Solr Core initialization failure while writing junit test cases

[Bharath Kumar <bh...@gmail.com>]

Hi All,

I am getting the below exception when trying to use EmbeddedServer for my
junit test cases. I have given the correct path to the config files. I get
the core failure even when using MiniSolrCloudCluster. The collection is
created and then deleted because core is not there. Can you please help me
on this?

Test Code:-
initCore("src/test/resources/solr/collection-name/conf/solrconfig.xml",
"src/test/resources/solr/collection-name/conf/schema.xml",
"src/test/resources/solr", "collection-name");

org.apache.solr.core.SolrCoreInitializationException: SolrCore
'collection-name' is not available due to init failure:
