Tim Allison commented on TIKA-4945:
-----------------------------------
Thank you for opening this. We have no active contributors with much osgi
experience and two open PRs on osgi specifically. Would you be willing to help
us with or reviews and testing with SNAPSHOT versions?
Thank you, again!
> Problematic OSGi metadata in MANIFEST.MF of 4.1.0

> Key: TIKA-4945

> Project: Tika
> Issue Type: Bug
> Components: core
> Affects Versions: 4.1.0
> Environment: OSGi/Equinox
> Reporter: Ed Merks
> Priority: Major
>
> When trying to install the following version in an OSGi (Equinox) environment:
> [https://repo.maven.apache.org/maven2/org/apache/tika/tika-core/4.1.0/]
> It fails like this:
> {color:#ff0000} ERROR: org.eclipse.equinox.p2.director code=0 Missing
> requirement for filter properties ~= $0: Apache Tika core 4.1.0
> (org.apache.tika.core 4.1.0) requires 'osgi.serviceloader;
> (osgi.serviceloader=org.apache.tika.detect.Detector),
> filter=(!(org.eclipse.equinox.p2.disable.require.capability.osgi.serviceloader=true))'
> but it could not be found{color}
>
> I believe the OSGi metadata is ill-defined. In particular the following
> aspect. There are Require-Capability declaration for which there do not
> appear to be matching ProvideCapability declarations:
