Hi,
We have a custom java plugin that leverages the UpdateRequestProcessorFactory
to push data to multiple cores when a single core is written to. We are
building the plugin with maven, deploying it to /solr/lib and sourcing the jar
via a lib directive in our solr config. It currently works correctly in our
Solr 5.x cluster.
In Solr 7 when attempting to create the core, the plugin is failing with the
long stack trace later in this post, but it seems to boil down to solr not
finding a the Spring Context jar (Caused by: java.lang.ClassNotFoundException:
org.springframework.context.ConfigurableApplicationContext
The jar is imported in the file, and maven has a dependency to bring it in. The
maven build works perfectly, the dependency is built and the jar is generated.
Any ideas on a starting point for tracking this down? I’ve dug through a bunch
of stack overflow’s with the same issue but not directly tied to solr and had
no luck.
Thanks!
