Hi,
I have very very simple task - we need to protect access to Solr if request
doesn't have specific header. Solr 7.3 is running in cloud mode. Was
implemented custom auth plugin:
package com.custom.solr.core;
import org.apache.solr.security.AuthenticationPlugin;
public class RestrictDirectAccessPlugin extends AuthenticationPlugin {
private static final Logger LOGGER =
LoggerFactory.getLogger(MethodHandles.lookup().lookupClass());
private static final String X_HEADER = "X-HEADER";
@Override
public void init(Map<String, Object> pluginConfig) {
}
@Override
public boolean doAuthenticate(ServletRequest request,
ServletResponse response, FilterChain filterChain) throws Exception {
HttpServletRequest wrappedRequest = (HttpServletRequest) request;
if ("true".equalsIgnoreCase(wrappedRequest.getHeader(X_HEADER)) {
return true;
}
return false;
}
@Override
public void close() throws IOException {
}
This class is wrapped into jar. Jar added to server lib directory and
defined at solrconfig.xml:
<lib dir="/webapps/solr-plugins/" regex="custom.jar" />
But, when I am trying to start Solr, I have following error:
2019-09-19 08:51:31.667 INFO (main) [ ] o.a.s.c.CoreContainer

Why Solr doesn't see such class and how can I resolve it?
