I have a simple Spring boot app and want to include Actuator health check for SOLR but seems to be giving error when running it. Anything else that needs to be added a=or configured.
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'actuatorConfiguration': Unsatisfied dependency expressed through field 'solr'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'solrClient' defined in class path resource [org/springframework/boot/autoconfigure/solr/SolrAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.solr.client.solrj.SolrClient]: Factory method 'solrClient' threw exception; nested exception is java.lang.NoClassDefFoundError: org/apache/solr/client/solrj/impl/HttpSolrClient$Builder

this.solrClient = solrClient;
}
@Override
protected void doHealthCheck(Health.Builder builder) throws Exception {
Object status = this.solrClient.ping().getResponse().get("status");
builder.up().withDetail("solrStatus", status);
// CoreAdminRequest request = new CoreAdminRequest();

// Status status = (statusCode != 0) ? Status.DOWN : Status.UP;
