Thanks Shawn,
I am now pointing solrHomeFolder to lucene-solr-master\solr\server\solr which
contains the correct solr.xml file.
Tried the following two ways to create an EmbeddedSolrServer:
1. CoreContainer corecon =
CoreContainer.createAndLoad(Paths.get(solrHomeFolder));
corecon.load();
SolrClient svr = new EmbeddedSolrServer(corecon, corename);
2. SolrClient svr = new EmbeddedSolrServer(Paths.get(solrHomeFolder),
corename);
They both throws the same exception (java.lang.NoClassDefFoundError: Could not
initialize class org.apache.solr.servlet.SolrRequestParsers).
org.apache.solr.servlet.SolrRequestParsers class is present in the
solr-core-7.0.0-SNAPSHOT.jar and this jar is present in the WEB-INF\lib folder
(in solr server) and also included as a dependency jar in the pom.xml of the
test project.
Here is the full stack trace of the exception:

I have debugged this a bit and found that this exception is thrown on the
following line in EmbeddedServer.class
_parser = new SolrRequestParsers(null);
Also, the coreContainer object has no cores at this point.
Wonder if I should update my code from master (it is now about two weeks old).
Thanks for any help.
Rohana

You said you were using EmbeddedSolrServer with 4.x, so I assumed you knew what
you were doing.
You are getting that Exception because the solr home you pointed to contains a
solr.xml file in the old solr.xml format. This format is supported by all of
4.x, but support was dropped in 5.0. The message is pretty clear -- it says
that you need to upgrade your solr.xml, and even points at some documentation.
Here's a wiki page about the old format, with a link to another page about the
new format:
http://wiki.apache.org/solr/Solr.xml%20%28supported%20through%204.x%29
Suggestion: Rather than create a File object and convert it to a Path, use NIO2
methods directly:
Paths.get("testdata/solr")
Thanks,
Shawn
