Lance Norskog commented on SOLR-3760:
-------------------------------------
Here is the hard way: repack dependent jars into all contrib dist/ jars. For
example, pack everything about analysis-extras into dist/*analysis-extras*.jar.
Remove the contrib lucene libraries from the war file.
Add this to solr/contrib/analysis-extras/build.xml:
{code:xml}
<target name="addjars">
<zip destfile="../../dist/apache-solr-analysis-extras-4.0-SNAPSHOT.jar"
update="true">
<zipfileset
src="../../../lucene/build/analysis/common/lucene-analyzers-common-4.0-SNAPSHOT.jar"
excludes="META-INF/MANIFEST.MF" />
<zipfileset
src="../../../lucene/build/analysis/icu/lucene-analyzers-icu-4.0-SNAPSHOT.jar"
excludes="META-INF/MANIFEST.MF" />
<zipfileset
src="../../../lucene/build/analysis/kuromoji/lucene-analyzers-kuromoji-4.0-SNAPSHOT.jar"
excludes="META-INF/MANIFEST.MF" />
<zipfileset

<zipfileset src="lib/morfologik-fsa-1.5.3.jar"
excludes="META-INF/MANIFEST.MF" />
<zipfileset src="lib/morfologik-polish-1.5.3.jar"
excludes="META-INF/MANIFEST.MF" />
<zipfileset src="lib/morfologik-stemming-1.5.3.jar"
excludes="META-INF/MANIFEST.MF" />
</zip>
</target>

Run 'ant dist addjars'. The dist jar goes from 20k (one file) to 21M (4035
files). But, it is 21M in one deployable file. Everything is in one place! (If
the size bothers you, split the Chinese, Japanese and Polish support into
separate contribs.)
Caveats:
* This approach needs a little rearranging of the order of the build steps.
There is no place visible to the contrib build.xml where the solr/build dist
jar is finished, but not yet copied to dist/. I don't know what to do about
META-INF files in the absorbed libraries. This approach just preserves the
manifest file.
* Redundant dependencies:
** analysis-extras and extraction both use icu4j, which is a huge jar. Too bad.
** dataimporter wants all of extraction. Stick with the current arrangement.
This design is appropriate for analysis-extras, uima and opennlp. All of these
have lucene libraries and lib/ directories, and the current build arrangement
just plain does not work. It is a convenience for clustering, dataimporthandler
(-extras), extraction, langid, and velocity.
The build.xml file above needs macro-izing. As mentioned the build sequence
needs a point where the contrib build can repack the dist file inside
solr/build.

> Key: SOLR-3760
> URL: https://issues.apache.org/jira/browse/SOLR-3760
> Project: Solr
> Issue Type: Improvement
> Components: Build
> Reporter: Lance Norskog
>
> The build system packages Lucene libraries in the Solr war, but they do not
> pack libraries required by the Lucene libraries. The UIMA and analysis-extras
> contrib packages have factories for the Lucene libraries.
> The net effect is that when solrconfig.xml include <lib> directives for
> dist/xxx-contribX-xxx.jar and solr/contrib/contribX/lib, this fails because
> the lucene analyzer file inside the solr war cannot find the library files in
> solr/contrib/contribX/lib because the classloader for the war does not find
> the libraries from the <lib> directives.
> Two alternative fixes are presented below.
