Spring Content Error in Plugin
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!

Re: Spring Content Error in Plugin
Posted by "Zimmermann, Thomas" <tz...@techtarget.com>.
In case anyone else runs into this, I tracked it down. I had to force maven to explicitly include all of it’s dependent jars in the plugin jar using the assembly plugin in the pom like so:
<plugin>
<!— Includes all runtime dependencies in jar-->
<artifactId>maven-assembly-plugin</artifactId>
<version>2.5.3</version>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
Cheers!
