Adding SolrJ library to Grails 3 is causing NoClassDefFoundError error

Question

When I added SolrJ to Grails 3.2.4, And when I create the client, I get java.lang.NoClassDefFoundError: org/apache/http/impl/conn/PoolingHttpClientConnectionManager

Dependency I added: compile group: 'org.apache.solr', name: 'solr-solrj', version: '7.5.0'

Stack Trace is as follows:

Any Idea why this is happening?
