Rupert Westenthaler created TIKA-1276:
-----------------------------------------
Summary: Missing embedded dependencies in tika-bundle
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
[103.0] osgi.wiring.package; (osgi.wiring.package=com.uwyn.jhighlight.renderer)

at java.lang.Thread.run(Thread.java:744)
{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))))
org.osgi.framework.BundleException: Unresolved constraint in bundle

{code}
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))
org.osgi.framework.BundleException: Unresolved constraint in bundle

{code}
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)

com.drew.imaging.jpeg.JpegMetadataReader.readMetadata(JpegMetadataReader.java:71)

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
