I seems that org.elasticsearch.plugin:x-pack-core is no longer available in Elasticsearch 7. Is it still possible to implement a security extension (ie. org.elasticsearch.xpack.core.security.SecurityExtension) on Elasticsearch 7 (and what Maven dependencies should be used)? ---

I found the error. There was a problem with my Maven mirror configuration in settings.xml, so I didn't get my dependencies from Elasticsearch repository ---
