SOLR-15178 Non-existent dependency listed in solr-core

[bszabo97]

Description

Solr-core has a dependency, org.apache.solr:server, which fails to download. For testing I created a test project here: https://github.com/bszabo97/solr_master_dep_test If I run the command gradle -q dependencies --configuration solrCore the dependency org.apache.solr:server shows up and fails, though if I run gradle -q dependencies --configuration solrCore8 it doesn't show up at all.

Solution

Adding the missing artifact.

Tests

Unit tests
