Found the missing CloudSolrClient ::Builder class in the master branch, and
the code goes a bit further now. Still Solr cloud is not starting up. It is
failing to register Solr servers with Zookeeper.
Here is the stack trace:
java.lang.IllegalStateException: Solr servers failed to register with ZK.

I looked at SolrCloudTestCase to see how MiniSolrCloudCluster should be used,
then I wrote a little program and configured ivy to pull down
solr-test-framework from 6.0.0 (getting ivy to work right was an adventure!).
Based on what I found in SolrCloudTestCase, this is the code I wrote last
evening:
public class MiniSC
{
static JettyConfig jettyConfig = null;
static MiniSolrCloudCluster msc = null;
static CloudSolrClient client = null;
public static void main(String[] args) throws Exception
{
jettyConfig = JettyConfig.builder().setContext("/solr").build();
msc = new MiniSolrCloudCluster(2, Paths.get("testcluster"),
jettyConfig);
client = msc.getSolrClient();
client.close();
msc.shutdown();
}
}
At first, I saw the same exception you got ... but after a little while I
figured out that this is because I was running the program more than once
without deleting everything in the baseDir -- so the zookeeper server was
starting with an existing database already containing the solr.xml. When
MiniSolrCloudCluster is used in Solr tests, the baseDir is newly created for
each test class, so this doesn't happen.
When I delete everything in "testcluster" and run my test code, I get the
following in my logfile:
http://apaste.info/Dkw
There are no errors, only WARN and INFO logs. At this point, I should be able
to use the client object to upload a config to zookeeper, create a collection,
and do other testing.
Thanks,
Shawn
