Description

Both vorbis-java-tika-0.1.jar and tika-parsers-1.1-SNAPSHOT.jar include different copies of META-INF/services/org.apache.tika.parser.Parser, which the auto-detecting parser needs to configure itself.

AFAIK, only one of these can be included in a standalone OSGi JAR, as they both have the same filename.
On my system at least, the vorbis one gets included in the JAR, and not the tika-parsers one.

This means that the Tika server is capable of auto-detecting Vorbis files, but not Microsoft Office files, which is completely broken from my POV.

Unless the (undocumented) Bnd contains some way to merge these files, I suggest either:

• excluding the one from vorbis-java-tika (easy but removes Vorbis auto-detection);
• bundling vorbis-java-tika as an embedded JAR instead of inlined (might work?);
• including a manually combined copy of both manifests in tika-server/src/main/resources (ugly, requires maintenance);
• finding or writing a maven plugin to merge these files (outside my maven-fu).

My simple workaround, which probably removes Vorbis support completely, is this patch:

tika-server/pom.xml.patch
