David Smiley reassigned SOLR-15017: ----------------------------------- Assignee: David Smiley > The core's lib/ folder content is not loaded in the classloader anymore when > the core's configuration does not define any <lib> element > --------------------------------------------------------------------------------------------------------------------------------------- > > Key: SOLR-15017 > URL: https://issues.apache.org/jira/browse/SOLR-15017 > Project: Solr > Issue Type: Bug > Security Level: Public(Default Security Level. Issues are Public) > Affects Versions: 8.7 > Reporter: Thomas Mortagne > Assignee: David Smiley > Priority: Blocker > Labels: regression > > I just upgraded solr-core (I'm using Solr in embedded mode) from 8.5.1 to > 8.7.0 and it seems that the lib subfolder inside a core folder is not taken > into account anymore. > Works fine when I move the lib/ folder one level up (in the Solr home folder) > but when the lib folder with the plugins is located in the core folder it > cannot find any of the classes. > I debugged it a little and I think the regression was caused by the > refactoring done in > https://github.com/apache/lucene-solr/commit/732348ec7f9c6b6f7bf9d539a40e50d16198cccc#diff-473fbcdab103c08461ad1b3c3bb1c6d56f1bcd16d6ce341d80855db2cb20a427R749 > : the handling of the lib/ core's sub folder was moved to > SolrConfig#initLibs() but unfortunately the check to make sure there is at > least one {{<lib>}} element in the configuration file was not removed which > means that if you don't have any of those then the content of the lib/ folder > is totally ignored. > That debugging was easy enough but I don't know Solr internals enough to > propose something clean to fix the issue in a pull request. > The workaround is to make sure there is at least one {{<lib/>}} element (for > example {{{{<lib dir="lib" regex=".*\.jar" />}}}}) in the core's > solrconfig.xml file. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
