Java 9 issues
Hi,
I'm trying to compile my app in java 9 where i hit an issue related to
the module system of java 9. the current lucene libraries (JARs) have
the same classes in multiple JARs (considered modules in java9). the
error thrown is:
error: module ant reads package org.apache.lucene.analysis.standard
from both lucene.core and lucene.analyzers.common
error: module lucene.highlighter reads package
org.apache.lucene.search from both lucene.sandbox and lucene.core
error: module lucene.highlighter reads package
org.apache.lucene.document from both lucene.sandbox and lucene.core
error: module lucene.highlighter reads package
org.apache.lucene.analysis.standard from both lucene.core and
lucene.analyzers.common
and many more ...
the module system checks that no two named modules split a package.
the only option i have seen to solve this is to use the --patch-module
but it seems not working for me e.g.
javac --module-path lib --patch-module
lucene.core=lucene.analyzers.common -d mods/com.myApp
src/module-info.java src/com/myApp/*
any support is appreciated

So, here it is: we plan to support it. (*)
Dawid
(*) When it's stabilized and documented (it still isn't) [1]. And when
somebody has the time to do it (patches welcome, it's a major overhaul
of the build system, backward compatibility, conceptual separation of
modules, etc.).

thank you.
it will be good if Lucene team can share their plans for a full java 9
support (e.g. named modules of Lucene libraries)

Hi, small correction:

I mean "Java 9 module system". It works with Java 9!

Hallo,
as with OSGI, there is currently no support for running Lucene in Java 9. This requires a complete restructure of the Lucene/Solr package structure and that's not going to happen in the next release. You should compile and run Lucene with the standard classpath where it works without any problems! Don't put the JAR files as auto-modules on the module-path (neither at runtime nor at compile time). So stay with classpath and all should be fine.
FYI, when placed on classpath, Apache Lucene and Solr (latest 6.x) versions are compatible with the module system and its restrictions (it works with illegal-access=deny and we run our tests with it), but you cannot make modules out of the JARs.
One solutions is possible: Combine all Lucene JARs to one Uber JAR file using Maven Shade plugin and use that as a "single huge module".
