TIKA-4698: Fix CompositeExternalParser failing to load in standalone OSGi
bundle (#2842)
* TIKA-4698 -- add explicit org.apache.tika.parser.external to
Import-Package
bnd only scans bytecode to auto-detect Import-Package entries.
CompositeExternalParser (in tika-core) is registered only via the
META-INF/services SPI file in tika-parsers-standard-package and is not
referenced in compiled bytecode, so its package
org.apache.tika.parser.external
was silently omitted from the generated MANIFEST.MF.
In a standalone OSGi deployment (tika-core and tika-parsers-standard-package
as separate bundles) the bundle classloader then cannot wire to the
org.apache.tika.parser.external package exported by tika-core, so the
SPI-loaded CompositeExternalParser fails to resolve.
Fix: list org.apache.tika.parser.external explicitly in Import-Package.
* TIKA-4698 -- explain why org.apache.tika.parser.external must be explicit
bnd only scans bytecode for auto-detected Import-Package entries; a wildcard
like org.apache.tika.* does not generate an import for packages referenced
only in SPI files. Without this comment a future contributor may remove the
line thinking it is redundant with the wildcard below it.
