Nick Burch commented on TIKA-1276:
----------------------------------
The control over what goes into the bundle is in the pom file - any chance you
could work up a patch to the tika-bundle pom which includes these missing jars?
In terms of testing, I wonder if it would be worth writing a unit test that
asks the Tika Core service loader for a list of all the parser classes defined,
then checks each one in turn to ensure it was correctly loaded and registered,
and getSupportedTypes can be called. That wouldn't ensure that the parsers
worked (that would need test files), but at least it would cover the case where
parsers don't get loaded as they have unsatisfied dependencies

> Key: TIKA-1276
> URL: https://issues.apache.org/jira/browse/TIKA-1276
> Project: Tika
> Issue Type: Bug
> Components: packaging
> Affects Versions: 1.5
> Environment: OSGI, Apache Felix via Apache Sling Launcher
> Reporter: Rupert Westenthaler
>
> While updating from tika 1.2 to 1.5 I that the
> `org.apache.tika:tika-bundle:1.5` module has some missing dependences.
> 1. `com.uwyn:jhighlight:1.0` is not embedded
> Because of that installing the bundle results in the following exception
> {code}
> org.osgi.framework.BundleException: Unresolved constraint in bundle
> org.apache.tika.bundle [103]: Unable to resolve 103.0: missing requirement
> [103.0] osgi.wiring.package;
> (osgi.wiring.package=com.uwyn.jhighlight.renderer))
> org.osgi.framework.BundleException: Unresolved constraint in bundle
> org.apache.tika.bundle [103]: Unable to resolve 103.0: missing requirement

> {code}
> 2. `org.ow2.asm:asm:4.1` is not embedded because
> `org.apache.tika:tika-core:1.5` uses `org.ow2.asm-debug-all:asm:4.1` and
> therefore the `Embed-Dependency` directive `asm` does not match any
> dependency.
> Because of that one do get the following exception (after fixing (1))
> {code}
> org.osgi.framework.BundleException: Unresolved constraint in bundle
> org.apache.tika.bundle [96]: Unable to resolve 96.0: missing requirement
> [96.0] osgi.wiring.package;
> (&(osgi.wiring.package=org.objectweb.asm)(version>=4.1.0)(!(version>=5.0.0))))

> There are two possibilities to fix this (a) change the `Embed-Dependency` to
> `asm-debug-all` or adding a dependency to `org.ow2.asm:asm:4.1` to the
> tika-bundle pom file.
> 3. `edu.ucar:netcdf:4.2-min` is not embedded
> Because of that one does get the following exception (after fixing (1) and
> (2))
> {code}
> org.osgi.framework.BundleException: Unresolved constraint in bundle
> org.apache.tika.bundle [96]: Unable to resolve 96.0: missing requirement
> [96.0] osgi.wiring.package; (osgi.wiring.package=ucar.ma2))

> 4. The `com.adobe.xmp:xmpcore:5.1.2` dependency is required at runtime
> After fixing the above issues the tika-bundle was started successfully.
> However when extracting EXIG metadata from a jpeg image I got the following
> exception.
> {code}
> java.lang.NoClassDefFoundError: com/adobe/xmp/XMPException
> at
> com.drew.imaging.jpeg.JpegMetadataReader.extractMetadataFromJpegSegmentReader(JpegMetadataReader.java:112)
> at

> at org.apache.tika.parser.jpeg.JpegParser.parse(JpegParser.java:56)
> [..]
> {code}
> Embedding xmpcore in the tika-bundle solved this issue.
> NOTES:
> * The Apache Stanbol integration tests only covers PDF, JPEG, DOCX. So there
> might be additional issues with other not tested parsers.
> * I was updating Tika from version 1.2 to 1.5. This means that all versions >
> 1.2 might also be affected by this.
> * The following dependencies embedded by the tika-bundle are in fact OSGI
> bundles and would not be needed to be embedded: commons-compress, xz,
> commons-codec, commons-io
