• Type: Improvement
• Status: Open
• Priority: Minor
• Resolution: Unresolved
• Ignite Flags: Docs Required, Release Notes Required

Description

Example of failure in a modular environment:
Error:java: the unnamed module reads package org.apache.ignite.internal.processors.cache.persistence.file from both ignite.core and ignite.direct.io

This type of failure is named package inference, but it is strictly prohibited http://openjdk.java.net/projects/jigsaw/spec/reqs/#non-interference

Ignite compatibility with Jigsaw is tested in a separate project. See details in
https://github.com/apache/ignite/tree/ignite-11461-java11/modules/dev-utils/ignite-modules-test#ignite-modular-environment-test-project

Following table contains currenly investigated Ignite modules if this applicability as automatic modules:

Module	Run In Modular Environment	Changeable using private API only	Notes
ignite-code
ignite-indexing	IGNITE-11464	Refacrtoing to use ignite-indexing-text may be a breaking change	Lucene artifacts exclusion is required by user manually.
ignite-compress		not releaseed	org.apache.ignite.internal.processors.compress package conflict
ignite-direct-io	blocked by indexind		org.apache.ignite.internal.processors.cache.persistence.file package conflict
ignite-spring	IGNITE-11467 blocked by indexing	org.apache.ignite.IgniteSpringBean affected
ignite-ml	blocked by indexing
ignite-log4j			But may not compile with other logging dependencies - EOL https://blogs.apache.org/logging/entry/moving_on_to_log4j_2
ignite-log4j2
ignite-slf4j
ignite-rest-http	IGNITE-11469 & Mirgate to log4j2x IGNITE-11486		Usage with slf4j may break compilation because conflict of packages
ignite-hibernate_5.3 and others	IGNITE-11485		avoid of API breaking is possibleif hibernate core classes not used by third party code
ignite-zookeeper	IGNITE-11486
ignite-spring-data_2-0	blocked by spring	org.apache.commons.logging from both commons.logging and spring.jcl conflict	https://jira.spring.io/browse/SPR-16605
ignite-ml	master 2.7
ignite-cassandra-store	IGNITE-11467 blocked by spring		Only spring needs to be fixed
