the end of the message class string.
This has been fixed in version 0.8.1 of java-libpst so a version bump is all that is required.

Is Java libpst 0.8.1 available in maven central? Only I'm not able to see it - http://repo1.maven.org/maven2/com/pff/java-libpst/ only shows 0.7

(We can only accept dependencies that are in Maven Central)

Why do you only accept deps that in in Maven Central? No its not. I guess I need to pester the author of libpst to publish it?

[Gagravarr]

It is ASF policy that releases that are pushed to Maven Central (which ours are) must not depend on external repos, and may only depend on other resources in Central. There's quite a few blog posts explaining the rationale for this if you google

If possible, ask the libpst author to upload to central via the sonatype oss repo - https://docs.sonatype.org/display/Repository/Sonatype+OSS+Maven+Repository+Usage+Guide . First release can be a faff, but once setup it's generally only a few mins extra work (or at least that's what I've found!). If they aren't willing/able, it's possible for someone else to push it for them, see https://docs.sonatype.org/display/Repository/Uploading+3rd-party+Artifacts+to+The+Central+Repository

Cheers for the help. The java packaging situation has changed a lot since used it!

Is there anyway I can build tika with java-libpst 0.8.1 in the meanwhile?

[Gagravarr]

I've added some stuff on the maven central requirements to the contributing page http://tika.apache.org/contribute.html

As for building Tika with libpst 0.8.1, if it's in a non-standard repo, you can always add that to your tika parsers pom, then bump the dependency and build locally. If not, you'll need to build a pom for it, install it in a repo or your local m2 repo cache, then bump the tika parsers dependency
