----------------------------------
Summary: Resolve package name conflicts for StandardAnalyzer to
allow Java module system support
Key: LUCENE-9317
URL: https://issues.apache.org/jira/browse/LUCENE-9317
Project: Lucene - Core
Issue Type: Improvement
Components: core/other
Affects Versions: master (9.0)
Reporter: David Ryan
To allow Lucene to be modularised there are a few preparatory tasks to be
completed prior to this being possible. The Java module system requires that
jars do not use the same package name in different jars. The lucene-core and
lucene-analyzers-common both share the package
org.apache.lucene.analysis.standard.
Possible resolutions to this issue are discussed by Uwe on the mailing list
here:

{quote}About StandardAnalyzer: Unfortunately I aggressively complained a while
back when Mike McCandless wanted to move standard analyzer out of the analysis
package into core (“for convenience”). This was a bad step, and IMHO we should
revert that or completely rename the packages and everything. The problem here
is: As the analysis services are only part of lucene-analyzers, we had to leave
the factory classes there, but move the implementation classes in core. The
package has to be the same. The only way around that is to move the analysis
factory framework also to core (I would not be against that). This would
include all factory base classes and the service loading stuff. Then we can
move standard analyzer and some of the filters/tokenizers including their
factories to core an that problem would be solved.

There are two options here, either move factory framework into core or revert
StandardAnalyzer back to lucene-analyzers. In the email, the solution lands on
reverting back as per the task list:
